二聚体检查酸HY-004(6500-8000)

Dimer acid HY-0041.SummarizeUnder the high temperature, there will be chemical reaction on the carboxyl group, usually is react with the amines to the amide, dimer acid consist of micro monomer acid and few trimer acid, is able to dissolve in majority organic solvent, does not dissolve in the water. 2.Product classification high polymer/other high polymer. 3.Characteristic Under normal temperature, its apperence is light yellow granular substance. Avirulence, nonirritating, high viscosity and good adhesive, high flash point, high ignition point, doesn’t freeze under low temperature. It dissolves in the majority of solvents, never dissolve in the water. 4.Technical specification indicator Typeacid valuemgKOH/gsaponification valuemgKOH/gflash point°Ccolour and lustreFe-Coviscosityg/cm325°Cdimer acid Consist ofmonomer acid %dimer acid %poly acid % HY001 ≥190 ≥190260≤93000-450010-2065-7510-1 HY002 ≥190 ≥190260≤94500-65005-1070-8010-15 HY003 ≥190 ≥190260≤85500-7500≤675-85 8-17 HY004 ≥190 ≥190260≤86500-8000≤383-92 5-15 HY005≥190 ≥190260 ≤35000-7000≤ 0.598 25.Application A.Dimer acid and the amine with additive (supplementary material) participation will reactandthan produce many kinds of different molecular weights polyamide in the different amount, whichapplies massively in manufacturinggraveror flexoprinting ink. B.Dimer acid and the multi-dimensional amine reacted to produce activated amine. it’s widely applies to make the double component epoxy paint, the curing agent and the epoxy cementing material. It also can be used to make each kind of special lubricant under low temperature, the low pressure. C.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. 6. Packing: the plastic or iron drum, each content 190kg.
