This product has an equivalent weight of approx. 250, a flash point of approx. 217°C, and a density at 20°C of approx. 1.13g/ml. Desmodur® MT reacts with water to release carbon dioxide. It serves as a dewatering agent to ensure the storage stability of moisture-curing pigmented one-component polyurethane coatings. The stoichiometric conversion of 1g of water requires approx. 28 g of Desmodur® MT. Trials and experience have shown that the best results are obtained using two or three times this amount. The reactivity of Desmodur® MT with water is comparable with the reactivity of the Desmodur® E grades. verkürzen | |

It is a solvent-free, dark brown liquid of low viscosity at temperatures above 10°C that may partially crystallize at lower temperatures. This product has a pot life of 25-35 min., a phenyl isocyanate content of max. 50mg/kg, and a vapor pressure at 20°C (MDI) < 10^-5 hPa. Desmodur® VK 5 can be combined with Baycoll in the formulation of adhesives for bonding many materials, e.g. wood, metal and plastics. Desmodur® VK 5 is particularly suitable for combining with Baycoll in the formulation of reactive two-component adhesives and moisture-curing one-component adhesives. On account of the high vapor pressure of Desmodur® VK 5, adhesives with free isocyanate groups can only be handled in work areas with adequate extraction. verkürzen | |
