National Coatings has the unique ability to address the difficulties and failures that aged single-ply roofing experiences. Most roof coatings require caustic primers, acid etching agents, or high VOC solvents that need to be rinsed off and sometimes collected for disposal, adding additional cost to a roof life extension project. NCC's products have the unique ability to coat to single-ply roofing membranes without the need to use any of these harmful products. Our state of the art single-ply coating systems adhere directly to single-ply substrates providing a monolithic membrane without any of the seams that can be prone to failure. Coating restorations do no count as a new roof under most building codes, eliminating the need for periodic and costly tear-off's. This process allows for a truly sustainable roofing system by performing coating maintenance every 10 years.

AcryPly_Acrylic_Diagram_-_A502_eliminatedWhat's our secret? The AcryShield® A502 base coat! This single-ply base coat is the industry leader, ultra low VOC, high performance base coat for hard to coat surfaces such as Hypalon®, TPO, EPDM, and PVC roofing. A502 base coat eliminates the need for costly roof replacement and provides unique AcryLock technology to tenaciously adhere directly to EPDM, TPO and Hypalon without the need for additional primers or an etching rinse. A502 also provides an additional layer of waterproofing, superior adhesion, and resistance to ponded water.

National Coatings knows how important it is to be environmentally-friendly and conscious of our carbon footprint. We constantly evaluate our products and ingredients to improve their capabilities of sustainability, energy efficiency and reduction of toxins emitted into the atmosphere. After many experiments and laboratory testing's, we are proud to offer both a roof restoration system - AcryPly System, and a roof maintenance system - ARM System, where each offers excellent sustainability and renewability, increased energy efficiency and conservation and ULTRA low VOC's (Volatile Organic Content).

Restoration System - AcryPly Roof Restoration for TPO

AcryPly-TPO-Diagram---VOC-Info-A502-eliminated

  • Where roof substrates are smooth, such as with an existing TPO roof membrane, an all acrylic AcryShield system may be used. 
  • Polyester fabric across the entire roof field creates an extremely durable reinforcing layer.
  • AcryShield A502 ultra-low VOC - 0.5 base coat provides unique AcryLock™ technology to tenaciously adhere directly to TPO without the need for additional primers or an etching rinse.
  • A502 base coat provides an additional layer of waterproofing, superior adhesion, and resistance to ponded water.
  • AcryShield A500 or QuickSet version A600, contain ZERO VOC's, provides industry leading UV protection, longevity and brightness. These top coats are formulated for superior dirt pick-up resistance and protection against biological attach, such as algae. 
  • A500 exceeding all ASTM D6083 requirements.
  • QuickSet A600 exceeds ASTM D6083 requirements for critical properties such as tensile strength, elongation, wet adhesion and weatherability.

AcryShield A502 Roof Coating...Often Imitated, Never Duplicated

Posted by Nicole Gale on Thu, Jun 12, 2014 @ 08:00 AM

roof coatingAcryShield A502 was introduced by National Coatings Corporation in 2006 after three years of intensive research, including both laboratory and actual in-service field testing.  The coating was designed to provide a primer/base coat to be applied to thermoplastic and thermoset single ply membranes, such as PVC, PIB, CPE, TPO and EPDM.  Previously, the only primers used for coating these membranes were solvent borne, which required warning labels, had very high VOC (volatile organic content) and required extreme care when applying to prevent fumes from entering the building.  The only other option for coating EPDM was a "prewash" or "rinseable primer" that had a very high, corrosive  pH, so high that it would react with human skin oils, causing chemical burns. 

AcryShield A502 has three inherent advantages over the previously used primers:

  • It is water borne, so there is no concern about flammable solvents, VOC or fumes entering buildings.
  • It replaces both specialty primers for the thermoplastic membranes and the corrosive rinseable primer for EPDM.  Thus there is no need for separate primer/basecoats for different types of roofing membranes.
  • Its VOC is only 0.5 grams per liter.

The next time a project calls for coating single-ply roofing membranes, the roofing contractor, consultant or specifier should demand National Coatings Corporation AcryShield A502
