Below is a list of Silicone Adhesive manufacturers from Northridge, California. Silicone adhesive is a powerful and flexible bonding material that has an extremely high temperature resistance. It creates a permanent seal on most surfaces, including wood, glass, paper, plastic, metals, ceramic and concrete. Besides bonding two surfaces together, silicone is also used as an effective, watertight sealant to fill holes, level surfaces and seal off gaps.
