|||||||||||||||
AVCO-ANTIFOAM R-140 is a concentrated anti-foaming agent suitable for all textile preparation, dyeing and finishing processes. AVCO-ANTIFOAM R-140prevents and destroys foam in all water phase treatments of fibers, yarns and fabrics. AVCO-ANTIFOAM R-140 can be used in baths from acid to alkaline pH values. AVCO-ANTIFOAM R-140is compatible with a wide range of dyestuffs, detergents and additives used in pretreatment, dyeing and finishing processes. AVCO-ANTIFOAM R-140is stable in cold and hot baths, and there is no emulsion break-down when used in jets or circulating machines. By its de-aerating effect the product improves the running properties of fabric ropes in jet machines. SPECIFICATIONS:
PROPERTIES & USES: 1. Very efficient and economic anti-foam. 2. Can be used in many types of textile aqueous operations. 3. Good stability to high temperatures up to 130°C. 4. Good stability to high shearing machines with a long lasting de-foaming effect. 5. Stable in a wide range of pH values (2-12). 6. AVCO-ANTIFOAM R-140 is a liquid product which can be dosed very easily into the aqueous phase. AVCO-ANTIFOAM R-140 spreads in the aqueous medium very quickly, and its anti-foaming effect shows up immediately. APPLICATION To achieve rapid dilution and thus maximum effectiveness and economic use, AVCO-ANTIFOAM R-140 should be diluted with 3 – 5 parts of cold water before adding to the dyeing or finishing machine. Dilution should be made by simple stirring with a rod, pour product into the water while stirring. For an optimum effect it is important to add AVCO-ANTIFOAM R-140 separately to the liquor. Avoid mixing the concentrated antifoam with other chemicals in the side tank or in the weighing device. The recommended dosage is 0.1 – 0.5 g/l. The stock solution of the pre-dissolved product should be gently stirred before using. Generally, a stock solution is prepared for one working day. |
