NOVELTY - Environment friendly coating solution comprises 100-130 pts. wt. modified polyvinyl alcohol (PVA), 10-20 pts. wt. modified ethylene acrylic acid copolymer, 8-15 pts. wt. inorganic mineral powder, 5-10 pts. wt. decomposition inhibitor, 3-8 pts. wt. lubricant, 2-6 pts. wt. dispersant, 3-6 pts. wt. crosslinking agent, 2-5 pts. wt. heat stabilizer, 1-4 pts. wt. defoamer and 20-30 pts. wt. deionized water. USE - Environment friendly coating solution. ADVANTAGE - The PVA is modified by modified starch to improve biodegradability, can be completely degraded and slows down degradation speed by decomposition inhibitors to ensure service life and achieve environmental protection effect. The modified ethylene acrylic acid copolymer and additives ensure functional stability and has no three wastes discharge, simple process, less equipment investment, small floor area and low production cost.
