The solvent resistance of films based on Desmolac® 4340 X/iB can be greatly improved by the addition of Desmodur® N 75 (10 to 20 %, calculated on the solid resin). This will result in post-crosslinking of the film with atmospheric moisture after 1 to 2 weeks. However, Desmodur® N 75 should not be added until just before application of the coating to prevent reaction with the isobutanol in the solvent mixture of the supply form. view less | |
