Additive effect pigments and Performance Overview Introduction

The amount of additive is generally between 0.1 to 2.0%, by adding the pigment used to improve various properties of the pigment, such as to adjust the viscosity, anti-settling crust, accelerate the drying, anti-dehydration, defoaming defoaming improve thixotropy, Anti blurs, eliminating caking, antibacterial and antifungal, improved flow and leveling, adjusting gloss, improved stability, improved brush, improve hiding power and so on.
Thixotropy; thixotropic coating with agitation and the next still carried in gel - liquid - gel nature of the process. Coating at rest is usually solid or gel form, but becomes agitated good mobility of the material, this situation does not drip through the coating to the show. Gelatinous coating formed on the brush, the brush will not flow or drip down, brushing becomes liquid when can a good flat brush, brush formed on the surface after construction gel, to prevent sagging or falling blocks.PVC plasticizer
Increased sediment and expansive agent material, you can change the pigment in the binder dissolution characteristics, giving the viscous flow properties, such as bentonite, specialty of Que-like compounds, amines soap.
Of the gel and into the liver; for said coating, painting or enamel solids formed after aging capacity, in fact, is the dispersion of solids in a liquid case, although the nature of a solid, but still maintain a substantial amount of liquid. The reason why the phenomenon of gel or liver, and the base material because the reaction of the pigment, such as basic pigments (zinc oxide, white lead and red lead) in an acidic binder grinding. Oxidized rubber paint cans hidden in the formation of colloidal sometimes, you can add a small amount of chlorine propylene oxide additives to prevent this situation from occurring.PVC impact modifier
