CoatMasters as hidden defenders in protecting construction materials
CoatMasters products are composed of environmentally friendly silicon emulsions designed for long term protection of construction materials against the destructive impacts of humidity, water penetration and chloride ions. This new waterborne emulsion formulations can now perform extremely well as traditional solventborne impregnants.
Humidity and dampness are the main reasons for various forms of damage and unsightly appearance in buildings. The porous structure of different mineral construction materials gives them a high sensitivity towards water absorption. The destructive effects of freeze-thaw changes, erosion of the structure and micro-organisms which prosper in humid environments are well understood phenomena. The erosion of reinforcing steels in concrete construction can also be attributed to the corrosive effects of absorbed water, and may require expensive renovation. Effloresence, washing out of lime and the growth of mosses, fungi, and algae all occur on wet surfaces. Finally, the thermal insulation of masonry is impaired under this wet conditions.
Benefits of using CoatMasters impregnation coating materials in construction.
Whether in new building construction, reconstruction or renovation, the water resistance of a building should not be left as the last taks of planners, businessmen and clients in defending against the financial losses caused by water damage. Chemistry plays an important role in "architectural protection" and should be to the forefront of every strategy for blocking water ingress. Hydrophobic silicones in particular have proved through more than 40 years of use to be highly effective in creating humidity barriers in building materials. The effectiveness of CoatMasters silicon emsulsion products as admixture and as an impregnating coating provides several or all of the following benefits.
- High water repellancy
- Excellent vapour permeability
- Reduced salt transmission and chloride ion penetration
- Good alkali resistance
- Good penetration
- Unchanged substance appearance
- Long term effectiveness
- VOC (volatile organic component) compliant
- Environmentally friendly
Environmentally and Regulatory compliant water based emulsions.
Growing environmental conciousness and official regulations demands low VOC or no-VOC on various types of coatings in general. CoatMasters impregnating products are designed to have very low VOC's, which very well meets Rule 1113 of the South Coast Air Quality Management Districts requirement for Waterproofing Concrete / Masonry Sealers of 100 grams/liter maximum which took effect on July 1, 2006
The use of CoatMasters admixture as an integral part of any cementitous composition totally eliminates the need for any VOC related add-on coating sealer materials when integrated in the fabrication of any type of concrete material.
