摘要: Melamine incorporation in hybrid polyurethane/acrylic dispersionsMelamine increased the water resistanceMelamine provoked the formation of a carbonaceous char when heatingGood adhesion, and reduced water sensitivity transparent coatings for wood could be formulated....
This underscores the need for superior protective coatings able to resist such degradation while retaining their icephobic properties. Polyurethane (PU) coatings are a desirable choice as a polymer-based material for protecting metal surfaces against severe conditions [24], [25]. Recent studies have ...
Some organic pigments may catalytically accelerate the curing reaction of polyurethanes. This is due to their metal content. Some organic pigments will not give enough coverage in single-coat applications. This is due to transparency. There are several conventional extenders for one- and two-component...

Another key intermediate is based on the abil- ity of polyether diols to be modified by metallation reactions at one hydroxyl end group.26 Thus, the re- action of poly(tetramethylene oxide) diol of average molecular weight 1000 or 650 with sodium hydride (2 equiv. OH groups to 1 equiv....
