Resimac is a manufacturer of epoxy and polyurethane materials and coatings. The business, based in Thirsk, North Yorkshire, has a reputation for providing quality, coating solutions within short time frames.
Recently, the company developed a unique solvent free coating product, which Itac has successfully helped to upscale and test, ready for commercial volume production.
The product is an anti-corrosive paint, which can withstand temperatures of up to 600 degrees centigrade, when applied to industrial pipework carrying super heated chemicals.
Resimac, following an enquiry from a world leading paint manufacturer, formulated the coating. Dr. Paul Battey, Resimac’s Chief Chemist, developed a moisture sensitive silicone system, which he laboratory tested, achieving highly favourable results. He then sought a manufacturing partner who had the requisite development and manufacturing capabilities to take the product forward. During initial discussions with Itac, a rapport soon developed once he found that Peter Curtis, an old friend and former colleague, was heading the in-house technical team.
Itac satisfied all Resimac’s requirements with its extensive silicone knowledge and production capacity. In recent months the company has successfully scaled up the laboratory formulation, providing Resimac with live, quality control production data, through its unique SPC system. Volume batches have been trialled and tested. The product is now ready for market.
Mathew McDonnell, Resimac MD, said, “Itac has a great team that we enjoy working with. We went in search of a manufacturing partner and discovered in Itac a flexible business, offering formulation and production support from start to finish. In addition to this project, we now have an expressed interest in Itac’s Delvemade specialist range of roofing and cladding coatings.”
Both companies are confident that this is just the start of a relationship that is set to grow.
Ever since China’s Terracotta Army was discovered in 1974 it has been thought that the Warriors weapons, many of which are bright and sharp, had been preserved by an advanced form of chromate conversion coating technology (CCC). This belief was supported by the detection of chromium traces on the surface of the weapons.
Professor Marcos Martinon-Torres led a team at University College London (UCL). They examined the weapons lacquer and soil from the site and conducted CCC and accelerated ageing. The results have shown that the surface chromium present is correlated with artefact type and uncorrelated with bronze preservation. The lacquering used extensively to cover the figures and wooden parts of weapons is rich in chromium.
Professor Martinon-Torres concluded that the chromium enrichment, detected on the surface, is not the consequence of a deliberate treatment, but a post depositional contamination. Also that the source of the chromium is lacquer, used throughout the site. The soil from the site is moderately alkaline ph with small particle size.
In summary, the lacquer, soil type and bronze composition, combined to lead to the remarkable preservation of weapons, which had laid undisturbed for over two millennia.
