Dynasylan 4144 Polyethyleneglycol-functional alkoxysilane Degussa-Silanes Adhesion promoter / Bonding agent >> Organofunctional silane Polyester >> Unsaturated Coatings Pigment concentrates As a supplier of innovative silane solutions, Degussa has developed a non-ionic silane which imparts outstanding wetting and dispersibility to fillers and pigments in a great variety of resins and solvents. Dynasylan® 4144 helps to control rheological properties and to reduce viscosity in highly-filled polymer systems, like aluminum trihydroxide-filled polyesters or SMCpastes. Contrary to most other organofunctional silanes, Dynasylan 4144 features chemical polarity yet remaining chemically not reactive. A of such the product is used as a hydrophilic compatibilizer rather than a covalent adhesion promoter. Dynasylan® 4144 permits workable viscosities at well over 250 phr aluminum trihydroxide loading in unsaturated polyester resins. Further more, Dynasylan® 4144 can be used as anti-settling agent for corrosion inhibitors in glycol based cooling agents. As a non-coupling silane Dynasylan® 4144 can also be used as a slipping agent to simply modify a surface. Dynasylan® 4144 is a ready-for-use silane and is soluble in water and most organic solvents. It can be added neatly to a blend of filler or pigment and resin, or it can be used for the pretreatment of the filler or pigment. Dynasylan® 4144 helps to increase pigment dispersion predominantly in aqueous media, thus leading to an enhanced gloss of a typical coating. Polyethyleneglycol-functional alkoxysilane. Used for enhanced gloss of a typical coating. Possesses increased pigment dispersion.
