Uses tert-Butyl acrylate is a kind of very important chemical basic raw material and intermediate, because of unique and strong active polar molecules, unsaturated double bond and carboxylic acid ester (- COOR) structure, it can be derived out many kind of the polymer formulas with the good performances, and processed in emulsion polymerization, solution polymerization and copolymerization, it can produce plastic, s crosslinking polymer such as vinyl monomer copolymerization, styrene and vinyl acetate and methyl methacrylate (mma), acrylonitrile, acrylamide, vinyl chloride, etc. Tert - Butyl acrylate carbon - carbon double bond on polymerization reaction get polymer, colorless transparent, with excellent light stability, weather resistance, water resistance, oil resistance, resistance to chemicals and good chemical properties and physical properties, strong cohesiveness, good transparency, clear film, so it is widely used in coating, synthetic fiber, synthetic rubber, plastic, leather, paper, adhesive, packaging materials, water treatment, metallurgical mining, daily chemical products, etc.
Main Uses:
Coating resin (high solid coating formula) regulator of Powder paint for thermal liquidity Automotive OEM/surface varnish, high-grade car repair paint 
Polymer paper tackifier Used as a coating material of solid drug or adhesive polymer products for hair care, such as hairspray.
