Advances in silicone technology enable today's exterior paints and coatings to last longer and stand up to sun, salt, pollution and age better than ever. Paints made with silicones offer exceptional adhesion, pigment dispersion and chemical, weather and stain resistance. Newer silicone-enhanced paints keep the exterior coatings of houses, bridges and rail-way cars flexible so they withstand freeze and thaw cycles without cracking, chalking, peeling or blistering. Coatings on highway, oil-rig and road surfaces are less likely to corrode from oils, gasoline, salt spray and acid rain.
