Hydroxyl-Modified Vinyl Chloride/Vinyl Acetate Copolymers MTA5R
New grade T-MTA5R: It is white powder、ester soluble with colorless and transparent solution, and it has excellent solvent release、film-forming、dispersibility、color contrast property and wettability.
Moreover, it has more excellent solubility、dispersibility on pigment and stronger combined strength and storage stability to thin film than TA5R grade of Nissin. It can be dissolved in various of ester and ketone solvents with moderate ethyl alcohol solvents added into the mixture solvents, which can reduce the VOC emission.
