List of featured suppliers of SEALANTS Mastic: by Composition: Elastomeric on Building Products Index
Sealants and mastics that have an elastomeric composition are commonly used for filling gaps and cracks in building materials. These materials have the ability to stretch and move with the substrate without cracking or breaking, making them ideal for areas that experience some level of expansion or contraction. Elastomeric sealants and mastics are often made with a combination of polymers and resins, which allow them to maintain their flexibility over time and resist weathering and UV degradation.
