Suds suppressors CUBD-WB

CUBD-WB (suds suppressors) use of one, traits: colorless to pale yellow liquid with special smell, the density of 0.96 g / cc and a viscosity 2.8mPa.s. Slightly soluble in water, soluble in ethanol, acetone, and other solvents, and with polyether polyols, polyester polyols, such as good solubility. Second, the characteristics and uses: This product is mainly used as a two-component or trace moisture component polyurethane elastomer sealants and coatings and acid scavengers, when the polyurethane system or trace moisture in the air and acids (≤ 0.5%), the molecule-specific active functional groups preferentially react with water to generate a similar structure polyol and isocyanate then reacts product can greatly improve the polyurethane material with a variety of surface particularly polar surfaces (such as aluminum, iron and steel, glass, cement, etc.) bonding strength, and greatly reduces shrinkage polyurethane material itself (such as high hardness polyurethane hardness is more effective than 60D). By adding CUBD-WB not only solved the polyurethane sealants and coatings industry, blistering, cracking, pinholes, distinctness of image, up barrels, thick coatings and other issues, even take to reduce the shrinkage of polyurethane, greatly improving the sealant and paint adhesion to the substrate. Third, the use recommendations: CUBD-WB added the timing of the recommendations in the final process polyurethane sealant added before packaging and stir evenly; if it is a two-component polyurethane, proposes to add polyol (non-isocyanate component); if it is a one-component polyurethane , can be directly added. Because CUBD-WB gentle reaction with water at room temperature, so in addition to water and enhance adhesion to generally 4-12h effect is obvious, such as with CUCAT-HS can shorten the onset time. Usage, as the case may be, the recommended dosage is 1-5%. Because CUBD-WB with water and acids will produce a chemical reaction, it should pay attention to the closed, after opening must be immediately sealed. Fourth, packaging and storage: Size: 25 / 200kg / barrel. Store in a cool dry and ventilated the warehouse to avoid sources of ignition, avoid sunlight. CUBD-WB on the skin and the respiratory tract have a stimulating effect, but less toxic, the use of such contaminated skin with plenty of water rinse, serious medical treatment. Quality assurance for one year (unopened). Please note must be sealed.
