Protective Coatings

Generally, water based protective coatings are more permeable to gases and water vapour. These coatings are formulated by using polymer dispersions. Water vapour permeability is a desirable property to allow water vapour to escape from the substrate. But, if the permeability is too high, carbon dioxide can diffuse from atmosphere into the substrate easily. Hence there is a need for coatings with moderate gas permeability which can prevent Carbon dioxide from diffusing into the substrate while allowing moisture to escape.

Protective coatings are formulated to prevent the diffusion of Carbon dioxide and thereby protect concrete structures from the detrimental effects, carbonation.

Products such as Tammscoat, T-Guard, Adhere and MuCis PROTEZIONE are highly efficient.
