Albemarle Announces Breakthrough in Curatives Technology
Wednesday, Sep 22, 2020

Albemarle Corporation (NYSE: ALB), a leader in the development, manufacture and marketing of curative solutions, announced today it has commercialized ETHACURE® 90, a new polymer chain extender that greatly improves the processing capability of polyurea and polyurethane spray elastomer coating systems used in applications such as truck bed liners, concrete and steel coatings, potable water systems and industrial coatings. Final review by the US Environmental Protection Agency is complete and commercial sales will begin in November 2010.

ETHACURE® 90 is a unique, new aliphatic diamine chain extender for aliphatic and aromatic formulations in sprayed and hand-applied coatings.  Its low reactivity and highly compatible diamine chemistry provides formulators with improved cure-rate control in a wide range of aliphatic and aromatic systems. The new product, developed by Albemarle R&D, expands and complements Albemarle’s existing portfolio of value-adding polymer additives, such as the market-leading aromatic curatives, ETHACURE® 100, ETHACURE® 300 and ETHACURE® 420.

“Albemarle’s new ETHACURE® 90 chain extender was developed to fill a void in the market, providing an aliphatic curative with slow reactivity that provides excellent cure rate control,” said Mike Gaudet, Division Vice President of Albemarle’s Stabilizers and Curatives division. “Applicators will appreciate the way that ETHACURE® 90 extends gel time for improved processing through spray equipment.  New curatives aren’t commercialized very often and ETHACURE® 90’s slow cure time provides formulators with new formulation flexibility that they never had before.”

Key benefits of ETHACURE® 90 for formulators and applicators include:

  • Aliphatic nature provides excellent color and UV stability
  • Slow cure speed and compatibility with other amines allows for extended formulation latitude
  • Low viscosity water white liquid for easy handling
  • Not moisture or air sensitive
  • Slow gel times provide excellent processing capability through both manual and robotic plural component spray equipment without delays in through-cure
  • Produces smooth, high gloss coating finishes, avoiding the undesirable “orange peel” effect
  • Improved performance and durability in severe-service applications such as containment barriers, floors, parking garages and bridges
  • Gives coatings with improved gloss retention and good physical properties (excellent adhesion, leveling, flexibility, elongation, etc.)
