Gelest Introduces Functional Silane for UV Acrylated Urethane Cure Systems

Published on 2016-10-14. Author : SpecialChem

MORRISVILLE, Pa. -- Gelest, Inc. has introduced its new SIVATE™ A200 activated acrylate functional silane for use as a primer for fiber optic cladding, a coupling agent for light-cure acrylic nanocomposites, or an adhesion promoter for high-speed UV acrylated urethane cure systems.

Gelest Introduces Acrylate Functional Silane

Properties of SIVATE A200


  • It is a proprietary combination of a cyclic azasilane with an acrylate functional silane that drives a thermodynamically-favored formation of silicon-oxygen bonds that is nearly 85% complete in less than 15 seconds. 
  • The SIVATE A200 activated acrylate silane reacts with more than three times as many hydroxyl groups as conventional ethoxy silanes 
  • It has a reaction speed more than 100 times faster than conventional silanes, providing immediate adhesion. 

Benefits of SIVATE™ A200


  • Compared to conventional silanes, SIVATE A200 offers Radcure in UV, EB and Visible Light, reacts at high speed and reacts with a greater variety of substrates. 
  • It does not require moisture to initiate surface reactivity
  • It inhibits moisture-initiated crack propagation on vitreous surfaces.
  • The introduction of SIVATE™ A200 is an example of Gelest’s customer-centric research and development.
