Water thinnable white two-pack PU topcoat, based on Bayhydrol A 145

This formulation describes an industrial coating, specifically a water-thinnable white two-pack polyurethane (PU) topcoat. It's designed based on Bayhydrol A 145 and Bayhydur 304.

The formulation includes two components:

Component 1 contains Bayhydrol A 145, which is a waterborne polyurethane dispersion, along with other additives like surfactants (Surfynol 104 E), extenders (Sachtleben R-KB-4), water, and various thixotropic agents (Borchi® Gel THIX 921, Borchi® Gol LA 50, Borchi® Gol LA 200). The total weight of Component 1 is 85.20.

Component 2 contains Bayhydur 304, which is likely a polyisocyanate crosslinker. Its weight is 14.80.

The two components are combined to form a two-pack system. Water is added for thinning to adjust the spray viscosity.

The formulation also provides technical data such as the NCO: OH ratio, spray viscosity, pendulum hardness, and haze/gloss measurements. It emphasizes that each customer's use may differ and advises testing and responsibility for specific use. Additionally, it lists the suppliers of the raw materials used in the formulation.
