Vinyl chloride/vinyl acetate modified resin Solbin

Solbin is a modified resin that combines the toughness and chemical resistance of vinyl chloride, the strong adhesiveness and plasticity of vinyl acetate, and other polar groups that enhance adhesive properties and solubility. Due to its many outstanding characteristics, including its lack of odor or taste and high resistance to water absorption, Solbin is used as a binder for magnetic cards and tapes, as a coating agent for beverage cans and moisture-proof cellophanes, and also as part of various paints, inks, and adhesives.

Characteristics of Solbin

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

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