Recommended Levels % additive (as supplied) based upon Inorganic pigments Organic pigments Titanium dioxide BYK-P 104 BYK-P 104 S 3 - 10 10 - 20 0.5 - 2.5 BYK-P 105 2-5 5 - 10 0.5 - 1.5 The above-mentioned usage levels strongly depend on pigment particle size. Optimal levels are determined through a series of laboratory tests. Incorporation and Processing Instructions For optimum performance, these additives must be incorporated into the millbase before addition of pigments. Before processing, BYK-P 105 should be preheated until the additive has good flow properties. This facilitates more accurate dosing. Data Sheet ASW8 Issue 02/11 Applications Adhesive system Solvent-borne Solvent-free Water-reducible BYK-P 104 BYK-P 104 S BYK-P 105 recommended suitable Function These additives lead to a controlled flocculation of pigments. Bridges are formed between individual pigment particles causing three-dimensional structures to develop. The controlled flocculation of pigments prevents flooding and floating, settling, and sagging of pigments. Special Features and Benefits Especially suited for medium to high polar adhesive systems and particularly effective in preventing flooding of titanium dioxide in combination with other color pigments. It is also used in amine-neutralized aqueous systems; it has limited compatibility with mineral spirits. BYK-P 104 S BYK-P 104 S can be used in the same systems as BYK-P 104. The additive also contains a small amount of a polysiloxane copolymer to more effectively prevent flooding. This silicone content is additionally helpful in preventing Bénard cells and silking. BYK-P 105 BYK-P 105 is the solvent-free version of BYK-P 104. The additive shows a high efficiency with acrylate adhesives to prevent settling of fillers. d. su n w ay in fo . co m .cn BYK-P 104 gp Special Note There is a limited compatibility with mineral spirits and adhesives diluted with mineral spirits. Storage and Transportation BYK-P 104 BYK-P 104 S Separation or turbidity may occur during storage and transportation. Mix well before use. Warm to 30-60°C and mix well.
