Aliphatic polyurethane acrylate

B-405H

Product features:

B-405H is a trifunctional, light- and moisture-curable polyurethane acrylate with excellent adhesion. It contains isocyanate groups and can cure at room temperature in shaded areas via moisture curing, or it can also be cured thermally as a two-component system.

Recommended use:

PCB conformal coating, a dual-cure system combining light and heat.

Shelf life:

In a dry, cool, and well-ventilated place. For unopened containers, the typical shelf life is 6 months from the date of manufacture.

Packaging specifications:

20L packaging drum.

Precautions:

None
