bayhydur 401-60 pgda water-based pu curing agent weather and chemical resistance

product features
a hydrophilic modified aliphatic polyisocyanate based on isophorone diisocyanate (ipdi), bayhydur® 401-60 pgda can be used as a co-reactant in water-based resins and in the preparation of resistant curing agents for chemical and weather-resistant coatings

form of supply
about 60% propylene glycol diethyl ester solution

other data**

**this data is general information.

solubility/dilution
generally speaking, bayhydur® 401-60 pgda can be diluted with a variety of polar to non-polar aliphatic solvents and is commonly used in formulated paints. can be diluted with polar solvents to 20% solid content. the storage stability of the diluent must be thoroughly tested, especially when using gasoline-based diluents and this needs to be done with care and skill. it is recommended to add bayhydur® 401-60 pgda to gasoline-soluble adhesives. only use polyurethane grade solvents (less than 0.05% water content). the solvent cannot contain reactive groups such as hydroxyl or amino groups.

compatibility
generally speaking, bayhydur® 401-60 pgda can be mixed with various desmodur® and bayhydur® types, such as desmodur® n3300 or n3600, bayhydur® 3100, xp 2655 or xp 2547.
​ ​ however, compatibility must be tested in every case. at the same time, bayhydur® 401-60 pgda can be dispersed in various water-based adhesives such as bayhydrol® types, such as bayhydrol® a2470, a2646, a242, a2845 and u2755.
the overall formulation (solids content, co-solvent content, type of co-solvent) needs to be considered to achieve a stable and appropriate working formulation.
​ ​ ​ if you require technical support, please ask your supplier.

features/applications
bayhydur® 401-60 pgda is easily emulsified in the water phase to form water-based paint or adhesive, and is mainly used as a co-crosslinking agent for bayhydrol® arranged water-based resins.
by adding bayhydur® 401-60 pgda to the hdi-based bayhydur crosslinker, the coating properties of two-component polyurethane coatings such as bayhydur®
a typical mixture of bayhydur® 401-60 pgda and the hdi-based bayhydur crosslinkers described above contains 5-30% bayhydur® 401-60 pgda in the total solids of the crosslinker.
the advantages of bayhydur® 401-60 pgda are as follows:
final performance, such as
• increased surface hardness;
• increased chemical resistance and solvent resistance.
application performance, such as
• significantly longer pot life, even at high processing temperatures;
• dry faster;
• improved robustness, including increased bubble-free layer thickness.
