Hexane, 1,6-diisocyanato-, homopolymer, 2-hydroxyethyl acrylate-blocked

Hexane, 1,6-diisocyanato-, homopolymer, 2-hydroxyethyl acrylate-blocked, identified by CAS 264888-31-5, is a multifunctional urethane acrylate oligomer. It is used as a reactive building block in UV/EB-curable systems.

This chemical delivers high crosslinking density, surface hardness, and scratch resistance in radiation-cured formulations. In UV-curable coatings for wood, plastic, and metal substrates, it contributes to high-gloss, abrasion-resistant topcoats.

Cure speed and film integrity are critical performance factors for this material. Printing and packaging applications rely on it for radiation-curable inks and overprint varnishes that require flexibility alongside surface durability.

In adhesive and sealant formulations, the aliphatic HDI backbone provides excellent weathering and yellowing resistance. This makes it highly suitable for outdoor applications and specialized optical bonding requirements.

Plastics processors use it in UV-curable hardcoats for polycarbonate and other transparent substrates. It is particularly effective where optical clarity must be maintained over the lifespan of the finished product.

The product is supplied as a viscous liquid, typically requiring moderate warming for handling and blending. It is available in a quality consistent with industrial radiation-cure raw material specifications.

Standard supply is provided in technical grade to meet the rigorous demands of coatings and ink formulators. Packaging options typically range from small drums to IBC quantities depending on specific volume requirements.
