III. Product Features

Low viscosity, highly versatile

Low viscosity grade, fast dissolution rate, clear and transparent solution; Under the same solid content, the viscosity of the system is moderately increased, taking into account both construction viscosity and film-forming strength, and the formula has a high tolerance rate.

Excellent directional effect of aluminum powder and pearl powder

Efficiently guide the directional arrangement of metallic pigments, resulting in strong metallic paint flash and good dual color effect; Inhibiting floating color and flower formation, preventing aluminum powder settling, is the preferred modification additive for automotive metal base paint.

Excellent construction and drying control

Accelerate solvent evaporation, shorten surface drying time, and reduce spray dust; Improve leveling, reduce shrinkage and orange peel defects; Improve the anti adhesion and anti scratch performance of the paint film; Equipped with anti biting and anti-seepage colors to protect the bottom layer.

Weather resistant and yellowing resistant, with good hardness of the paint film

Thermoplastic cellulose ester, excellent outdoor UV stability, not prone to yellowing or powdering; The paint film has high hardness and moderate toughness. Hydroxyl group 1.5%, mainly thermoplastic, generally does not participate in crosslinking reactions, and is not recommended for use in two-component PU systems.

High solvent tolerance and wide resin compatibility

Soluble in ketone and ester solvents, capable of accommodating a large amount of hydrocarbon diluents; Excellent compatibility with thermoplastic acrylic, nitro and other resins, less prone to turbidity and precipitation, suitable for various coating and ink formulations.
