BM52

BM52, in the form of a powder, is a copolymer of methacrylates that is a kind of alcohol solubility resin and can be dissolved by ethanol and other weak solvents. It has low odor, high purity, and offers better hardness and pigment dispersion, and holds admirable adhesion on almost all nylons (PA) and metals. BM52 is widely used in coatings on special substrates, alcohol soluble inks, and eco-friendly coatings with a molecular weight of 70,000 g/mol, moisture content of equal to or less than 1.0%, and an inherent viscosity of 0.51 to 55.

BM61

BM61, in the form of a pellet, is a copolymer of methacrylates that offers performance on good durability, adhesion, low shrinkage, and good flexibility. It can be dissolved in numerous organic solvents such as chlorinated solvents, high alcohol, aromatic hydrocarbons, ketones, esters. It has good compatibility with cellulose acetate, NC, vinyl resin, and it is commonly used in UV ink formulation (OPP/BOPP film) as inert resin to reduce shrinkage and to enhance adhesion. BM61 is also broadly used in eco-friendly correction fluid, aluminum heat sealing lacquer, cardboard ink, and more. It has a molecular weight of 50,000 g/mol, moisture content of equal to or less than 0.5%, acid value of equal to or less than 6.5 mgKOH/g, and an inherent viscosity of 0.20 to 0.26.

BM61A

BM61A, in the form of a pellet, is a copolymer of methacrylates that offers performance on good durability, adhesion, low shrinkage, and good flexibility. It can be dissolved in numerous organic solvents such as chlorinated solvents, high alcohol, aromatic hydrocarbons, ketones, esters. It has good compatibility with cellulose acetate, NC, vinyl resin, plasticizer, and it is commonly used in UV ink formulation (OPP/BOPP film) as inert resin to reduce shrinkage and to enhance adhesion. BM61A is also broadly used in gravure inks, aluminum heat sealing lacquer, cardboard ink, and more. It has a molecular weight of 50,000 g/mol, moisture content of equal to or less than 0.5%, and an inherent viscosity of 0.20 to 0.26.

BM70

BM70, in the form of a pellet, is a copolymer of methyl methacrylate and methacrylic acid that is soluble in polar organic solvents such as ketones and esters and can be dissolved in esters (or ketones) for alcohol soluble inks and mixed solvent like absolute ethyl alcohol. It offers good adhesion on glass, metal, plastic, and is broadly used in glass inks, metal coatings, and more. BM70 has a molecular weight of 40,000 g/mol, moisture content of equal to or less than 1.0%, acid value of equal to or less than 70 mgKOH/g, and an inherent viscosity of 65.0 to 70.0.
