Outline

Polyester urethane type adhesives and coating agents using the copolyester VYLON® as their basis.

Among modified copolyester resins of Toyobo, urethane modified copolyester resin is the Vylon® UR series.
Vylon® UR series is the polyester urethane designed based on the copolyester technology accumulated in Toyobo for many years.
Utilizing its excellent properties, it is used in binders for magnetic tapes, adhesives, paints, coating agents, and blending agents for modification.

Feature

  • 1. Excellent adhesive property and adhesion
  • 2. Forms tough coated film
  • 3. Provides the resins with variety of modulus
  • 4. Excellent hydrolysis resistance
  • 5. Heat resistance is improved by using crosslinking agent
  • ● VYLON® UR series is urethane modified co-polyester resin which is based upon the aromatic polymer technology.
  • ● Excellent adhesion property to PET, PVC films or metals.
  • ● Excellent pigment (iron oxide, titanium dioxide, etc.) compatibility and disperse ability.
  • ● Excellent hydrolysis resistance and high modulus obtained by aromatic polymer chain technology.
