Germany BYK 161 dispersant

Germany BYK dispersant BYK161 product descriptions solvent-borne systems and pigment concentrates with high molecular weight wetting and dispersing chemical composition: containing high molecular weight block copolymer solution pigment affinity groups Typical Properties solvent -------- ---- propylene glycol monomethyl ether acetate / butyl acetate -------- 6/1 Typical Properties Non-volatile matter: 30% ------- Typical Properties Amine value: 11 mg KOH / g Recommended Levels% additive (as supplied) based upon inorganic pigments ---------- 10% --15% titanium dioxide ---------- 5% -6% organic pigment - -------- 30% - 90% of carbon black ------------ 70% - 140% loading and Processing Instructions For optimum performance, wetting and dispersing additives should be added to grind. Resin and solvent should be premixed and then added slowly with stirring until dissolved evenly aid. Pigments added to aid investment and then. In order to remedy the problem in the production of paints, DISPERBYK-163, DISPERBYK-164 and DISPERBYK-167 after the most appropriate use for the add was added slowly under high shear. In baking systems as improve leveling and to prevent Bénard cells should additional BYK-331. Recommended applications: industrial coatings, automotive refinish, automobile production line paint (OEM), coil coatings, apply: coatings, architectural coatings, pigment concentrates Functional Polymers amount BYK161 aid through steric stabilization of the pigment solution flocculation. They provide the same charge of different color, so the charge different pigments avoiding possible co-flocculation. Due to the small particle sizes of the deflocculated pigments, high gloss is achieved and color strength improved. In addition, increasing the transparency of transparent pigments and hiding power of opaque pigments. These products reduce viscosity, thereby improving the flow and leveling, and can increase the content of the pigment. Characteristics and advantages of the product, DISPERBYK-161 DISPERBYK-160 is easy to operate and optimize the product, its molecular weight distribution, polarity and effectiveness and DISPERBYK-160 is very similar. Storage and transport temperature is below 0 ° C, Separation or turbidity may occur, Warm to 20 ° C and mix well. Packaging: 25 kg / barrel Tel: 13501793735 Chen
