Model SF-1400
Description
SF-1400 is a Modified high molecular weight linear polyurethane resin is an amorphous polymer with excellent flexibility, high elongation and tensile strength. It has very high solubility stability in aromatic solvents or ketone solvents, and has good adhesion to a variety of elastic and difficult-to-adhere substrates (such as: PET, PVC, PVF, aluminum, copper, stainless steel, etc.) It can also be combined with isocyanate to make a two-component adhesive. It is mainly used to cooperate with hard resin to improve the flexibility of the adhesive and the adhesion to the substrate.
Apply
-flexible material lamination mixture.
-conductive ink and metal printing ink.
-hard resin modifier .
