Stainban™ 208 – Calcium Strontium Zinc Phosphosilicate
Stainban™ 208 is a white, non-refractive pigment especially designed to inhibit the migration of the tannin stains in coatings on a wide variety of woods. The small particle size and narrow particle distribution allows the pigment to be easily incorporated into the coating using high speed dispersion. It is compatible with a wide variety of solvent and water based resins. It is recommended for use in primers or in self-priming applications where stain inhibition is needed. Typical use levels range from 5 – 9% total formula weight.
