3 Total Floor Coating System Single / DoubleBroadcast SystemSelf- leveling SystemADBCADPrimer (A)–Often used with broadcast systems, and are highly recommended for any application on concrete (including damp/green). Can be pigmented if no base coat is used.Base coat or Mid coat – Self-level slurry (B) (50-60 mil dry); unfilled clear for single/double broadcast (C) (10-20 mil dry) or coating (5-10 mil dry).Top coat or Seal coat (D)– Applied as a clear coat on top of base or mid coat (10-20 mil dry).To combat the weaknesses of concrete a coating or flooring is applied to it. In this talk we will discuss a total flooring system that starts with a primer. Primers or sealers are highly recommended for any application onto concrete especially damp or green concrete. This is then followed by a base coat which can be a thin coating or a thicker floor. The base coat is then followed by a clear top coat to provide the ultimate in performance properties.
4 Attributes of a Total Floor Coating System Great Handling PropertiesLong working timeRapid property development“Green”Environmentally friendlyZero to low VOCLow odorExcellent Performance PropertiesGood adhesion to concrete (dry and damp)Good recoatabilityFast return to serviceUV stabilityChemical / stain resistanceImpact resistanceAbrasion resistanceSome of the advantages of using our total floor system are listed on this slide. Just to point out a few of them are that although you would be applying multiple coats you still have very fast return to service with our combined systems and Shafiq will go through exact timing in more detail later. Also you can have very short or very long recoat time depending on the needs of your customer. And of course by using these two systems you will achieve the ultimate in performance such as great UV stability as well as many others.
6 Advanced Thermoset Technologies - Polycarbamide Technology Key attributesVery rapid cure speedLow temperature cureExcellent UV resistanceThick films in 1 pass (up to 20 mils)Good stain & chemical resistanceHigh abrasion resistanceHigh impact resistanceHigh glossCurrent LimitationsAbility to control gloss levels for topcoat applicationsAs I mentioned before some of the key attributes of the polycarbamide technology are its fast return to service due to its very rapid cure speeds. It also can be applied at very low temperatures down to 0C and results in coatings with very high gloss and ultimate UV resistance. Another key attribute is that a thick film – up to 20 mils - can be applied in one coat. Again as with all technologies there are some limitations and for the polycarbamides one of them being adhesion to damp concrete. This is due to the reaction of the moisture with the isocyanate. And because of it’s very rapid cure speed the recoat window is not very long.
