Abstract
The invention relates to a substrate intended in use to contact a fouling agent, the substrate including a coating comprising polysaccharide, which coating serves to reduce or prevent fouling of the substrate caused by contact from the fouling agent, in comparison to an equivalent uncoated substrate. The invention also relates to the anti-fouling coating, to apparatus comprising such coating and to related methods of reducing or preventing fouling of a substrate intended in use to contact a fouling agent.
Claims9
A heat exchanger or production line apparatus comprising a metal or metal alloy substrate on an internal surface thereof intended in use to contact a fouling agent, said substrate including a coating comprising polysaccharide and protein bound to the polysaccharide wherein the polysaccharide comprises dextrin starch and octenyl succinic anhydride starch and the protein comprises casein, which coating serves to reduce or prevent fouling of the substrate caused by contact from the fouling agent, in comparison to an equivalent uncoated substrate.
A method of reducing or preventing fouling of a metal or metal alloy substrate intended in use to contact a fouling agent, in comparison to an equivalent untreated substrate, which comprises treating the substrate with aqueous polysaccharide to produce a polysaccharide comprising coating on the substrate, further comprising treating the polysaccharide coated substrate with an aqueous mixture, dispersion or solution of protein, wherein the polysaccharide comprises dextrin starch and octenyl succinic anhydride starch and the protein comprises casein;
- wherein said substrate is a component of a heat exchanger or an internal surface of production line apparatus.
