Abstract: A manure, landfill leachate, sewage and/or wastewater treatment plant, treatment equipment or downstream conveying equipment, such as a manure, sewage and/or wastewater treatment plant comprising one or more biological treatment reactors, where said treatment plant or equipment comprises at least one component, wherein the at least one component and/or the at least one or more reactors or a drain of the treatment plant or equipment comprise at least one surface, which is exposed to a sus- pension comprising struvite particulates or colloids or to a supersaturated struvite so- lution, and where said reactor(s), pipes and/or said component is coated with a coat- ing, said coating being applied to at least a part of said surface exposed to the struvite containing suspension or supersaturated solution. The coating is preferably prepared using organosilanes. The coating is applied by a method comprising the steps of (i) preparing a liquid coating composition, (ii) applying said liquid coating composition to at least part of the surface of an article and (iii) curing to form solid coating film on said article. The coating reduces or eliminates formation of struvite deposits on the coated surface arising from a suspension of struvite particles or from a supersaturated struvite com- position.

Abstract: A curable coating composition and the use, especially in heat exchangers, for heating and/or cooling water, in particular tap water, is described. The curable coating comprises, based on solids after curing, 35-80% by weight of an epoxysilane according to the general structure 1 and/or its hydrolysation and/or condensation products, 1 : R 1 R 2 a SiR 3 b with R1 being 3-glycidyloxypropyl, R 2 being methyl, R 3 being alkyloxy or acyloxy, a being 0, 1 or 2 and b being 3 -a and 20 - 65% by weight of a blocked polyisocyanate and optionally further components. The coating provides improved corrosion protection on aluminium surfaces, reduces limescale formation on heat exchanger surfaces and is able to withstand lateral and/or temporal temperature gradients when coated on heat exchanging surfaces.
