SC-907 ReactiSolve is a fast-set, reactivating pre-primer containing a series of solvents. SC-907 is a single component product. CAUTION - This material is flammable!
SC-907 ReactiSolve has been designed for use as a thin film sealer/primer. It is not intended to be applied as a coating, rather its purpose is to absorb into and completely saturate the surface of the polymer. The high rate of absorption into a substrate is due to the ultra low viscosity of the product and the high solvent content. SC-907 causes over-cured polymer membranes to become chemically active. This enhances the adhesion of subsequent coatings by creating a new temporary open-time for recoat.
Additionally SC-907 acts as a dehydrator removing moisture from the surface of the polymer. Once the excess solvents in SC-907 which cannot absorb further into the saturated surface evaporate, SC-914 Primaset should be applied as a secondary primer extending open time between the polymer surface and newly applied coatings. Reactisol is especially beneficial in the case of older, UV damaged or oxidized polymer surfaces.
