SUMI-EPOXY

SUMI-EPOXY ELM is special polyfunctional epoxy resins characterized by excellent heat resistance.
They deliver high performance as matrix resins for sealing materials of electric and electronic parts,heat-resistant paints and carbon fiber composites (CFRP).

カジノ シークレット 入金 不要-434 Series

The SUMI-EPOXY ELM-434 Series comprises four-functional amine epoxy resins, namely, tetraglycidyl diaminodiphenylmethane (TGDDM) epoxy they have been successfully used for CFRPs for primary aircraft structures.resins.
They are mainly used for CFRPs, heat-resistant paints, heat-resistant adhesives. As an example,This series comes in three grades, ELM-434, ELM-434L and ELM-434VL, which have different viscosity.
