A Look Into Pecora Contractor Silicone

Pecora offers a complete line of flexible, protective, silicone sealants, built on a relentless pursuit of perfection for the better part of 40 years. Our wide variety of silicone offerings address most project requirements, whether it’s a specific adhesion requirement, modulus, joint type, rheology, or cure speed, Pecora offers a solution.

Our expert team understands the many factors involved in choosing a silicone sealant—including thermal expansion and contraction, wind load, hygrothermal movement, and more—and can help you select the right sealant for extending the life and integrity of your building structure. Pecora’s innovative sealant solutions minimize costs from wasted product, stained substrates, or aged, failing sealant.
