Aliphatic polyurethane acrylate

B-39


Product features:

B-39 is a novel, low-viscosity, monofunctional polyurethane acrylate (PUA) that features both the rigid structure of urethane bonds and flexible carbon chains in its molecular structure. Compared to conventional monofunctional acrylate monomers, B-39 boasts outstanding characteristics such as superior flexibility, rapid curing rate, high double-bond conversion, low volatility, and minimal irritation. It can effectively enhance the wettability and leveling properties of coatings and exhibits excellent adhesion to various substrates.


Recommended use:

Suitable for applications in fields such as UV adhesives, leather, soft PVC, and metallic coil coatings; as well as systems including offset printing inks, flexographic printing inks, and screen-printing inks.

Shelf life:

Store at room temperature, sealed and protected from light. Shelf life: 6 months.

Packaging specifications:

200L packaging drum; 25L packaging drum.

Precautions:

None
