The COOE polymer research team in collaboration with University of South Australia developed an epoxy resin made from renewable resources. The bio-epoxy resin can be made using waste products from the bio-fuel industry, making this bio-epoxy resin a truly “green” resin. The product is currently being commercialised by our R&D client Change Climate and sold as CCBE1 and CCBE5.
Beautiful chemistry! CCBE has no nasty smells, so there is no need to evacuate the building while applying the product, and amazingly the bio-epoxy sets very hard and clear. The photograph shows an exposed aggregate concrete floor sealed with the bio-epoxy and reflecting the outside lights. The owner of the house is a reputable building designer who bought the very first commercial batch in 2016.
This resin has exceptional properties; in most cases it is superior to current petroleum based epoxy resins without some of the “nasties” such as the bis-phenols (BPA’s) in traditional epoxy resins and no added solvents.
Change Climate Bio-Epoxy has low VOC (no added solvents) and low odour (no bis-pheonols) and yet demonstrates superior strength (77 MPa to 98 MPa with fillers) and UV resistance transparency (48 hour intensive exposure test). Clear as glass!
Various fillers, additives and dies have been tested with the Bio-Epoxy resin and applied as a thin coating on timber, canvas, silica molds, metal and concrete. The tests conducted by COOE show great application opportunities that take advantage of its hardness, adhesive strength, non-yellowing property, resistance to UV, low odour and its green credentials. Change Climate is responsible for the commercialisation and further product development.
Some potential applications for bio-epoxy resins:
- Building Industry: As a sealant or floor cover, feature finishes either in the coloured or clear form, building materials and adhesives.
- Manufacturing Industry: In fibreglass products such as marine craft, rainwater tanks; in plastics for car light or traffic light lenses; electrical circuit boards.
- Art Supplies: As a resin to imitate glass, can be used for moldings, inclusions & laminates.
- DIY: A broad range of products from adhesives to water repelling sealants, feature finishes, and numerous hobbies.
