Aliphatic polyurethane acrylate

B-295A


Product features:

B-295A is a bifunctional PUA resin with a special structural design, containing 15% IBOA monomer. It features a medium-to-low molecular weight and exhibits excellent adhesion and tensile strength at break. Thanks to its unique rigid structure, this resin cures rapidly, dries well, and boasts high surface hardness. It is suitable for use in adhesives and UV-plastic coatings, allowing formulation adjustments to fine-tune hardness and flexibility while balancing resistance to boiling water, salt spray, high and low temperatures, and thermal cycling. Additionally, when incorporated into UV-plastic varnishes and vacuum-plating formulations, it enhances resistance to boiling water and to hand sweat with high pH levels.


Recommended use:

Recommended for use in adhesive systems, special screen-printing varnishes, and colored ink formulations; also suitable for applications such as plastic coating, vacuum plating, and wood flooring.

Shelf life:

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

Packaging specifications:

20L packaging drum.

Precautions:

None
