Development of a new coating system can be a complex process. Formulations are optimized to provide the required environmental performance as well as the desired physical appearance at a cost point suitable for the target market. Additionally, existing products may need to be reformulated for green product initiatives, cost reduction or new environmental regulations. With all of these demands on the development of coating systems, optimization of the development process is crucial for a coating manufacture’s success. New measurement technologies improve product development by providing greater information about a coating’s performance early in the development process.
This webinar will focus on the use of non-destructive, hand held FTIR instruments to monitor weathering and cure performance in coatings. Infrared spectroscopy has been used for many years to monitor UV degradation, hydrolysis and cure of multi-part coating systems. Conducting these measurements using novel non-destructive instruments allows for nearly continuous measurements throughout the performance evaluation. This allows for finer resolution and increased efficiency. Additionally, this portable technology can evaluate coating performance in real life situations, providing immediate, meaningful results. The presentation will contain both technical details demonstrating application to weathering and cure studies as well as case studies demonstrating the use of these measurements within the coating development process.

FEVE fluorinated resins have been used in the coatings market for over 30 years. Their excellent weatherability has given them a place in exterior coatings when the requirement is long term durability.
However, the original FEVE resin technology could not create formulations that met VOC regulations, so FEVE water-based emulsions were brought to the market. These emulsions, besides exhibiting great weatherability properties, have been found to improve additional properties such as water resistance, which can help increase resistance to mildew and dirt pick-up.
In addition to this lab work, testing has been done with blending solvent-based FEVE resins with lower molecular weight polyols to reduce VOC levels and improve specific properties.
This webinar will present the results of these new formulations and the subsequent lab work.

This webinar will introduce Dow Corning® 87 Additive and Dow Corning® 88 Additive in the architectural market. Both additives improve water repellency and provide improved water beading in decorative coatings, while Dow Corning® 88 Additive is a silane/siloxane blend that also imparts improved water repellency and prevents water absorption. Both additives create a hydrophobic silicone network in the paint that repels water but is permeable to water vapor coming from the substrate, leading to improved water repellency without cracking and blistering. These novel products are designed to provide sustainable solutions to a challenging problem in this market. Unlike other silicone-based materials, these new technologies are effective at low use levels. Register for this webinar to hear a Dow Corning expert elaborate more on this technology.
