When it comes to specialty jobsite applications, pros trust only the best quality products to help them tackle the job. That’s why DAP, a leader in the home improvement and construction industries, has expanded its product offerings with all-new sealants formulated specifically for the HVAC professional. HVAC Silicone and High Temp Silicone sealants deliver superior durability and performance for a long-lasting seal in the most extreme applications.

“Professionals who work on high temperature applications prefer a sealant they can count on to maintain its bond and flexibility,” said Jennifer Johnson, Group Product Director at DAP. “New DAP HVAC Silicone and High Temp Silicone sealants not only stand up to greater temperatures and bond to a wide variety of surfaces, but they’re also formulated to deliver a durable seal that won’t shrink or crack in extreme temperatures.”

DAP created the new HVAC Silicone especially for HVAC jobs such as sealing around air conditioners, dampers, ductwork, furnaces and vents. Its unique formula provides a weather resistance seal, optimum flexibility and durability, and superior adhesion to many common building materials. The sealant is also NSF certified, safe for incidental food contact, and is available in multiple colors to match the work surface, including white, clear and aluminum. With an extreme service temperature range of minus 40 degrees to 475 degrees Fahrenheit, DAP HVAC Silicone outperforms where the competition fails.

DAP High Temp Silicone is a high-performance sealant designed for the most extreme temperature applications up to 550 degrees Fahrenheit, including sealing around industrial ovens, flue piping, boilers, heating elements and flanged pipe joints. Not only is it formulated to maintain flexibility and durability, but it also delivers superior multi-material bond strength and is red in color for easy identification. What’s more, DAP High Temp Silicone is 100 percent waterproof so professionals can count on a quality seal both indoors and outdoors.

Both DAP HVAC Silicone and High Temp Silicone sealants meet ASTM C920 and are now available at a variety of local home improvement retailers. For more information, visit www.dap.com
