Premium Performance for Through-Penetrations & Joints

PEN300 is a one-part, neutral curing silicone firestopping sealant designed for use in applications where properties such as excellent water-sealing, elasticity, or extended operating temperatures are required.

PEN300 Silicone Sealant is highly elastomeric and adheres tenaciously to virtually all common construction surfaces. Its ± 50% movement capabilities allow for the design of construction joints with excellent movement capabilities. It’s resilience is also well suited to the sealing of pipes exhibiting expansion, movement, or water-hammering. In addition, PEN300 is an excellent choice for environments with higher than normal continuous operating temperatures.

PEN300 is UL tested and classified with an extensive array of systems and designs for both through-penetrations and joints. PEN300 cures in the presence of moisture, skinning rapidly to provide excellent early resistance to wash out as well as excellent L ratings.

For ease of application, PEN300 is available in both non-sag (gun grade) and self-leveling viscosities.
