In-Can Protection

Ready mixed gypsum plaster products and primers need to be preserved against decay during storage before application. This is called "in-can preservation". In-can preservation of aqueous products may be achieved with a variety of different biocidal products. The choice is determined by compatibility, efficacy, price, labelling, plant hygiene, regulatory situation and availability in different parts of the world.
