Second, overview
LD-9S is a new type of coupling agent containing alkyl sulfonyl chloride and has excellent properties.
It is widely applied with high decomposition temperature and can increase the filling of inorganic fillers to
reduce the producing cost, improve compatibility between inorganic fillers and resins, perfect the processability,
improve the productivity, enhance products’ impact strength products, tensile strength, flexibility and other
mechanical properties, especially can improve the conductivity of conductive inks.
Third, applications
Suitable for the common fillers’ filling modification in resins, also can be the thixotropy of epoxy resins and polyesters.
Appropriate for most polyemers like polyethylene, polypropylene, polystyrene, PVC, acrylic resin, hydroxyacid resin,
melamine resin, polyester, rubber.
Fit for most dry inorganic fillers like calcium carbonate, talcum powder, kaolin, wollastonite, glass fiber, silica,
titanium dioxide, especially effective for carbon black.
Can apply to high temperature resistant products for LD-9S’s decomposition temperature is up to 290℃.
Fourth, usage
General coupling agent additive amount is 0.5%-3% of the fillers and the recommended dosage is 1-1.5%. When fillers’ mesh number gets bigger the dosage of coupling agent increases accordingly,
however, the best dosage is determined by experiments.
Stir and bake the fillers in high-speed mixing machine for about 3-5 minutes( temperature is 100-110℃)，then evenly add the dispersant(usually dilute and mix the coupling agent solvent at the ratio of 1:1),
then continuously stir the mixture at high speed for 10-15 minutes, finally add other components to stir well.
Fifth, package
Package of 25、50KG plastic barrels, sealed to store indoor at normal temperature for one year.
