Use Procedure

Generally 1.0 phr to 2.0 phr is recommended. The presence of high surface area pigment (.ie. carbon black, fine organics, fumed silica) requires the use of 1.0 - 2.0% based upon combined resin solids plus pigment weight to achieve comparable results.

COATINGS, ADHESIVES, INKS

SOLVENT BORNE PRODUCTS:Addition to the grind stage with high shear mixing is strongly recommended. WATER BORNE: Water-borne formulations will generally require 1.0-3.0 wt per cent based upon binder solids and organic pigment weight, anti-corrosive pigment weight, and carbon black. Post add or add to grind.

RUBBER COMPOUNDS and POWDER COATINGS:

It is recommended that the Chartwell product be added directly upon the silica (or other mineral), and thereafter, the mix compounded in a Banbury/ Henschel as would be conventionally done. Evaluation at 1.0, 2.0, and3.0 phr is recommended for Chartwell (liquid) products. Evaluation at 1.5 and 3.0 phr is recommended for Chartsil (solid) products. Torque and shear should be maximized.

THERMOPLASTICS, MINERAL SURFACE TREATMENT, AND OTHER APPLICATIONS:
