Desmodur L 75
Solubility / thinnability 
In general, Desmodur L 75 has good compatibility with esters such as ethyl acetate, butyl acetate and 1 methoxypropylacetate-2 and aromatic hydrocarbons such as toluene, xylene, Solvesso™ 100 and ShellSol™ A. However, the solutions formed must be tested for their storage stability. The product is not compatible with aliphatics. Alcohols react with Desmodur L 75 and therefore cannot be used.
Prolonged storage of a solution with low binder content may result in turbidity and sedimentation.
Only PU grade solvents should be used (< 0.05% water). The solvent should not contain reactive groups.

Compatibility
 In general, Desmodur L 75 is compatible with many polyesters, polyethers and polyacrylates, as well as with other Desmodur grades.

Properties / Applications 
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. The pale inherent color of Desmodur L 75 permits its use in bonding transparent plastic films for packaging.
As with any product, use of Desmodur L 75 in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability. 

Handling information 
This product contains reactive TDI polyisocyanate/prepolymer and/or monomeric TDI and should only be handled using appropriate protective measures.
