Sealant compatibility classifies sealant as chemically suitable or unsuitable to come in contact with other types of construction materials. These products may include weather resistive barriers (WRB), self-adhered membranes (SAM's), liquid applied membranes (LAMs) and building cladding. We strongly recommended pre-construction adhesion testing of all substrate coming in contact with the specified sealant. Product Category: Sealants & Adhesives
