 Pecora XL-Perm

XL-PermUltra VP is a high-performance, fluid-applied silyl terminated polyurethane (STPU) that combines the best characteristics of silicone and urethane properties. Together, these properties allow the STPU to function as an air/water barrier. It can be applied in a single coat without the use of a primer, and contributes to a seamless, airtight building envelope through its excellent elasticity and crack-bridging capabilities.

XL-PermUltra VP has several advantages over similar products:

  • It offers 2-3 times as much coverage as other fluid-applied products.

  • It is compatible with a variety of wall components, thanks to its STPU chemistry.

  • It can be applied in cold and inclement weather with no wash-out and a quick set time, it eliminates delays on the job site.

  • It is UV and water-resistant.

  • It is low VOC, compliant in all parts of the United States.

  • It meets the performance requirements of NFPA 285.
