PVB Pigment Chips — High-Heat, Fast-Dispersing Colorants for PVB Formulations
Product Overview
PVB Pigment Chips use Polyvinyl Butyral as the binder, offering excellent adhesion, flexibility, and chemical resistance. They are particularly suitable for laminated and flexible coating systems.
Key Applications
- Laminated Safety Glass Coatings: Automotive safety glass, architectural laminated glass
- Plastic Coatings: Decorative plastic panels, flexible plastic films
- Flexible Industrial Finishes: Protective coatings requiring high adhesion and flexibility
Performance Summary
- Advantages: Strong adhesion, good flexibility, and high chemical resistance suitable for specialized applications like safety glass and flexible protective finishes.
- Limitations: Higher cost than NC or VC chips and moderate weather resistance.
Usage Guidelines
- 1. Reserve 10-20% solvent or water so that it can be added to adjust the viscosity after the pigment chips are dissolved;
- 2. Mix the solvent first, then add the pigment chips while stirring;
- 3. Slowly adjust the mixer to 2000rpm/min. When most of the pigment chips are dissolved, stop the machine and scrape the pigment chips attached to the barrel wall, stirring plate and bottom of the barrel into the pigment chips, then start stirring until all the pigments are dissolved. Pigment chips are completely dissolved;
- 4. After the pigment chips are completely dissolved, make up for the evaporated solvent and add the 10-20% solvent or water left before, mix evenly to make a color paste;
- 5. It is recommended to quickly pass the color paste through the sand mill to achieve better results. It can also be used directly according to the usage requirements;
- 6. You can also use pigment chips directly added to the ink formula for direct use.
The manufacturing process is basically the same as above.
Storage and use of pigment chips
The storage temperature should be 5℃-30℃, avoid high temperature and direct sunlight, and should be used within 12 months if conditions permit.
