Overview: SM - 400 genera of polyester type of dispersant, it applies to the solvent system of medium on the surface of carbon black, organic and inorganic pigment grinding dispersion, good compatibility with resin, generality, also can improve the gloss of coating, the color and brilliance.
 
Chemical composition: polymer polyester polymer
 
Physical properties:
Outside view: tan liquid
PH: 8.0 to 11.0
Amine value: 20-25 mgkoh/g
20 ℃ density: 0.87 g/cm3
Live sex: 38-41%
 
Can work, can greatly reduce the interfacial tension between the pigment and show color agent, lower the viscosity of the grinding system, and make it easier for interoperability.Especially for ordinary carbon black and organic pigment grinding dispersion, high performance/price ratio, and wide generality.Can add pigment color exhibition, especially for the poor wettability of resin, can improve the gloss.Reducing the viscosity of coating, high solid content and stability is good, the other can shorten the grinding time, improving grinding fineness.
 
Application: apply to industrial paint wood coating solvent ink
 
Recommended usage: for optimal performance, SM - 400 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: 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 190 kg/barrel.
