Procedure

HIGH SHEAR MIXING NECESSARY IN ALL SOLVENT-BORNE SYSTEMS

(1) Coatings/ Inks

Optimum performance is achieved when added directly to the grind stage resin and high shear mixed for 15 mins before adding other components. Must be high shear mixed with a Cowles type mixer. Milling alone is not sufficient.

(2) Adhesives

1.0-2.0 phr, post add recommended under agitation.

(3) Plastics

1.0-2.0 phf (parts per hundred filler); recommend pretreat of pigments/ fillers in a Henschel or similar mixer and subsequently compound with resin. For high surface area pigments/ fillers, i.e. fumed silica, carbon black, phthalo, and similar use 3.0-5.0 phf.

(4) Rubber

1.0-3.0 phr, add directly onto silica or other filler and compound in a Banbury mixer.

Application

(1) Pigment dispersion

Recommended for dispersion of difficult to disperse pigments, ie phthalo blue/ green, carbon black, etc. Also for all inorganic pigments, conductive pigments, and mineral fillers. Particularly useful for the dispersion of these pigments in solvent-borne coatings and polyolefins.

(2) Thermoplastics

Use of D-535.1 to treat mineral fillers, ie calcium carbonate, mica, silica, clay, etc. will result in improved physical properties of the compounded polyolefin.
