AcryShield 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 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.

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. 

 

National Coatings' reflective roof coatings can reflect up to 92% of the sun's heat/harmful UV rays. This drastically reduces energy consumption and use of HVAC systems to lower the temperatures inside the building. Reflective roof coatings are excellent at reducing roof temperatures and prohibiting a majority of heat absorption into the building. They work by reflecting the sun’s heat back into the atmosphere, preventing the roof and building from absorbing the heat, resulting in greater energy efficiency, cooler interior building temperatures, less temperature fluctuations throughout the day, greater cost savings on energy utility bills and increase comfort for your tenants and customers occupying the building.

The reflective roof coatings work similarly to wearing a black shirt versus a white shirt on a hot day. The white shirt keeps you cooler, more comfortable and the black shirt attracts the heat and in turns makes you hotter. A cool roof using reflective roof coatings is a monolithic, watertight, spray applied system that is installed directly on top of your existing roof membrane (asphalt, single-ply, SPF, concrete, or metal) to protect and extend your original roofs’ lifespan. Reflective roof coatings are excellent for reducing energy consumption by keeping the building cool, but they also provide durable protection from the harmful UV rays. The sun’s UV rays are the leading cause of roof failure as they dry out and cause your roof to crack, become brittle, tear and eventually leak. Reflective roof coatings do not absorb the majority of the UV rays; therefore, protecting your roof membrane by prohibiting premature roof failure and damage to be done to your roof.

According to ENERGY STAR®, “Americans spend about $40 billion annually to air condition buildings – sixth[sic] of all electricity generated in this country.” Installing a Cool Roof with reflective roof coatings can drastically reduce this amount of energy consumption cost.  National Coatings cool roof coatings significantly lowers roof surface temperatures, extending roof life, directly impacting the temperature of the interior building, allowing it to remain cooler - reducing the use of HVAC equipment to cool your building.

TPO roofing has been known to be one of the hardest, most stubborn substrates to adhere to. Most roof coating manufacturers require an initial primer or etching rinse to be done before applying a base coat to the TPO membrane. Unfortunately, this adds additional labor time and costs to the roof coating project. National Coatings has made it a point to focus a majority of their efforts on providing durable, waterproofing solution to the roofing community that surpass their competition. With this goal in mind, National Coatings created the AcryShield A502 base coat, which DIRECTLY adheres to aged or failing TPO roofs without an additional primer or etching rinse.

The AcryShield A502 offers the best solution in the roofing industry for restoring a TPO roof because of its ability to tenaciously and directly adhesion to the TPO membrane. The A502 base coat eliminates the need for a costly roof replacement, lowers project costs and increases job efficiencies. There is no need to capture caustic contaminated water from the primers and etching rinses, which a majority of municipalities require. This provides safer work conditions and is better for the environment.
