The understanding of water and the proper usage of water in new accelerated weathering cycles will greatly improve the confidence level of preventing coating defects in the future.
A newly developed, one-component waterborne polyurethane dispersion (PUD) topcoat, with VOC below 200 g/L, offers exterior durability, color and gloss retention, and chemical resistance comparable to two-component solventborne and waterborne polyurethane coatings.
Successful incorporation of nanometric aluminum oxide particles into UV-cured coating formulations for improved scratch resistance requires adherence to a three-step process.
This study aims to elucidate the influence of select hydrophobic monomers on the physical and chemical properties of binders, and ultimately on the overall performance of exterior wood coatings derived from such combinations.
It is still possible to generate innovative color effects for coating, plastic and ink applications using existing, established organic pigment chromophores.
In this study, APEO-free alternatives provide emulsification during the polymerization equal to the industrial standard, NPE ether sulfate, as a “drop in” replacement.
