Characteristics of SOLBIN

SIOBIN is a copolymer resin prepared from vinyl chloride and vinyl acetate in addition to other element, and has the following charactersitics:

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