Serdas GBR Surface active agents silicon free Condea Servo Defoamer / Antifoaming agent >> Silicone-free >> Surfactant & Fatty acid Coatings >> Waterborne SERDAS Anti-foaming agents SERDAS GBR Anti-foaming Agent GENERAL INFORMATION SERDAS GBR is an economical liquid defoamer with an excellent stability, recommended for water-based systems, such as emulsions, emulsion paints and water dilutable resin systems APPLICATION AND PROPERTIES PROPERTIES SERDAS GBR is specially recommended for systems with good emulsifying properties, such as surfactant stabilised emulsions and emulsion paints. SERDAS GBR coalesces minute air bubbles in the water phase, allowing them to rise and suppress foaming during the manufacture, the let-down-process, the canistering as well as during the application of the paint. SERDAS GBR has excellent stability properties and can be stored for many months without the risk of separation of sedimentation. Feature -> Consequence Mineral oil-based silicon-free -> minimum risk of surface defects and loss of adhesion -> works in a wide range of waterborne systems Low viscosity -> easy handling Low emulsifiability in in water -> provides longterm effectivity -> decreased water sensitivity and increased scrub resistance DOSAGE It is recommended to add at least approx. half of the quantity of SERDAS GBR to the mill base formulation and the rest during the letdown stage. The exact concentration to be used depends on the individual conditions. In general a rate of 0.2 – 0.5% SERDAS GBR, calculated on the total quantity of the paint system, will give excellent results. Nonionic silicon free liquid defoamer with an excellent stability, recommended for water-based systems, such as emulsions, emulsion paints and water dilutable resin systems. Recommended for systems with good emulsifying properties, such as surfactant stabilised emulsions and emulsion paints. Coalesces minute air bubbles in the water phase, allowing them to rise and suppress foaming during the manufacture, the let-down-process, the canistering as well as during the application of the paint. Has excellent stability properties and can be stored for many months without the risk of separation of sedimentation. Mineral oil-based silicon-free, minimum risk of surface defects and loss of adhesion. Low viscosity, easy handling. Low emulsifiability in water, provides longterm effectivity, decreases water sensitivity and increases scrub resistance. Add at least approx. half of the quantity to the mill base formulation and the rest during the letdown stage. Recommended usage level: 0.2 – 0.5%, calculated on the total quantity of the paint system.
