Characteristics of Solbin

Solbin is a copolymer resin prepared from vinyl chloride, vinyl acetate, and other materials. It has the following characteristics:

1. 1. Dissolves in organic solvents such as ketone and ester.
2. 2. Forms an odorless, tasteless, and transparent film.
3. 3. Highly resistant to chemicals such as acids, alkalis, and salt water.
4. 4. Forms a coating film that is highly resistant to water.
5. 5. Coating films are fire-retardant and self-extinguishing.
6. 6. Coating films are thermoplastic and heat-sealable.
7. 7. Highly compatible with urethane and melamine resins.
8. 8. Grades with hydrophilic groups favorably disperse inorganic pigments such as magnetic powder.
9. 9. Grades with hydroxyl groups react with isocyanate to form cross-links.
