Speeding Up Quest for Sustainability

— Prof. Long Lin

Sustainability has necessarily become an increasingly important topic of concern for most, if not all, industries. So, it is not surprising that sustainability features highly on CHINACOAT2018’s agenda. Indeed, sustainability is the theme that underpins both the Conference (taking place on 3rd and 4th December) and the Technical Workshops (to be delivered on 4th and 5th December) at CHINACOAT2018 that will be showcased at the China Import and Export Fair Complex (Canton Fair Complex), Guangzhou early next month.

 

Multifunctional Additives

Microfibrillated Cellulose: Multifunctional Additive for Waterborne Coatings

— Dr. Otto Soidinsalo, Synnøve Holtan, Ali Moosavifar & Justin Scarpello, Borregaard, Norway

The change from solvent borne systems to waterborne systems is causing challenges for the formulators. The shift to waterborne systems is not always straightforward and often new technologies are needed in order to obtain the same performance as with solvent borne systems.

 

Weatherability / Durability

Waterborne PVDF Coatings Technology to Address the New Environmental Regulation in China

— Dr. An Du, Arkema Inc., USA

Polyvinylidene fluoride (PVDF) is well-known in coatings applications for its excellent weatherability, durability and chemical resistance. This paper focuses on the innovation of waterborne Kynar® PVDF resins invented by Arkema. The waterborne technology is proven to have similar weatherability and durability performance to the traditional Kynar 500® FSF® solvent-based technology. It is produced by a fluorosurfactant-free process and can be used on metal substrates with a similar application condition as solvent-based Kynar 500® FSF® coatings.

 

Surfactants

Leveraging Surfactant Structure: Property Relationships to Address Emerging Needs in Coatings

— Christine Louis and K. Michael Peck, Evonik Resource Efficiency

All surfactants are amphiphilic molecules that orient at interfaces; however, a surfactant’s exact chemical structure will dictate its behaviour at these interfaces. In dilute systems, this is well understood, but in the complex formulation of most coatings applications the behaviour becomes far more difficult to predict.

 

Powder Coatings

Advances in Electrostatic Coating of Non-Conductive Substrates: Wet Painting & Powder Coatings (Part 1)

— W.S. Gutowski, S.Li, L.Russell, C.Filippou, Mark Spicer, CSIRO Manufacturing Flagship, Australia

Our earlier paper on powder coating heat-sensitive substrates presented broad details of our technology converting surfaces of non-conductive plastics into materials exhibiting good surface conductivity. This development overcame preexisting technology barriers such as the lack of polymer surface conductivity and poor adhesion preventing the use of electrostatic transfer of coatings, such as powder resins, in surface finishing of non-conductive materials including plastics, polymeric composites or wood-based products.
