SilForce SL3842 is a polydimethylsiloxane addition-cure thermal solventless easy release polymer formulation that will typically be compounded as part of a multi-component system with a crosslinker and Pt catalyst.

SilForce SL3842 offers inherently excellent reactivity that allows for curing at low process temperatures with temperature sensitive filmic substrates. A low SiH:SiV ratio can also be used to minimize residual hydride interaction with the aggressive adhesive. SilForce SL3842 can also be considered for PET film along with the appropriate AnchorSil* PET anchorage additive.
