High performance elastomeric intumescent expansion joint sealant.
Single part fire rated MS Polymer based sealant designed for sealing expansion joints and compression joints where frequent movement is anticipated as part of a fire resistant assembly. The sealant is formulated to intumesce on exposure to high temperatures to form a fire and smoke resistant joint seal.
It is non-hazardous, will not emit halogenated by products under fire conditions and contains no raw materials known to have an oestrogenic effect in the environment. The sealant offers excellent levels of adhesion to most construction substrates and can be overpainted with oil, polyurethane or latex paints.
