B&L Pro MS Firerate

Product Description

B&L PRO MS FIRERATE LIMESTONE is a high quality single component fire rated joint sealant with high adhesive strength. When cured it will provide a tough, flexible seal capable of achieving ±25% joint movement. This sealant provides excellent elastic recovery and excellent weather resistance assuring a long term fire rated joint seal.

It is based on MS-Polymer®, chemically neutral and fully elastic. For use in high movement joints in construction, automotive, marine and aerospace areas where a tough flexible rubber is required with good fire retardant characteristics.
