Wayne Juda has worked in the coatings chemical industry for over thirty years. Over his career, he has worked as an R&D polymer chemist synthesizing resins involving Epoxy, Amine Curatives, Polyurethane, Solution Acrylic, Alkyd/Polyester, and UV curable technologies. His work focused on solvent-based and water-based systems used in the coatings and ink industries. Wayne is a Sr. R&D Chemist at Dystar working on additives and specialty coatings development for the Performance Chemicals Group.
Continued development of multifunctional silane technologies at DyStar has resulted in lower particle size and improved functionality such as block resistance and hardness of the coating film. Additionally, longer shelf stability can be realized. These novel formulations are synthesized utilizing emulsifiers that are closely related to the silanol backbone, improving the ease of synthesis of a lower particle size micelle that directly affect the stability. DyStar will present data demonstrating the differences in the original and novel versions of the multifunctional silanols in final coatings and sealant formulations. This technology should provide formulators of low/zero-VOC waterborne coatings a strategy for dealing with some of the problems inherent to low-Tg latex films.
