Technical quantity
- Main components: Solution of low molecular weight unsaturated polycarboxylic acid polymer and polysiloxane copolymer
- Appearance: Yellow transparent liquid
- Active ingredient: 50% (120 ℃, 60min)
- Acid value: 110-160 mgKOH/g
Application features
- Specially suitable for medium to high polarity coating systems, used to prevent the floating color and discoloration of titanium dioxide when mixed with colored pigments.
- It can provide a desired controlled flocculation of pigments, establishing bridges between various pigment particles to form a three-dimensional network structure. The controlled flocculation of pigments effectively prevents floating, blooming, settling, and sagging.
- Enhance surface smoothness and leveling, as well as the orientation of matte and aluminum powder pigments.
