Abstract (en)
[origin: WO9965674A1] An edge seal comprising a concentrated topcoat with suitable additives to form a caulking compound improves the performance of appliqués. Increasingly, stringent environmental restrictions make it challenging to apply coatings (i.e., paint) by conventional processes like spray painting because of the volatile solvents and hazardous pigments. The environmental scrutiny is particularly focused upon conventional corrosion protection surface treatments, especially chromated primers and conversion coatings. We apply appliqués to provide a vapor barrier over the substrate to provide corrosion protection. We can make curved appliqués on a family of molds of different Gaussian curvature and thereby avoid making a "splash" mold of the surface of interest to create the appliqués. Using curved appliqués reduces ridges, creases, or gaps that sometimes otherwise occur with attempts to cover a surface with complex curvature with flat (planar) appliqués. Appliqués are interconnected and sealed together using a concentrated topcoat (typically a fluoroelastomer or fluoropolymer) that has volatile organic compounds stripped from it to thicken the resulting edge seal to ease its application (no drips or runs), to improve its ability to stick, and to improve its toughness and corrosion inhibiting capability. The edge seal becomes an extension of the appliqués topcoat and should possess the physical and chemical characteristics of the topcoat.
