About Preschem
Preschem was founded by Chris McEvoy and Chen-Woo Chin, both experienced scientists who formerly worked for Australia’s pre-eminent scientific research organisation, the CSIRO. Together, they have more than 30 years of scientific, technical and industrial experience in wood preservation and research, publishing numerous technical papers in Australia and overseas.Since 1988, Preschem has grown to become Australia’s leading manufacturer of timber preservatives and exterior finishes. Our preservative products help extend timber life by preventing decay and wood rot and our exterior finishes are formulated to protect and enhance the natural beauty of timber. All of Preschem’s products are designed for maximum performance in Australia’s extreme climatic conditions.
Preschem takes a considered approach in the development, manufacture and end use of its products. Formulations must be environmentally responsible and safe to use. This is irrespective of whether they’re for industry or a home handyman. In order to achieve this, ingredients are carefully chosen to be effective and safe. In addition, they also must have minimal environmental impact. Preschem’s production processes are designed around the same philosophy. Our manufacturing systems incorporate closed loop recycling of waste materials.
Since 2000, Preschem has focused on export markets in the southern hemisphere – especially pole preservatives where energy utilities use Eucalyptus species for power poles. Preschem’s timber preservatives have a proven track record on three continents: Australia, Southern Africa and South America.
