Polyaspartic Coatings
Robust wall, roof and floor coatings
Robust wall, roof and floor coatings
These are robust wall, roof and floor coatings.
With regards to long term durability, Polyaspartics are the next generation of topcoats and should easily exceed ten years colour and gloss retention. The choice of primer, should one be needed, will depend on the substrate. We can of course advise you subject to a site visit.
Polyaspartic coatings are based on the reaction of an aliphatic Polyisocyanate and a Polyaspartic Ester, which is of course an aliphatic diamine.
Developments in Polyaspartic coating technology have concentrated on achieving coatings with low or near zero volatile organic compounds (VOC’s), so called compliant coatings. The unique and adjustable reactivity of the Polyaspartic esters allows for the design of fast curing coatings, which can also provide high build, low temperature curing. The pot life of the mixed two component coating can typically be adjusted from a few minutes to a few hours. Improved abrasion and corrosion resistance is also achieved.
Polyaspartic as a name is used to differentiate the coating from Polyureas and Polyurethanes. By definition, a Polyaspartic is an aliphatic Polyurea. However, Polyaspartic coatings are very different in both application and coating performance properties from conventional Polyureas.
Many Polyaspartic coatings can be applied with conventional airless spray equipment, making application much less complicated and less prone to error. Note though that correct and accurate mixing of the two part components is important.
Other differences between Polyaspartic and aliphatic Polyurethane coatings include the ability to be formulated to a very high solids content (70% to 100%) and to be applied at higher film builds (300 to 400 microns in a single coat). The faster drying of the Polyaspartics compared with typical aliphatic Polyurethanes enables a quicker painting operation.
Blocksil has proven experience in being able to have this coating type spray applied onto a 15 metre (49 feet) high GRP clad building.
