TYPE OF POWDER RESINS OFFERED IN 1999 BY SERGIO GAZZEA AS VIANOVA RESINS until 2003 UCB

Several types of resin systems offered including polyester-based and acrylic systems. Urethane acrylate and crystalline resins.

Resins developed for very specific applications such as wood, vinyl, metal etc. Urethane acrylate imparts outstanding smoothness, hardness, with improved scratch and chemical resistance.

Resins with high glass transition temperatures (Tg) that improve process ability and powder storage stability.

Crystalline resins improve coating characteristics such as mechanical perform, smoothness and adhesion without compromising process ability or lowering Tg.

Future Trends

“The automotive trim market should be interested in the concept of providing UV-powder coated parts, both metal and plastic to the OEMs.

The high gloss, crystal clarity, higher hardness and chemical resistance are a good match for this market.”

?“Future development trends will focus on reducing the melt and flow temperatures of the UV-powder coatings to open up new opportunities for powder. Development efforts will also support opportunities in specialized markets where the unique attributes of UV powders are a good fit. Specifically, UV powder research will continue to push the performance envelop as required by the market.”

·???????? 2024 Why low growth on UV powder coatings?

In my opinion we are waiting for someone to come along with a simple technology at the right cost, but managed by real experts who know the entire process from A to Z (from the chemistry of the binder system to the final characteristics of the applied film) to support the potential market with technical-economic knowledge and problem solving. I don't see anything new compared to what I had developed up to 25 years ago.

From what we are seeing, the most interesting developments are low-temperature curing systems for heat-sensitive substrates and UV curing systems.

Developments will be driven by the need to reduce energy demand, costs and carbon footprint.

Advances in enabling technologies, such as UV curing, are meeting lower energy demand requirements to broaden the variety of substrates that can be coated with powder.

Technology trends aside, I believe we will continue to see major investments in new capacity as manufacturers position themselves in the race to lead the transformation from liquid to solid systems.
