LCI300 SpecSeal LCI Intumescent Firestop Sealant, 10.1 oz Tube, Red

The LCI300 Intumescent Firestop Sealant is a professional-grade, water-based fire protection sealant designed for through-penetration firestopping and construction joint applications. Featuring an intumescent formulation, excellent caulking properties, and water-resistant performance after drying, this sealant provides a practical solution for commercial and residential building fire protection systems.

Designed to help prevent the spread of fire and smoke through approved building penetrations, the LCI300 incorporates intumescent technology that expands when exposed to elevated temperatures. This expansion helps seal gaps and openings when the material is installed as part of a tested firestop system.

The water-based formulation provides convenient handling and application, making it suitable for professional contractors working on new construction, renovations, and building maintenance projects.

The sealant features excellent caulking characteristics that allow convenient application on vertical surfaces and overhead locations. Its consistency helps installers apply the material to compatible joints and penetration openings while maintaining the required sealant placement.

Once properly dried, the LCI300 provides water-resistant performance and is formulated not to re-emulsify when exposed to moisture under applicable service conditions.

The sealant is supplied in a 10.1-ounce tube, making it suitable for use with compatible dispensing equipment. Its red color provides convenient identification during installation and inspection.

The LCI300 is identified in the supplied product information as UL Classified and FM Approved. Actual fire-resistance performance depends on the applicable tested assembly, installation configuration, and manufacturer requirements.

Ideal for electricians, firestop contractors, construction professionals, and building maintenance teams, the LCI300 offers an economical solution for approved through-penetration and construction joint firestopping applications.
