I now have a foreign customer to seek water-based OPP coating glue, requiring glue used polymer (POLYMER) is BA, not EVA or VA, what are the BA, EVA and VA, respectively, what is the difference, use them as a polymer What is the difference in glue quality? Thank you!
VA: VA, should not be a polymer, there are many abbreviations are VA, such as vinyl alcohol vinyl alcohol
EVA: ethylene - vinyl acetate copolymer. There are different grades, can be selected according to use.
BA is butyl acrylate having the formula H2C = CHCOOCH2CH2CH2CH3. Generally used as organic synthesis intermediates, adhesives, emulsifiers, coatings
