Pensil™ 300 is a one-part, neutral curing silicone sealant designed for fire-rated joint sealing.
It prevents the spread of fire, smoke, toxic gases, and water during fire conditions, while offering
primerless adhesion to most building materials such as glass, aluminum, steel, masonry, treated wood, and concrete.
With high movement accommodation, it maintains adhesion under normal environmental expansion and contraction.
