Gerflor GERSEAL 11 BROWN (290ML-CT)

Gerseal 11 MS Polymer Elastic Joint Sealant

Overview

Gerseal 11 is a high-quality, one-component MS Polymer joint sealant designed for low movement joints requiring excellent adhesion and long-term elasticity. Chemically neutral and moisture curing, it provides high bond strength on a wide variety of substrates while remaining free from isocyanates, solvents, halogens and acids. Its easy application, UV resistance and excellent adhesion to Batiflex floor coverings make it suitable for aerospace, transport and industrial sealing applications.
