DMPA® Dimethylolpropionic Acid GEO Specialty Chemicals, Inc., Paints & Coatings Group DMPA® Dimethylolpropionic Acid unique and versatile hindered diol molecule with both hydroxyl and carboxy functionality. DMPA is an odourless, free flowing white crystalline solid which provides superior advantages in the formulation and processing of wat...view more DMPA® Dimethylolpropionic Acid unique and versatile hindered diol molecule with both hydroxyl and carboxy functionality. DMPA is an odourless, free flowing white crystalline solid which provides superior advantages in the formulation and processing of water soluble resins. This product has a neutralization equivalent of 141.0 max., a decomposition temperature of 230°C, and a water insolubles amount of 50.0ppm max. The neopentyl structure of this trifunctional compound, having two primary hydroxyl groups and one tertiary carboxylic group, permits simplified processing by allowing the combining of all reactants in a single kettle charge. Good control of the reaction is possible due to the slower esterification rate of the tertiary carboxyl, assuring a uniform distribution of carboxyl groups along the resin backbone. The free acid group actively promotes resin water solubility or water dispersibility after neutralization with a base, easily introduces a polar group to improve coating adhesion and synthetic fiber dye receptivity, and increases the alkali solubility of deposited films. view less

It is a lower molecular weight unsaturated polycarboxylic acid polymer. This product is the solvent-free version of BYK-P 104. These additives lead to a controlled flocculation of pigments. "Bridges“ are formed between single pigment particles causing three-dimensional structures to develop. Through controlled flocculation of pigments, flooding and floating, settling, and sagging of pigments is avoided. view less
BYK®-P 104 S BYK BYK®-P 104 S is a wetting and dispersing additive for solvent-borne systems. It is a solution of a lower molecular weight unsaturated polycarboxylic acid polymer and a polysiloxane copolymer. This product can be used in the same systems as BYK-P 104. The ...view more BYK®-P 104 S is a wetting and dispersing additive for solvent-borne systems. It is a solution of a lower molecular weight unsaturated polycarboxylic acid polymer and a polysiloxane copolymer. This product 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 avoid flooding. This silicone content is additionally helpful in preventing Bénard cells and silking, and also improves surface slip, leveling and orientation of flatting agents or aluminium flakes. Therefore it is oftentimes not necessary to add a separate dosage of an otherwise needed silicone additive. view less

It is a solution of a lower molecular weight unsaturated polycarboxylic acid polymer. This product is suitable for medium to high polar systems and particularly effective in preventing flooding of titanium dioxide in combination with other color pigments. It is also used in amine-neutralized aqueous coatings; it is not compatible with mineral spirits. When used in anti-corrosion primers, in many cases the protective properties are enhanced. view less
