The latest technical highlights in the European Journal of Coatings describe how bio-based chlorol can be used to reduce the carbon footprint of epoxy coatings.
epoxy resins are widely used as adhesives in protective coatings because of their excellent adhesion and corrosion resistance after curing, formulation flexibility and commercial availability. Traditionally, alkaline epoxy resins have been prepared by ECH and Bisphenol A (BPA), both of which are usually derived from petroleum
from
.
this technical paper describes renewable glycera (a by-product of vegetable oil conversion) that has proven to be a reliable raw material for 100% bio-based ECH production on an industrial scale. According to the paper, the use of bio-based chlorinol can reduce the carbon footprint of the coating by up to 61%.
an epoxy formula with 100% bio-based carbon content?
paper further describes possible ways to develop coatings with a longer number of bio-based components. For example, replace curing agents (all or part) with 100% bio-based equivalent molecules, such as aromatic amines derived from cashew shell oil (CNSL) or converted from petroleum-based solvents such as xylene to alternatives derived from renewable raw materials with similar solubility capabilities.
