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

Master Bond has the products and expertise you need. Master Bond solves problems and specializes in optical applications. Master Bond's 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 of the outstanding features of our optical systems are excellent light transmission characteristics, superior non-yellowing properties along with a range 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.

Formulation of High-Performance Optical Adhesive Products

Master Bond's 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.

Enhancing Optical Properties Utilizing Advanced Polymeric Materials

Master Bond works closely with both material suppliers and research institutes to utilize the most advanced polymeric materials. Master Bond offers innovative solutions and has developed many unique compounds 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 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.
