Years Established


dedicated to quality

When it comes to making permanent joints between materials such as metals, plastics, alloys, logs, electrical contacts, wood, glass, etc., Sealer’s adhesive technology really stands out among the industry…
Our research and technical staff have a proven reputation as active, responsive, and successful developers of the products you need. Our Research and Development facilities support a full range of product development needs, including but not limited to polymer characterization, formulation and compounding, performance properties testing and environmental testing.
New industrial applications call for new materials and new technology in applying these materials; still light in weight, but capable of withstanding extreme static and dynamic stresses that continue to evolve as industries evolve. Sealers is committed to the ongoing search for new, more economical, ecologically friendlier and more durable solutions.
