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. voir moins
