Speaker: Graham Howarth, Technical Director, Arropol Chemicals, 1815 S Hamilton Street, Dalton, GA 30720


Title:  Using recovered carpet from California landfill to make useful CASE application materials


Abstract: The world is moving on and recovering and recycling or use of renewable raw materials is becoming more fashionable especially in California and Europe. A key raw material for Carpet is PET polyester. Virtually all post-consumer/industrial carpet has gone into landfill. The state of California imposes a tax on this. This presentation gives a view of past, present and future technology to recover carpet and turn it into useful CASE application raw materials. Some brief chemistry and manufacturing as well as the recovery process is discussed. Examples of the design of various products made from this material will be presented.  Modification of these systems to produce hybrids is also discussed. A brief discussion will also take place on other polyurethane and epoxy chemistry products.


Bio: Graham A. Howarth graduated with Majors in Chemistry and Material Science and Engineering and minors in Technology and mathematics. He also has a Master of Science and Diploma in “The Corrosion of Engineering Materials” from Imperial College London and awarded student of the year prize. His thesis subject was “The design of Waterbased Epoxy and High Solids PU/Oxazolidine Coatings for corrosion protection”. He has been a guest lecturer there on the MS course. He is a Chartered Scientist, Chartered Chemist, Fellow of the Royal Society of Chemistry and a Technical Editor of JCT+R and a member of the Editorial Management Board. After 9 years at Akzo Nobel Coatings, 11 years at Industrial Copolymers and two years at Tetrosyl Automotive Coatings, he moved to the USA in 2000 and spent 10 years at Arnette Polymers and a year at Cornerstone Flooring and then 6 years at Dayton Superior Corporation. He now works for Arropol Chemicals in Dalton, GA. He has written numerous journal articles and given presentations and seminars around the world.

Title: A New Approach for Preventing the Microbial Defacement of Coated Surfaces


Abstract: In today’s globalized coatings market there is free movement of raw materials and technology across international borders. This globalization has provided benefits, however as global supply chains become interconnected and interdependent there is greater potential for disruption from regional regulatory changes. While these can affect any raw material, antimicrobials (biocides) pose a unique challenge to formulators, as they are often subject to obscure regulatory provisions.


Microbial defacement represents a risk and a potential expense for manufacturers of any material susceptible to microbial defacement in the dry state. This paper describes a novel formulation approach used to create a more multi-functional dry film preservative system for use in coatings, adhesives, sealants, and other construction materials. This innovative approach provides a broad-spectrum protection system, with the additional benefit of being more robust against future regulatory changes. Supporting data and examples are provided from regions where this new technology has already been commercialized.


Bio: Scott Brown leads Lonza’s Materials Protection Global Applications Technology group. This group is responsible for providing applications support for existing biocide products of the Materials Protection business, and for guiding the development effort for new biocide products.
