Specialty chemicals and curatives producer Albemarle Corp. says it has commercialized a new polymer chain extender that boosts the processing capability of polyurea and polyurethane spray elastomer coating systems.
The U.S. Environmental Protection Agency has completed its final review of the product, called ETHACURE 90, and commercial sales will begin in November, Albemarle says.
The product is an aliphatic diamine chain extender for aliphatic and aromatic formulations in sprayed and hand-applied coatings. The company says the product’s low reactivity and compatible diamine chemistry provide improved cure-rate control in a wide range of aliphatic and aromatic systems.
The curative is suitable for use in spray coatings, cast elastomers (both hot cast and cold cast), reaction injection moldings, adhesives and filament wound pipe applications, the company reports.
Albemarle's existing portfolio of polymer additives includes ETHACURE 100, ETHACURE 300 and ETHACURE 420.
"Applicators will appreciate the way that ETHACURE 90 extends gel time for improved processing through spray equipment,” says Mike Gaudet, Division Vice President of Albemarle's Stabilizers and Curatives division. “ETHACURE 90's slow cure time provides formulators with new formulation flexibility that they never had before."
The product provides excellent color and UV stability, extended formulation latitude, and easy handling to produce a smooth, high-gloss coating finish, the company says.
Slow gel times provide excellent processing capability through both manual and robotic plural-component spray equipment without delays in through-cure, according to the company. The product is suitable for severe-service applications such as containment barriers, floors, parking garages and bridges.
