Waterborne polyurethanes 总被引:28,自引:0,他引:28
Karl-Ludwig Noble 《Progress in Organic Coatings》1997,32(1-4):131-136
A major change in coatings technology was caused by the restrictions on volatile organic compounds (VOC) in coatings. These government regulations combined with performance advantages were the key to the success of waterborne polyurethanes. The production and chemistry of waterborne one-component polyurethanes and reactive two-component systems are discussed. Examples for their application, predominantly in the field of surface coatings, are given. 相似文献

Waterborne acrylic-epoxy coatings 总被引:2,自引:0,他引:2

Waterborne two-component acrylic-epoxy coatings are gaining popularity as topcoats in moderate duty industrial and high performance
architectural (HIPAC) applications. This increased popularity is due to their attractive handling, application, and performance
properties, along with their low solvent content and odor. The objectives of this work were to characterize the cure and property
development of these coatings, evaluate performance properties of cured films, and investigate a new epoxy resin dispersion
in existing acrylic-epoxy formulations. These evaluations confirmed that existing acrylic-epoxy coatings have long pot life
and short dry times while displaying a range of chemical resistance and physical properties. IR spectroscopy and differential
scanning calorimetry (DSC) results indicated that the extent of cure at ambient conditions over a 21-day period was minimal;
however, dynamic mechanical analysis (DMA) and solvent swell results did illustrate noticeable crosslink density development
under these conditions. DSC results demonstrated more complete reaction and cure after heating. Direct substitution of a novel
epoxy resin dispersion into these formulas resulted in lower required solvent content, shorter dry time, higher gloss, higher
crosslink density, and improved water and scrub resistance.
