Adhesives for Optics - Adhesives, Sealants, Coatings and Potting and Encapsulation Compounds for Optical Applications

Master Bond offers the products and expertise you need. We solve problems and specialize in optical applications. Our line of products includes one and two component epoxies, silicones, polyurethanes and one component UV curable compounds. For rapid, room temperature curing applications we offer single part cyanoacrylates. Some outstanding features of our optical systems are excellent light transmission characteristics and superior non-yellowing properties; along with an array of systems where the index of refraction ranges from a relatively low 1.43 up to 1.61. All Master Bond products have been carefully processed to exclude such potentially objectionable contaminants as chlorine and other halogens as well as sodium and related elements.

Our formulations are available for use in small to large quantities and are freshly prepared to ensure maximum shelf life. Particularly noteworthy are grades that offer exceptional water resistance, NASA low outgassing approval, high thermal stability and low stress properties. Additionally, special compounds have low temperature/cryogenic serviceability, superior thermal conductivity and are able to withstand exposure to vibration, impact and shock.

Master Bond works closely with both material suppliers and research institutions to utilize the most advanced of polymeric materials. We offer innovative solutions and have developed many unique compounds which work to enhance performance properties and processing requirements. Of particular interest is Master Bond EP30-3, a two component epoxy with superior chemical resistance, optical clarity and serviceability up to 400°F. Another highly unusual compound is Master Bond EP37-3FLF. It has a very high flexibility, low viscosity, optical clarity and cures at room temperatures. One component UV14-3 provides fast cures at ambient temperatures upon UV light exposure and is easily removable by conventional solvents. It also possesses a very low index of refraction of 1.450. Master Bond UV18S has superb resistance to acids, bases and solvents and substantially less shrinkage upon cure than conventional UV cure systems. Water vapor permeability is also excellent.
