This product has an equivalent weight of approx. 315, a flash point of approx. 5°C, and a density at 20°C of approx. 1.17g/ml. Systems crosslinked with Desmodur® L 75 can be used as coatings for furniture, parquet flooring, metal, paper, plastics and mineral substrates. Desmodur® L 75 is also suitable for room-temperature crosslinking of adhesives based on Desmocoll® or Baycoll®. These can be used to bond many materials, e.g. wood, metal and plastic. The use of this polyisocyanate increases the resistance of the bonds to heat, oil, plasticisers and many solvents. It ensures good adhesion to many materials, especially plastics. view less | |
