Liquid urethane polymers from Bayer MaterialScience LLC improve performance of epoxy resins

Published on 2010-02-26. Author : SpecialChem

Pittsburgh -- Options for flexiblizing epoxy resins have traditionally been limited. The addition of plasticizers, for example, has generally had an adverse effect on the epoxy's mechanical properties. Now, however, there is another viable alternative: liquid urethane polymers, such as Desmocap® urethane polymer from Bayer MaterialScience LLC.

Desmocap urethane polymers can improve and/or expand the flexibility, elongation, impact resistance, tear resistance, cure rate and adhesion of epoxy resins. Epoxies incorporating urethane liquid polymers are well suited to a variety of uses, including caulks, coatings, membranes and sealants, and can also be utilized to encapsulate electrical parts.

"We've seen an increased interest in the marketplace for epoxy flexibilizers," said Jay Johnston, senior technical specialist, Bayer MaterialScience LLC. Johnston, who notes that urethane polymers can also be reacted with an amine to create a two-component polyurethane flexible sealants. "As a leader in polyurethane chemistry, Bayer MaterialScience LLC is pleased to be able to offer a solution that not only overcomes the limitations of previous technologies, but actually enhances epoxy performance."

Bayer MaterialScience LLC is one of the leading producers of polymers and high-performance plastics in North America and is part of the global Bayer MaterialScience business with nearly 15,100 employees at 30 sites around the world and 2008 sales of 9.7 billion euros. Business activities are focused on the manufacture of high-tech polymer materials and the development of innovative solutions for products used in many areas of daily life. The main segments served are the automotive, electrical and electronics, construction, medical, and sports and leisure industries.
