Description

L-6212 is a specially modified grafted UV polyurethane resin. If cure L-6212 alone, its film has excellent softness and toughness It is used in coatings with high toughness requirements such as high flexibility, T-bending molding, and IMD. The cured film shrinkage of L-6212 is very small, and it has good adhesion to plastic substrates with low polarity: PET, PE, PP and metal substrates: iron, aluminum, copper, etc. it has ultra-low viscosity and strong dilubility. It can be used as a monomer to improve the flexibility and adhesion of the coating. it has good compatibility with various UV resins and can be used in various UV coatings, UV inks, UV inkjet, UV varnish, and UV roller coating.
