Polyvinyl butyral for coatings

Artile Topic: (PVB resin) Polyvinyl butyral for Coatings/Paints 

Polyvinyl butyral (PVB resin) is polyvinyl butyral resin. It not only has good bonding properties, but also has excellent film-forming properties and wear resistance. So iSuoChem Polyvinyl butyral is widely used in the coating industry.

Polyvinyl butyral is a solvent-based resin. It is synthesized by acetal reaction of polyvinyl alcohol (PVA) and butyraldehyde under the action of a catalyst. It is non-corrosive and has good solubility, light resistance, water resistance, heat resistance, cold resistance, oil resistance, wear resistance and corrosion resistance. This adhesive resin is non-toxic, odorless and environmentally friendly. So Polyvinyl butyral is favored by many countries that have high requirements for the environmental protection level of coatings.

Next, I will list some conventional coating application areas. At high temperatures, polyvinyl butyral can also perform well in other related coating industry applications.

1. Wood coatings: Polyvinyl butyral can be treated as surface treatment agent for plywood, hardboard, or primer for insulating materials.

2. Metal coatings: After mixing PVB with other natural resins, synthetic resins, drying oils, etc., it can improve the impact resistance, flexibility and density of thermosetting resins.

3. Concrete coating: When polyvinyl butyral solution is used as a primer, it can improve the durability of water-based paint films.

4. Waterproof coating: Polyvinyl butyral resin is used as a waterproof coating for fabrics, tents, coats, instrument bags, etc. Good results can be obtained by adding polyvinyl butyral to waterproof coatings.

5. Glossy surface protective coating: Polyvinyl butyral films show strong elongation at room temperature and can maintain this property at low temperatures, so the unique properties of polyvinyl butyral resin can be used to prepare films with excellent softness and elasticity.

6. Vacuum deposition coating: PVB solution has good adhesion to plastic surfaces, paper and metal surfaces, so it can be used as a vacuum deposition coating. For example, vacuum aluminum plating and adhesives for processed surfaces.

With the continuous development of the coating industry and the continuous improvement of environmental protection requirements, the application of polyvinyl butyral resin will be more extensive and in-depth.
