Some types of PU Paint

  1. 1K - PU Paint

1K-PU is a solvent-borne PU-based primer with a single component. The solvent evaporates after treatment, and the residual chemical crosslinks by absorbing moisture from the air and, in the case of a concrete surface, from the surface. 1K-PU is developed to soften and prepare old coatings before over-treating them with new layers. It is also an excellent primer for blast steel surfaces not susceptible to high-temperature submersion applications. 

It’s suitable for both outdoor and indoor decoration. It dries and cures quickly, resulting in minimal downtime and related losses. It’s just as simple to apply as epoxy, but PU has a quicker return-to-service time.
