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) Adhesives
Recommended for enhancing adhesion of epoxy, urethane, acrylic and other solventborne coatings to metal surfaces with resultant reduction in corrosion. Also enhances adhesion to many plastic surfaces. Useful in many water-borne coatings (styrenated acrylates and others) for enhanced adhesion to metal and plastic substrates. Note: Chartwell B-515.4 is recommended for acrylic latex coatings.
(2) Coatings
Recommended for dispersion of difficult to disperse pigments, i.e. phthalo blue/ green, carbon black, etc. Also for all inorganic pigments, conductive pigments and mineral fillers.
