Overview: It is a polymer dispersant that stabilizes inorganic pigments and organic pigments. It has the following functions:
, improve gloss and vividness ()
, reduce floating color problems
improve Pigment tinting strength
, reduced viscosity
Compared with , it has a higher molecular weight and can more effectively prevent the flocculation of organic pigments and carbon black. Despite its higher molecular weight, it has broad compatibility with a variety of resins. The viscosity of ground color paste will be lower than that of other polymer dispersants, and it can also be used in pure white paint.
Chemical composition: Polyurethane
Physical properties: Active component:
Solvent: Butyl acetate/methoxypropyl acetate/isobutanol
Amine value: -
Color: Highest
Application: Used in high-quality industrial coatings such as automotive topcoats (original and refinished), coil coatings and two-component polyurethane coating systems, and can also be used in grinding pastes ( See the introduction of micro-resin colorants for polymer dispersants).
Recommended dosage: Add before adding pigment during the grinding stage. Calculated according to the amount of pigment based on the active component of the dispersant:
Inorganic pigments: according to oil absorption
Organic pigments: - according to B value
Carbon black: according to B value
Storage: should Store in a cool and dry place. For products that are well packaged, the warranty period is one year from the date of production, and the expiry date is marked on the packaging barrel.
