Character
Nontoxic, nonirritating, high flash point and fire point not freeze under low temperature, good viscosity and good congluti-nation. It dissolves in the majority of solvents, never dissolve in the water.
Application
Dimer acid and amine will react to produce much different molecular weight polyamide resin. Mainly used to make graver?or flexo?printing ink, epoxy paint, the curing agent and the epoxy cementing material, lubricant .Dimer acid is used to make hot melt adhesive, which is widely used to make thermoplastic product and joint of electric cable in the posts and telecommunications, the communication equipment.

The co-solvent polyamide resin mainly used in gravure printing ink, plastic surface printing inks and hot melt adhesives.The alcohol polyamide resin mainly used in flexographic printing inks, gravure printing inks.Both of them are used in over-printing varnish.
Properties: low freezing point co-soluble polyamide resin, which has well cold resisting property and indoor temperature turn frost compared with same kind of resin, which has good adhesion, excellent compatibility, good stability and high glossiness.
