SILCOLEASE® PC-705 is a thermally curable silicone emulsion which provides an easy release surface for adhesives and other tacky materials such as pressure sensitive tapes, labels, asphalt shingle wrap, and food packaging. SILCOLEASE® PC-705 is an emulsion of a low vinyl content silicone fluid but without the methyl hydrogen siloxane crosslinker pre-added. As such, SILCOLEASE® PC-705 offers the flexibility to the formulator of being able to modify the type or the amount of crosslinker to achieve special performance characteristics. A platinum catalyst emulsion is also required. Release modifier emulsions are available which, when blended with SILCOLEASE® PC-705 in incrementally higher levels, will give correspondingly tighter release force performance. A platinum catalyst emulsion is also required.
