CHT HANSA SFA 42100 Vinyl siloxanes
Categories:	Other Engineering Material; Additive/Filler for Polymer
Material Notes:	Description: All products of the HANSA SFA 42 series are end-capped vinyl siloxanes with different molecular weights and viscosities. The reactivity of the vinyl-functional polymers can be employed in addition as well as peroxide-activated curing systems. Addition-curing chemistry based on platinum cure is the basis for formulating silicone elastomers. Our vinyl polymers can serve as basis of these formulations to achieve different levels of viscosity, hardness, and mechanical properties. Using the HANSA SFA 42 series, you can ensure that your elastomer products are highly reactive, transparent, and low in volatiles. Key Features Excellent reactivity Good stability to UV, chemicals and weathering High transparency No shrinkage during crosslinking Key Applications Intermediate for addition curing formulations Information provided by CHT Group
