Perdure AU52

Chemical Family: Polyurethanes (PU)

Perdure AU52 is a two-part, clear acrylic polyurethane coating with excellent gloss retention. Perdure AU52 is used as a sealer/coating over a variety of substrates. Perdure AU52 cures to a very tough, abrasion-resistant film with exceptional exterior durability, chalk resistance, color stability, and long-term gloss retention. Perdure AU52 has been designed for use over concrete, acid-stained surfaces, exposed aggregate, brick pavers and various types of decorative concrete.

Composition: Perdure AU52 is a two-component, Acrylic Aliphatic Isocyanate Polyurethane.
Installation: Apply Perdure AU52 over properly prepared surfaces.; Surfaces must be free from oils, grease, water or other foreign matter.; The surface should be dry and above 50°F and rising.; Relative humidity should not exceed 85%.; Perdure AU52 is moisture sensitive during application and initial cure.; Do not apply if the surface temperature is within 5°F of Dew Point.; Not recommended on floors susceptible to hydrostatic pressure.; The best methods of application are using lambswool applicators or mohair rollers.; Perdure AU52 can be brushed by using pure Chinese soft bristle brushes.; For rolling, use a shed-resistant phenolic core mohair cover.; Roll in the same direction, always keeping a wet edge.; Do not over roll product.; For safety and proper curing, proper ventilation is necessary throughout application and cure.; When using pigmented intermediate coats, be sure the batch numbers are all the same to provide a uniform base color.; Perdure AU52 can be sprayed with an airless or conventional unit.
Technology: Ready-to-Use Products
Considerations: Do not use solvent-based acrylic as a primer.; Use over properly prepared concrete surfaces.; Applications heavier than 200ft²/gal may result in solvent entrapment and possible blistering.; Effective moisture vapor barrier needed directly under concrete slab.
Labeling Claims: Low VOC
Application Methods: Brush
Surface Preparation: Surface Preparation is the most critical portion of any successful resinous flooring system application.; All substrates must be properly prepared as outlined in Düraamen's Technical Bulletin # 1.; Work must be performed by trained or experienced contractors or maintenance personnel.
Substrate Requirements: Substrate temperature must be a minimum of 55°F before, during and 72 hours after installation.; It must have an effective vapor barrier directly under the substrate.; It must be used only on properly prepared surfaces.; The surface must be free of dirt, waxes, curing agents and other foreign materials.; It does not function as a crack reflective membrane.
