SF- 280 is suitable for solvent-based systems silicone defoamers, with a strong ability to break the bubble and foam suppression, while a high efficiency at a very low amount of added circumstances have very good results, especially in the paint and ink systems for high viscosity eliminating microbubbles, and because SF- 280 does not contain solvents, can be applied to the requirements of the system, such as solvent-free UV curing system and so on. Physicochemical parameters Ingredients: silicone mixtures containing foam breaking appearance particles: opaque viscous liquid Density: 0.94-0.99 Viscosity: 500-1200mPa active components:> 98% feature a suitable solvent-based coating systems, with excellent anti-foaming ability, quickly breaking foam; 2, especially for pigmented systems, the varnish system, you need to carefully assess their compatibility; 3, with a high defoaming efficiency, in rare cases that the added amount can exhibit an excellent effect. Applications SF- 280 is applicable to two-component epoxy systems, polyurethane systems, light-cured coatings, solvent-based or light-curable screen printing inks. At any stage of the recommended dosage generally 0.05-0.5% of the total, to join in the production, post-stirring making it possible to add the need to achieve good dispersion.
