Summary:
SM - 128 polyurethane type of dispersant, it applies to the water system of carbon black, organic and inorganic pigment grinding scattered, obviously increase the gloss of paint, color and brilliance, also used for the preparation of general paste resin.This product does not belong to alkylphenol polyethylene ethoxy ether glycol (APEO) products.
Chemical composition: polyurethane
Physical properties:
Outside view: light yellow liquid
PH: 7.0 to 10.0
Amine value: 12 to 15
20 ℃ density: 1.01 / cm3
Live sex: 49 to 51%
 
Can work, can greatly reduce the interfacial tension of pigment, wettability, can shorten the grinding time, make it easier for interoperability.Especially for acidic surface grinding dispersion of carbon black, showing very high blackness.Can add pigment color exhibition, no resin can be used for general grinding paste.Reducing the apparent viscosity of coatings, high solid elements, how the structure of the anchor system has a good stability.
Application: apply to industrial coatings although sejiang water-based ink
Recommended usage: for optimal performance, SM - 128 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.In good packaging products quality assurance period for 18 months from date of production.
Packing: 25 kg/barrel 200 kg/barrel.
