Surfacing Science Seminars

The session will address the challenges facing chemical and coating manufacturers: increasing energy efficiency and use of renewable energy; reducing reliance on fossil-based feedstocks for materials; and improving recyclability of products and packaging.

A discussion on the benefits of bio-based solvents and the commensurate risks with regards to spill clean and disposal.

Graphene is a unique form of carbon that has extraordinary barrier properties as well as excellent thermal conductivity, strength, flex and other attributes that contribute to significantly improved coatings. This session will share what graphene is, the different types of graphene that are commercially available, and how using extremely small amounts of graphene in a matrix can drive step change improvements in coating systems.

The most in-demand pigment used in paints and coatings is TiO2; any improvements to its substantial environmental footprint are to be welcomed. PRA has developed technology for the recovery of TiO2 from mixed waste paint, providing a product with properties comparable to virgin product. Our industrial research project, in collaboration with Crown Paints, with support from Innovate UK, has taken this technology from the bench to pilot-scale processing. A circular economy approach to TiO2 manufacture, addressing the substantial environmental burden of waste paint and presenting an opportunity to recover valuable materials will provide significant benefits for sustainability and cost reduction.

Paul Sheppard will open the presentation by listing the various regulatory pressures and coatings industry specific chemicals that are affected. Con McElroy will follow this by discussing safer and greener alternatives to restricted dipolar aprotic solvents used during the process for recycling Lithium-Ion batteries. Graham Armstrong will finish the session by discussing Chrome free alternatives to the REACH Authorised substance Chromium Trioxide traditionally used in inorganic coatings for corrosion protection of compressor blades in  aeroengine and industrial gas turbines..
