Aliphatic polyurethane acrylate

B-450-2

Product features:

B-450-2 is a bifunctional polyurethane acrylate with a high molecular weight, containing 10% LMA monomer. It exhibits low shrinkage upon curing and excellent flexibility. It can undergo secondary thermal curing, and the cured film demonstrates outstanding tensile strength and elasticity.

Recommended use:

UV sealant, UV elastomer, 3D printing, dual-cure system.

Shelf life:

Store at room temperature, sealed and protected from light. Shelf life: 3 months.

Packaging specifications:

20L packaging drum.

Precautions:

B-450-2 will crystallize when stored at low temperatures for extended periods; heating it to 50-60℃ will cause it to become transparent.
