D.E.R.™ 3680-X90

D.E.R™ 3680-X90 Epoxy Resin Solution is a low molecular weight epoxy resin in a xylene solution developed for use in high-solid coating formulations. When formulated with polyamine or polyamide hardeners, the binder forms an excellent base for many high-quality coatings typically used in the protection of concrete or steel.

Used in:

    • Marine and Protective Coatings
    • Civil Engineering

    Advantages:

    • Low molecular weight
    • Offers flexibility and lowers solution viscosity
