At a time when the electronic information industry is booming, water-based epoxy antistatic topcoat has become a key product to solve the problem of static electricity. ​

Environmental advantages​

Green construction: With water as the dispersion medium, there is no organic solvent volatilization during the construction process, and there is no irritating odor, which improves the air quality of closed construction environments such as electronic factories. Construction workers do not need to wear complex protective equipment, which reduces labor intensity and also reduces the cost of enterprises in occupational health protection. ​

Environmentally friendly: After the product is discarded, it will not cause pollution to soil, water sources, etc., which is in line with the concept of circular economy and sustainable development. In today's frequent replacement of electronic equipment, the use of environmentally friendly antistatic topcoat can help reduce the harm of electronic waste to the environment. ​

Core functions and performance​

High-efficiency antistatic: Through a special formula, a conductive network is constructed on the surface of the coating, which can quickly guide away the generated static electricity. The antistatic principle is to use conductive fillers (such as conductive carbon black, metal powder, etc.) to be evenly dispersed in the coating to form a continuous conductive channel to guide the static electricity to the ground. After professional testing, this topcoat can quickly reduce the static voltage on the surface of an object to between 10 to the 6th power and 10 to the 9th power Ω, meeting the strict requirements of the electronics industry for static protection. In the electronic chip production workshop, tiny static electricity may cause chip damage. The application of water-based epoxy antistatic topcoat has greatly reduced the product defect rate and ensured production efficiency. ​

Comprehensive physical properties: In addition to antistatic, it also has good wear resistance, hardness and corrosion resistance. In the data center, the heat generated by the operation of a large number of servers and the daily maintenance of equipment require the floor coating to have wear resistance and scratch resistance. This topcoat can meet this demand; in the electronic component storage warehouse, it may be exposed to some chemical cleaners. Its corrosion resistance can ensure that the coating is not corroded and maintains stable antistatic performance. At the same time, the coating has strong adhesion, is firmly bonded to substrates such as concrete and metal, and is not easy to fall off after long-term use. ​

Construction process and key points​

Base surface treatment: Strictly treat the construction base surface to ensure that it is flat, dry and clean. The concrete base surface needs to be polished and dusted to remove the surface slurry and loose particles; the metal base surface needs to be rusted and degreased. For example, in the construction of the floor of a new electronic factory, after the concrete base surface is polished, the dust needs to be thoroughly cleaned with a vacuum cleaner to ensure a good combination of the coating and the base surface. ​

Paint mixing: The paint should be mixed accurately according to the proportion, especially the amount of conductive material added must be accurate. During the mixing process, it is necessary to fully stir to make the conductive filler evenly dispersed, otherwise it will affect the antistatic performance of the coating. It is generally recommended to use mechanical stirring for no less than 10 minutes, and let it stand for 10-15 minutes after mixing to eliminate bubbles generated during the mixing process. ​

Construction and testing: Use roller coating or spraying to control the coating thickness to be uniform. The general topcoat thickness is 0.3-0.5mm. After the construction is completed, it is necessary to wait for the coating to be completely cured (usually 3-7 days, the specific time is affected by environmental factors), and then use professional antistatic testing equipment to test the surface resistance, volume resistance and other parameters of the coating to ensure that the antistatic performance meets the standard requirements. If the test does not meet the standards, the reasons must be analyzed and remedial measures must be taken in a timely manner.

In places where surface wear resistance is extremely high, water-based epoxy super wear-resistant topcoat stands out with its excellent performance. ​

Environmentally friendly characteristics

Zero pollution guarantee: using water-based formula, no harmful organic solvent emissions during production, construction and use, providing safety for the indoor environment. Use in crowded places such as school playground stands and gymnasium floors will not threaten the health of students and athletes, creating a healthy and green sports and learning environment. ​

Environmental certification blessing: obtained a number of authoritative environmental certifications at home and abroad, such as the EU SGS environmental testing certification, proving that it has reached the international leading level in environmental performance and enhanced users' trust in the product. ​

Excellent performance

Super wear-resistant performance: through special formula and advanced production process, the coating has extremely high hardness and toughness. According to laboratory tests, its wear resistance is 3-5 times that of ordinary epoxy topcoat. In places with an average daily flow of tens of thousands of people, such as shopping malls and supermarkets, the floor using water-based epoxy super wear-resistant topcoat can still maintain good appearance and performance after 3-5 years of use, greatly reducing the frequency and cost of floor renovation. ​

Excellent stain resistance and easy cleaning: The dense coating structure effectively prevents stains from penetrating. Whether it is beverages, oil stains or other stains, it can be easily wiped clean with ordinary detergents and cleaning tools. In restaurant floor coating, facing common stains such as food residues and oil stains, the stain resistance of super wear-resistant topcoat makes floor cleaning simple and quick, improving the restaurant's sanitation environment and operating efficiency. ​

Excellent comprehensive performance: In addition to wear resistance and stain resistance, it also has good corrosion resistance, weather resistance and adhesion. In outdoor parking lots, the topcoat can keep the coating from fading and cracking under long-term exposure to sunlight, rain and vehicle rolling; in industrial workshops, it can always protect the substrate from damage in the face of various chemicals and mechanical wear, and closely bond with the substrate to ensure long-term and stable protection. ​

Construction specifications and key points ​

Strict substrate treatment: The substrate is fully treated before construction to ensure that there is no oil, dust or impurities on the surface. For concrete substrates, grinding and vacuuming are required to make the surface roughness reach a certain standard to enhance the adhesion of the coating; for metal substrates, rust removal and passivation treatment are required. For example, when constructing the floor of a large logistics warehouse, after the concrete base surface is ground, it is necessary to use a professional floor vacuum cleaner to thoroughly clean the dust, and then apply the primer to further seal the base surface and improve adhesion. ​

Accurate paint mixing: Accurately mix the paint according to the proportion specified by the product, and fully mix the main agent, curing agent and diluent. Pay attention to the stirring speed and time during the mixing process to avoid excessive bubbles. Generally, low-speed stirring is adopted, and the stirring time is controlled within 8-10 minutes. The prepared paint should be used up within the prescribed use time to avoid affecting the performance of the coating. ​

Multi-layer fine construction: Generally, a multi-layer construction process is adopted, including primer, intermediate reinforcement layer and topcoat. The primer plays the role of sealing the base surface and enhancing adhesion; the intermediate reinforcement layer can be scraped with quartz sand or troweled with epoxy mortar according to actual needs to increase the thickness and wear resistance of the coating; the topcoat gives the surface the final protection and decorative effect. The thickness and uniformity of each layer should be controlled, and the drying time between layers should be strictly controlled to ensure that the coating is fully cured. Generally, the drying time of the primer is 4-6 hours, the drying time of the intermediate reinforcement layer is 12-24 hours, and the drying time of the topcoat is 24-48 hours. The specific time should be adjusted appropriately according to the ambient temperature and humidity. After the construction is completed, the coating needs to be maintained. During the maintenance period, avoid the passage of people and vehicles. The maintenance time is generally about 7 days to ensure that the coating reaches the best performance.

As a traditional floor coating, oil-based floor paint still occupies an important position in specific fields due to its unique properties. The following is an analysis of its core advantages and applicable scenarios:

1. Excellent physical properties

Due to the addition of organic curing agent, the paint film hardness of oil-based floor paint can reach a high level (such as 2H standard), and its wear resistance and compression resistance are particularly outstanding, which is suitable for heavy-duty industrial areas such as logistics warehouses, mechanical workshops, etc. Its high-gloss surface can also enhance the beauty of the floor and is suitable for commercial spaces that require visual effects.

2. Mature technology and construction experience

After years of development, the construction process of oil-based paint has been widely mastered. Experienced construction teams can complete the coating quickly and have more flexibility in handling complex base surfaces.

3. High cost-effectiveness

In terms of material cost, oil-based paint is usually lower than water-based floor paint, especially the topcoat part. For projects with limited budgets and low environmental requirements, oil-based paint is more economical.

4. Stable chemical resistance

Oil-based paint has strong tolerance to oil and chemical solvents, and is suitable for environments that are easily exposed to corrosive substances, such as auto repair shops and chemical plants.

5. Irreplaceable application scenarios

Although environmental protection policies are becoming stricter, oil-based paint is still irreplaceable in the following scenarios:

Environment with high humidity or large temperature difference: Oil-based paint has strong penetration and can adapt to some wet base surfaces.

Short-term high-frequency use requirements: such as temporary exhibition halls or rapid renovation projects, because it can be put into use after drying.
