GP- 673 Dimethylpolysiloxane block copolymer Genesee Polymers Flow / Levelling agent >> Silicone Lubricant >> Silicone Wetting agent/ Wet edge enhancer >> Silicone Polyurethane Coatings >> Solventborne Insoluble in water Soluble in aliphatic hydrocarbons and alcohols SILICONE POLYOL COPOLYMER GP-673 is a 100% active polypropylene oxide modified dimethylpolysiloxane block copolymer. The combination of polysiloxane and pendant polypropylene oxide segments provides excellent lubricity and low surface tension, which improves the wetting, leveling and flow of solvent-based coatings. GP-673 contains stable Si - C bonds between silicone and polyol blocks and exhibits excellent resistance to hydrolysis. Some of the special properties of GP-673 are listed below: Low Surface Tension Excellent Lubricity Non-Hydrolyzable Thermal Stability Low Toxicity GP-673 is designed to improve the quality and performance of solvent-based, baked on industrial finishes. GP-673 is also recommended for evaluation in polyurethane foam systems - as a profoamer additive. Other applications include the following: Pigment Dispersant Internal Lubricant for Plastics Thread Lubricant Wetting Agent-Solvent Systems Leveling and Flow Control Agent-Solvent Coatings Urethane Bubble Release Additive (Coatings) Antifoam-Aqueous Systems Non-hydrolyzable, active polypropylene oxide modified dimethylpolysiloxane block copolymer. Provides very good lubricity and low surface tension. Improves wetting, leveling and flow of solvent-based coatings. Offers very good resistance to hydrolysis, thermal stability and low toxicity. Can be used as a pigment dispersant, urethane bubble release additive for coatings and antifoam in aqueous systems.
