TAS-9500 Water-based epoxy thin-coat topcoat

It is composed of two-component water-based epoxy coating and water-based epoxy curing agent, filler, water-based additives, water, etc. Its seamless and smooth surface makes it very easy to clean and maintain. It has good wear resistance, corrosion resistance, impact resistance, acid, alkali, salt and other chemical substances, and is suitable for various civil and industrial floors. It is applicable to general floor coating, especially for hospitals, food factories, supermarkets, dairy factories and cosmetics factories that need to keep the floor clean and highly humid, such as underground parking lots, first floor floors, and occasions that require low odor.

Construction reference
Surface treatment

● For all new and old concrete floors, the concrete strength must reach C25 or above. The surface stains, loose soil, moisture, loose old paint film and other attachments must be completely removed until the solid concrete is exposed. For concrete contaminated by chemicals or other substances, they should be removed until the solid concrete is exposed. Make the surface clean, dry and flat.

● Old floors with paint
Completely grind away loose or incompatible old coatings to expose the concrete surface. Clean, dry and intact compatible coatings do not need to be removed.

● Oily floors
Oil stains will seriously affect the adhesion of floor coatings to the base surface. Oily floors must be completely cleaned and polished.

● New concrete floors
Make sure the floor has exceeded the maintenance period and the moisture content of the floor is less than 6%. It is critical to use mobile sandblasting tools and grinding equipment to treat the concrete surface to achieve the correct surface roughness.

Paint mixing method
After fully stirring component A, pour component B into component A according to the specified ratio, then stir evenly with a special stirrer, and dilute with water to the construction viscosity. This product should be prepared as needed, and should be used up within the use period to avoid waste of gel.
Construction conditions
Painting environment temperature range: 5~35℃. The base surface temperature is at least 3℃ higher than the air dew point temperature.
Painting environment humidity range: Relative humidity is less than 80%.
Ventilation conditions: Air circulation must be maintained during construction to facilitate the evaporation of water. Compulsory measures must be taken in poorly ventilated environments. This is an important guarantee for the success of construction, otherwise the coating will have whitening, poor adhesion, low hardness and other drawbacks.
Special precautions: Construction is not allowed when the temperature is below 15℃. Topcoat and varnish cannot be applied when the relative humidity exceeds 85%. Primer and topcoat must be used up within the specified time when it rains or when the weather is prone to moisture. After exceeding the use time, the viscosity cannot be diluted with water and reused. Otherwise, various paint diseases such as color difference, inconsistent gloss, and reduced hardness are prone to occur. When applying topcoat, there must be no visible water on the roller or brush. Too much water added to the topcoat will cause the performance of the paint film to deteriorate, such as decreased hardness, gloss, and uneven color. The roller should be cleaned with clean water again after every two hours of construction to prevent the roller from falling off. The topcoat takes a long time to level (i.e., it leveled slowly). If the surface is uneven, there is no need to roll back and forth many times. When scraping sand or putty, add sand or powder directly after the two components are fully mixed. Do not add water, otherwise it will affect the strength of the paint film. Each of the above-mentioned processes cannot be applied too thickly at one time, otherwise it will affect the curing effect, such as slow drying, reduced gloss, and reduced paint film strength. It is just for the convenience of construction, so under the conditions of meeting the construction, the less water is added, the better the curing effect. In each of the above-mentioned processes, temporary water addition must be added after components A and B are fully mixed. In principle, the less water added, the better the performance of the paint film, such as strength.

Safety measures

Product safety and health data are available upon request. The following measures should be ensured during any paint application:

● Avoid contact with skin and eyes.

● If paint comes into contact with skin, wash with warm water and/or an appropriate detergent. If paint comes into contact with eyes, rinse with plenty of water and seek medical attention immediately.

● Ensure good ventilation.

● Paint contains flammable substances. Please keep away from sparks and prohibit smoking in the vicinity.

● Comply with all health and safety regulations on site.
