Curing Aid : Curing adjuvant in aqueous dispersion for concretes

Curing Aid Curing adjuvant, based on special acrylic resins in aqueous dispersion; applied by spraying, on fresh concrete surfaces. It reduces the sudden loss of the mixing water by evaporation, thus contributing to the improvement of the general characteristics of the finished product. Unlike treatments based on wax or synthetic oils, Curing Aid is not a hydro-oleo repellent substance. Curing Aid bases its working principle on the cross-linking of a copolymer particularly similar to the constituents of cement-based mixes. The copolymer inhibits the evaporation of water and is chemically fixed with the support. Curing Aid, thanks to this polymerization process, is not a potentially detaching substance with respect to subsequent coating treatments, unlike the common anti-evaporating agents present on the market that base their effectiveness on active hydro-oil repellent substances. Aid for curing and curing measures in concrete conglomerates: industrial concrete floors, foundation slabs, massive jets, betons, thixotropic and castable structural mortars, fiber-reinforced micro-coals etc. Curing Aid must be applied to the surfaces of fresh mix, preferably by spraying, using low pressure sprayers. Curing Aid can also be rolled out but in this case it is advisable to wait for it starting phase and first surface hardening (losing part of its effectiveness). In case of particularly unfavorable exposure conditions (dry and / or windy environment) it may be necessary repeat the application. Curing Aid is not a hydro-oleo repellent substance. Curing Aid bases its operating principle on cross-linking of a copolymer with excellent stability under alkaline conditions, which inhibits water evaporation by chemically fixing with the support. Curing Aid, thanks to this process of polymerization and tenacious adhesion on the surfaces of the conglomerate, it is not a potentially detaching substance with respect to subsequent coating treatments. It is understood that an excess of mixing water in the concrete design mix, with an attached phenomenon of bleeding, it can affect correct Curing Aid polymerization and create a non-perfectly linked crosslinking with the support. Therefore it is always advisable to check the degree of compactness of the surfaces and, in case of doubt, proceed with an effective cleaning before carrying out any superficial painting. The operations of sanding, dust removal and in general of preliminary cleaning are, however, always recommended in all the codes of good practice concerning the painting and coating of industrial floors. The use of the curing adjuvant does not exempt from the adoption of normal protective measures, where necessary (covering products with sheets of polyethylene, in non-woven fabric, jute bags, prolonged wetting, etc.). It is not a pigmentation, after the application it is transparent. From 0.07 to 0.1 kg of Curing Aid per square metre of surface to be treated, based on the porosity and absorption of the surface itself. Packaging: 1000 kg tank UM: €/kg
