Aliphatic polyurethane acrylate

B-374


Product features:

B-374 is a trifunctional aliphatic polyurethane acrylate. Its aliphatic structure imparts excellent yellowing resistance to the resin, along with outstanding flexibility and tensile strength, and it cures rapidly. In UV-curable formulations, its hardness and flexibility can be adjusted to achieve a balanced performance in terms of resistance to boiling water, salt spray, high and low temperatures, and thermal cycling.


Recommended use:

It can be applied as a primer and topcoat for metal and vacuum-coated surfaces, UV coatings for PVC surface finishes, paper, wood products, and more. It is also suitable for use in various printing inks for cigarette and liquor packaging.

Shelf life:
