VANSIL® WG Wollastonite is a high aspect ratio, long needle grade of wollastonite. It is used principally as a mineral filler and reinforcing agent to enhance mechanical strength properties in high build coatings, texture paint, and block fillers. In high film build coatings, the needle-like shape of VANSIL WG improves mud crack resistance and sag resistance, while also contributing to peak retention in texture coatings. The naturally high pH of wollastonite helps to buffer latex paints and coatings, which contributes to improved corrosion resistance and weathering. This also extends in-can stability and prolongs the lifetime of the coating. In calcium silicate board and fiber cement, VANSIL WG increases flexural and compressive strength, reduces shrinkage, and reduces cracking. It is recommended that high aspect ratio grades of VANSIL be added late in process to avoid possible damage to the needle structure from high shear mixing.

Cimbar Barimite XF is an off-white, high purity, natural barium sulfate. Barimite XF is recommended for use in coatings, indcluding automotive and industrial primes and topcoats. Additionally, Barimite XF is often used in high gloss enamels, powder coatings and semi-gloss and gloss latexes.Barimite XF can be used as a filler in polyurethane foams, plastics and plastisols, friction materials, rubbers, adhesives and acoustical compounds and other insulating materials. Barimite XF is easily dispersable and is often used to impart higher surface gloss, improved hide, improved mar resistance and impact resistance. Barimite XF also offers excellent sanding resist ance, and good scrub resistance to formulations.Barimite XF is chemically inert and is an excellent choice as a filler in corrosion resistant applications, flame retardant applications, and applications that require excellent weather resistance. Moreover, Barimite XF exhibits superior thermal stabilty up to 1580 °C. It is therefore recommended for use in heat resistant applications. Barimite XF helps increase heat distortion temperatures, and reduces compound stickiness.
