LED street light power potting silicone solid surface features

The solid surface has complexity, roughness, porosity, high energy, adsorption, and defects. The properties of any solid surface layer are quite different from those of the interior, and the difference is more pronounced after prolonged exposure. The smooth surface on the macroscopic surface is very rough on the microscopic surface, and the convex and concave are uneven, which seems to be staggered by peaks and valleys. There are many voids, capillaries, and open-celled fiber structures on the solid surface. The solid has a high surface energy and is highly adsorbable. The actual solid surface is composed of adsorbed gas, adsorbed water film, oxide, grease, dust, and the like.
