Huntsman Announces New Strong-Bonding Primer System

The Woodlands, TX - Huntsman Corporation announced the availability of a new strong-bonding primer/basecoat system utilizing SUPRASEC® 9584 MDI isocyanate, for use with polyurethane, polyurea and other coatings. When mixed with castor oil, SUPRASEC 9584 is simple and easy-to-use, claims Huntsman. It will penetrate and seal the surface, leaving a smooth pinhole and bubble-free coating. Moreover, it provides adhesion to a variety of substrates and has outstanding stability at low temperatures, according to the company.

SUPRASEC 9584 can work at different volume ratios thus offering a range of stiffness and flexibility, claims Huntsman. It allows for a long work time – up to 45 minutes; a large recoat window – two to 24 hours; and curing on cold substrates, according to the company.

Huntsman claims that this new high-solids primer helps prevent topcoat leaching, bubbling and blistering. It may also be applied on damp surfaces with no bubbles or foaming, says the company. Its low viscosity makes it easy to spread or spray, and its performance can be tailored by adjusting the resin blend with amine polyols or catalysts to shorten cure time, adds Huntsman.
