With the Acquisition of Witton Silylated Polyurethane Resins, GE Now Offers a Broad Portfolio of SPUR+* Prepolymers for Formulating Sealants/Adhesives


WILTON, CONN. - Oct. 24, 2005 - GE - Advanced Materials, Silicones today announced the acquisition of a group of high-quality silylated polyurethane resins from Witton Chemicals Ltd., a U.K.-based company, to complement the launch of GE's third generation of SPUR+* prepolymers into the coatings, adhesives, and sealants industries. With the acquisition of Witton's silylated polyurethane resins, formulators can now benefit from one-stop shopping provided by GE's multi-product portfolio of prepolymers. All GE's silylated polyurethanes - including the complementary Witton products that will be offered under GE's SPUR+ trademark - have proven compatibility. The SPUR+ prepolymers are free of isocyanates and plasticizers, and offer an array of superior properties such as ease of use, low viscosity, paintability, longer shelf life, and improved chemical resistance and mechanical performance.

Witton, which has built a reputation in Europe for high-quality products for the adhesives and sealants industry, has worked closely with both GE and GE's previously acquired OSi Specialties business since 1996. Two Witton products - WSP 725 and WSP 627 - will become SPUR+ 1010 LM prepolymer (low modulus) and SPUR+ 1050 MM prepolymer (medium modulus), respectively.

"GE acquired industry-proven materials from an industry leader to create this multi-product offering," said Ian R. Moore, general manager of GE's Silanes, Resins & Specialties. "This approach will benefit formulators by taking the guesswork out of prepolymer interactions, simplifying ordering, and supporting growth into new industries interested in lowering environmental impact of isocyanates. And GE plans to develop new additives that will further enhance the performance of SPUR+ resins and improve adhesive/sealant technology in many applications."

SPUR+ prepolymer technology, combined with new Silquest* silane adhesion promoters, offers high-performance properties and easy formulation. Professional contractors appreciate the excellent application characteristics of SPUR+-based sealants, and the subsequent good adhesion to a host of difficult materials, including primerless wet and dry concrete, glass, metals, and plastics. SPUR+ prepolymer-based sealants offer excellent resistance to water and chemicals. And because these polyurethanes are free of isocyanates, they help minimize impact on the environment.

The new line of SPUR+ prepolymers was launched on Oct. 10, 2005 at the Adhesives & Sealants Council Fall seminar in Louisville, Kentucky.
