It is a solvent-free, colourless to yellowish liquid of medium viscosity at temperatures above 20°C that crystallises at lower temperatures. This product has an NCO content of 23.0 ± 0.5%, a viscosity at 25°C of 600 ± 100 mPa·s, a hydrolysable chlorine (Cl) amount of max. 50mg/kg, and a density at 25°C of approx. 1.21g/cm^3. Desmodur® PF can be combined with Desmophen®, Baycoll® or Acclaim® in the formulation of adhesives for bonding many materials, e.g. wood, metal and plastics. Desmodur® PF is particularly suitable for combining with Baycoll® in the formulation of reactive two-component adhesives and moisture-curing one-component adhesives. view less | |

It is a brown, solvent-free liquid with a low viscosity (25°C) of 90 ± 20 mPa·s. This product has an NCO of 31.5 ± 0.5%, a flash point of approx. 229°C, and an equivalent weight of approx. 133. Desmodur® VL is combined with, for example, Desmophen® 1145, 1150, 1155, 5028 GT and 1380 BT. Depending on the Desmophen® product used, the coatings yielded can be varied from hard to flexible. It is necessary to add water scavengers such as molecular sieve paste® 3 Å to the polyol component to prevent the undesired reaction of Desmodur® VL with water. Systems formulated with Desmodur® VL are suitable for coating concrete, asphalt, fibrous cement and plastics. view less | |
