Overview: SM - 300 is polymeric dispersant, multiple anchor chain in the solvent system, PU color paste, polyester polyol (perfusion) system, the carbon black and organic pigments are exhibited excellent grinding performance, good compatibility with different resin, at the same time has a low viscosity and good liquidity, can obviously improve the toner addition amount, improve the grinding efficiency.
Chemical composition: polyurethane polymer
Physical properties:
Outside view: light yellow liquid
PH: 9.0 to 11.0
The amine value: 21-25 mgkoh/g
20 ℃ density: 1.12 g/cm3
Live sex: 100%
 
Can work:
Can significantly improve the wetting ability of toner, significantly reduce the viscosity of the grinding system, make it easier for interoperability.
Especially for grinding of high specific surface area of carbon black dispersion, have very high blackness.
Can add pigment color exhibition, especially for the poor wettability of resin, can improve the gloss.
Reducing the viscosity of coatings, improve the toner addition amount and stability is good, the other can shorten the grinding time, improving grinding fineness.
Application: apply to industrial paint wood coating polyester polyol (perfusion) system of solvent ink
Recommended usage: for optimal performance, SM - 300 should be in grinding stage before add pigment to join.
The following content based on the amount of active ingredient of pigment dispersant proportion:
Inorganic pigment: 10% according to the oil absorption
Organic pigments: 15-20% according to the BET
Carbon black: 20% according to the BET
Safety and operation: operation should strictly comply with the industrial chemical production specifications, with reference to the product's safety data sheet for more information.
Storage: should be stored in a cool, dry place, suitable for 5-25 ℃ environment.Good packaging products quality assurance period for 2 years from production date.
Packing: 25 kg/barrel 200 kg/barrel.
