How silicone resins improve your quality and ease the applications of your paints?
Silicones consist of a backbone of altering atoms of silicon and oxygen known as a siloxane linkage (Si-O-Si)
and it is commonly used in paint and coating industries to ease the applications of paints. They are produced in a lot of forms including silicone fluids, resins, liquid rubbers and solid rubbers and used in a wide range of industries. Silicone plays various crucial roles in each industry and coating industry is one of them.They are used for base resins in the paints as a main component, silicone powders as additives and silane as pigments and fillers.
Here are the advantages of silicones in paint and coatings to improve the quality and ease the application of your paint;
1. Have better resistance to high temperatures
Silicone resins have better resistance to high temperatures than the organic resins. It improves the durability of paints and coatings and reduces the volumes of paint used over the lifetime.
2. Can aid in wetting, flow and levelling
Many things can go wrong when a coating is applied and dried and in many of these cases it is due to surface tension gradients that arise from temperature and concentration gradients; these surface tension gradients are likely to cause surface imperfections upon film drying. By lowering the overall surface tension of liquid coatings, silicone additives can aid in wetting, flow, and levelling
3. Better electrical insulation
Silicone resins are very consistent across a wide range of temperatures while organic resins decline in hot and humid conditions.
4. Flexibility
Silicone resins are easy to apply
5. Have excellent water resistance
In organic resins, absorbed water does not dissipate easily due to high hygroscopicity
6. Weatherability
Silicone resins give excellent results in resistance against UV rays.
7. Colour retention
Silicones are very useful additives to enhance the gloss and colour protection.
