Modified agent for Adhesive Resins

Modified agent for Adhesive Resins

Modified agent for Adhesive Resins

CARBODILITE promotes adhesion to various substrates and protects from deterioration by hydrolysis and lowering of water-absorbing property as modified agent for electronic materials such as epoxy resin.

Characteristic

  • Good adhesion promotion for metal, organic materials or inorganic materials
  • Preventing hydrolysis of ester bond and keep good adhesion
  • Lowering of water-absorbing property for epoxy resin
  • Halogen free
  • Good compatibility with various adhesives

  • V-05 has high viscosity, we recommended it warm about 158°F/70°C and use it after becoming low viscosity.
  • Don't use active hydrogen content solvent and alcohol.

Application Effects

  • Hydrolysis stabilizer for polyester resin and ester-type polyurethane resin
  • Good adhesion promotion
