McCoy Silicones Limited, an ISO 9001:2000 Certified Company manufactures High-Performance 2-Part Silicone Sealants and Adhesives, Sikasil SG-500. The High-Performance 2-Part Silicone Sealants and Adhesives are neutral, condensation-curing, elastic silicone adhesive with high mechanical strength and excellent adhesion to many construction materials such as glass and metal. The High-Performance 2-Part Silicone Sealants and Adhesives are professional silicone adhesive. These are specially designed for sealing, bonding and mending in construction applications. It is universally applicable for the structural bonding of fa?ade elements. This High-Performance 2-Part Silicone Sealants and Adhesives are perfect for bonding glass and metal in structural glazing structures. The High-Performance 2-Part Silicone Sealants and Adhesives are available in black. The two parts component A [base compound] and component B [catalyst paste] must be mixed, and cure at room temperature to form an elastomer.
The characteristics and advantages of the High-Performance 2-Part Silicone Sealants and Adhesives are:
