Biobased Resin Technology: Helping Define High Performance aterborne technology continues to be the prime focus of emerging coatings markets while the attributes required for designation of a “green” coating continue to adapt. With more options available to achieve high-performance products, green has come to identify with resins that are low VOC, low odor and alkylphenol ethoxylate (APE) free. However, as the coatings market continues to expand, it is becoming more difficult to differentiate from competitors that offer similar product lines. ased on this, more companies are adding and/or B...

with for the coatings industry are focused on chemical exemptions, VOC limits, performance requirements and packaging constraints. Today, several independent green certification processes such as Green Seal® and Green Guard® are well established, with strict environmental components. A variety of products are available that conform to these requirements but, moving forward, are there other considerations that should be accounted for that distinguish one product from another and provide the manufacturer with a market advantage? he USDA BioPreferred® Program is a recent option T for product...

Alkyd latex: Low MW and exible polymer chain Alkyd latex: Low MW and exible polymer chain Alkyds have dominated the coatings market for many years because of their good overall performance, ease of application and low cost. They can be used in a variety of architectural and industrial applications. However, because traditional alkyds were available in organic vehicles, the need for lower-VOC coatings challenged researchers to develop alkyd-based systems with equivalent properties to high-VOC materials. igh-solids alkyds encompassed traditional alkyd H chemistry at lower initial molecular...

available solventborne, the highest performing commercially available non-biobased waterborne and the new biobased waterborne alkyd on different substrates, while Table 1 provides a summary of the performance data. Based on this testing protocol, the data demonstrates that BECKOSOL AQ 521 sealer at ~70 g/L performs closely to the solventborne control, which is well over VOC limits at over 700 g/L. A very key piece of information in the adhesion test was the improved wet adhesion of the biobased waterborne option over both commercial controls. The new biobased wet-look sealer was the only...
