Defoaming / Levelling Agent (Rheoflow AF-8...

Description Rheoflow AF-800 is based on a silicone-free, high molecular weight acrylic surface active agent and has excellent defoaming power with good levelling properties. Especially it is superiorly effective for high viscosity paints which require a strong defoaming agent, such as mastic paints, floor coatings, film coats / gel coats and multi-component systems. Composition Specialized acrylic copolymer without silicones Properties Solid content 30.0±1.0% Viscosity(25°C) 50-200 cps Appearance Clear to light yellow liquid Density(25°C) 0.84±0.01 Solvent Mineral spirits / Toluene Advantages Excellent deaerating power during paint manufacturing and mixing process. Excellent defoaming control effect on coatings. Good flow and levelling properties. Prevent cratering, pinholes, fish eyes and another surface defects. Good film appearance and recoatable properties. Applications All solvent based coatings - Vinyls, Acrylics, Epoxies, Urethanes, Alkyds - Alkyd/Melamine, Alkyd/Urethane, Oil free alkyds etc..- Acryl/Melamine, Urethane/Melamine, Polyester/Melamine etc.. Injection molding systems -Vinyl mastic paints, Acrylic mastic paints.-Epoxy heavy duty paint and floor coatings based on Urethane or Epoxies.-Unsaturated polyester film coats and gel coats etc. -Sanding sealers, Putties and High filler loading systems etc.. Recommended Amounts and Incorporation Methods In coatings on total formulation, 0.2% ~1.0% of delivery form. Usually post-added, and dispersed uniformly. When added in pre-mix, a higher level of additive is needed than with post-addition.
