YD-3361M

Epoxy Curing Agent, Pot life: 30-50 min, Viscosity (mpa·s/25℃): 150-450.

PROFILE

YD-3361M is a cycloaliphatic amine modified epoxy hardener, which is a colorless and transparent liquid. It is free of NP (nonylphenol) and exhibits excellent resistance to yellowing, making it highly suitable for use in epoxy colored sand flooring topcoats. It has good leveling properties, high gloss, and is resistant to water without whitening. Additionally, it is suitable for use in home renovation adhesive applications.

PROPERTY

  • Moderate working time
  • Excellent resistance to yellowing
  • Fast establishment of hardness in the medium to later stages.

APPLICATIONS

  • Light-colored self-leveling topcoat hardener.
  • Light-colored flat coat hardener.
  • Electronic encapsulant.
