Multi-Purpose Polyurethane Waterproof Coating & Paint
Polyurethane coating applied on substrates, to form a firm, soft and seamless sealing film by chemical reaction with moisture in the air
Features
1. Pure polyurethane sealant, environment-friendly.
2. Contains no asphalt, tar or any solvents, no harm to construction personnel.
3. Free from pollution to the environment, No toxity after curing, No corrosion to base material, High solid content.
4. One component, convenient for construction, No need of mixing, surplus products should be kept in good airproof package.
5. Efficient: High strength and elasticity, resistant to acid and alkali, excellent bonding effect with concrete, tile and other substrates.
6. Cost-effectice: The coating expands a little after curing, which means it turns a little bit thicker after curing.
7. All items tested exceeds nation standard GB/T19250-2003
Usage
1. Waterproofing for basement, kitchen, bathroom, underground tunnel, deep wells structure and normal decoration.
2. Leak-proofing and penetrating-proofing of Reservoirs, water towers, swimming-pool, For Bath-pool, fountain pool, impounding reservoir, sewage cleaning pool and irrigation channel.
3. Used for preventing of leaking, corrosion and penetrating for water tanks, underground pipeline.
Bonding and moisture-proofing of various floor tiles, marble, asbestos plank and so on
Direction
The substrate should be smooth, solid, clean, dry without sharp concave and convex points, honeycomb, pocking marks, peeling, free of bulges, greasy before application. It is better coating 2 times with scraper. When the first coat isn't sticky, the second coat can be applied, the first layer is recommended being applied in thinner layer for better releasing gas generated during reaction. The second coat should be applied in different direction to the first coat. The optimal coating rate is 2.0kg/m² For thickness of 1.5mm.
Attention of operation
Wear suitable protective clothing, gloves and eye/face Protection. After contact with skin, wash immediately with plenty of water and soap. In case of accident or if you feel unwell, seek medical advice immediately

Founded in DEC. 2003, SEPUNA has been engaged in researching, manufacturing and marketing automobile sealant and adhesive for 9 years.
Since the foundation, SEPUNA Chemical has been focusing on adhesive's researching and application. Then in 2005, We acquired PUNADE technology which is from Switzerland.
Within 9 years, SEPUNA mainly develops Silicone, Polyurethane and Epoxy resin adhesives. And in the future, we will enlarge our line to Unsaturated, Natural and Acrylic Resin adhesive.
After 9 years' improvement, by the keep researching and innovation, SEPUNA is already a mature adhesive supplier with the core competitiveness.
