Adjusting Adhesive Flash-Off Times

Changes in season, weather, sunlight, humidity, and temperature can dramatically affect flash-off times of single-ply membrane adhesives. And overall performance of adhered single-ply roof systems rely on proper membrane adhesion. ReadyFlash Technology allow contractors to manipulate adhesive flash-off times by choosing between two different-colored facers on every board.

SecurShield products with ReadyFlash Technology feature a dark-colored coated glass facer (CGF) on one side of the insulation board and a light-colored CGF on the other. Utilizing the sun’s energy, the dark facer accelerates adhesive flash-off; while the light facer slows it down. Contractors can choose between dark and light facers on the same insulation board.

ReadyFlash can help address the challenging rooftop scenarios described below:

• On a hot, sunny day the adhesive is flashing off prior to the crew completing application. Consider installing the light facer up to slow down adhesive flash-off time.
• On a cold day, the adhesive flash-off is taking longer than desired. Consider installing the dark facer up to speed up adhesive flash-off time and improve productivity.
• The applied EPDM membrane bonding adhesive is flashing off quicker than the adhesive applied to the insulation. Consider installing the dark side up so the adhesive on both surfaces can flash-off at the same time when applying bonding adhesive to both the membrane and insulation simultaneously.
