It is used as a binder for physically drying primers and finishes for plastics. This product has a non-volatile content (1g/1h/125°C) of 40 ± 1%, a viscosity at 23°C of 7,500 ± 1,500 mPa·s, a hazen color value of ≤ 150, a density at 20°C of approx. 0,94g/ml, and a flash point of approx. 22°C. Pigment preparations such as Bayderm® Colours B-TO and C-TO (Bayer) are recommended for colouring formulations. It is also possible to use standard pigments or pigment/extender combinations. 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. voir moins |
