On the other hand, since epoxies set slower in cold conditions, accelerators are often used when they are applied during winter months. The same accelerators can be used in warmer temperatures to speed setting for less downtime. Another working property that can use some adjustment is surface tolerance. This means that a coating is less affected by a defect of the surface or preparation. The best example is in the world of lacquers.
Contaminants present on a surface cause an effect known as fish eye.
Coronado's Smooth All added to a lacquer coating will eliminate this defect and allow the coating to flow smoothly over the surface. It works by lowering the surface tension of the coating along with special solvents to increase compatibility with contaminants. In car paints, a silicone modifier is used to eliminate fish eye. Flood's Easy Mix E-B added to a latex paint will give it some ability to penetrate into porous and chalky surfaces. This is accomplished with emulsified alkyd resins - much like Benjamin Moore's alkyd modified house paints.
