Solubility / thinnability Generally speaking, Bayhydur® 401-60 PGDA can be diluted with different
polar to unpolar aliphatic solvents that are common when formulating lacquers. With polar solvents dilution of down to 20 % solid content can be reached. The storage stability of the corresponding dilutions needs to be checked, thoroughly. Especially, when using benzines dilutions need to
be done with due care and skill. The addition of Bayhydur® 401-60 PGDA to the benzine-dissolved binder is recommended. Only PU grade solvents (< 0.05 % water) should be used. Also, the solvents have to be free off reactive groups such as hydroxyl or amino groups.
Compatibility Generally speaking, Bayhydur® 401-60 PGDA can be mixed with various Desmodur® - and Bayhydur® - types, e.g. Desmodur® N 3300 or N 3600, Bayhydur® 3100, XP 2655 or XP 2547. However, the compatibility must be tested in each case. As well, Bayhydur® 401-60 PGDA can be dispersed in
various waterborne binders such as Bayhydrol® - types, e.g. Bayhydrol® A 2470, A 2646, A 242, A 2845 and U 2755. The overall formulation (solids content, co-solvent content, type of co-solvent) needs to be considered in order to achieve a stable and properly working formulation.
