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

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.
