The SYH Surface Sealant is a silicon-free fluoro-polymer resin providing protection for painted and GRP surfaces from common causes of degradation – ultra violet light, atmospheric pollution, acid rain and bird lime.

SYH Surface Sealant is fast, easy and fool proof to use and is water cured. It bonds to the paint surface creating a protective-coating. (Flexible enough to withstand 9” in flight expansion and contraction of Concorde).
