Vinyl Ester FRP Heavy Anticorrosive Coating

Vinyl Ester FRP Heavy Anticorrosive Coating

Product Overview Product characteristics
With strong perneability, acid resistance, salt tolerance and various orgainc solvent resistances, it is featured by high surface hardness and good compactness; mechanical properties are excellent, heat resistance, low tensile strength viscosity, easy construction and can solidify under low temperature.
System characteristics
Floor of chemical corrosive area for anti-corrosion tank and heavy machinery surface treatment as well as anti-corrosion engineering, sewage basin and chemical pool of petroleum industry, etc.
Construction Process ◇ Base layer treatment: Scrap and paint epoxy osmotic primer: 1.Use vinyl resin primer: mix vinyl resin and hardener by proportion and stir them evenly; 2.Scrape fundation ground roundly for one time to strengthen surface adhesion; 3.The first floor base layer shall be made waterproof layer well;
◇ Spread and stick glass fabric; pour mixed vinyl ester resin and hardener on glass fabric and strike off;
◇ Intermediate concrete screed; use floating of vinyl resin: Add quartz of 40-100 meshes to stir evenly after mixing main paint and hardener by proportion, and use scraper to scrape roundly, after cure, grind tool mark defects and clean them up;
◇ Putty layer: Use floating coating of vinyl resin: Add appropriate filler to stir evenly after mixing main paint and hardener by proportion, use scraper to scrape the whole to fouces on repairing and filling the freeze-proof defects, after cure, grind tool mark defects and clean them up with cleaner and wrong wet towel;
◇ Surface layer trowel scraping self-leveling topcoat requires uniform layer without holidays, after construction, the integral shall be bright and clean with unifrom colors but no hollowing.
