Silicone Systems

Master Bond offers MasterSil® one and two component silicone adhesives. These silicones are elastomeric systems that feature a unique combination of flexibility and high temperature resistance. One part systems require no mixing and cure by moisture in the air. Two part systems are cured by a polymerization reaction that occurs when a curing agent is added. They are frequently employed over wide bonding areas and where humidity is insufficient for complete cure of single part systems. Generally, two part systems can cure in thicker sections than one part systems.

These versatile systems expand design options. They relieve thermally induced stress between substrates with different coefficients of expansion/contraction and have high elongation properties and maintain their elasticity at low temperatures. Their weatherability over time including UV radiation exposure is excellent. Select grades have superior solvent resistance, are easily repairable after cure, have successfully withstood 1,000 hours at 85°C/85% RH, perform exceptionally in medium/high voltage applications and are optically clear.

One Part Silicone Adhesives, Sealants and Coatings

One Part Silicone Systems

Master Bond offers a large variety of one part, no mix, tin catalyzed RTV silicones. These condensation cured products provide a unique combination of high flexibility and high temperature resistance. They maintain their elastic properties over a wide temperature range, and have excellent movement capability. They are available in different hardness and viscosities, and offer resistance to vibration, shock, heat and corrosion. Certain grades offer optical transparency as well.

Two Part Silicone Compounds for Industrial Applications

Two Part Silicone Systems

Master Bond offers MasterSil® two part silicone systems for use in the assembly of medical, electrical, electronic, optical and other devices. These products provide excellent resistance to vibration, shock, heat and corrosion. Long pot life products have low exotherm and can be cured in deep cross section thicknesses beyond 1 inch for potting/encapsulation, casting usage. These low shrinkage formulations possess a long service life, can cure in a closed environment, cure more rapidly with heat and retain their elasticity over a wide temperature range.

Fluorosilicone Elastomers for Industrial Applications

Fluorosilicone Systems

Master Bond one and two component fluorosilicone adhesives, sealants, gasketing, potting compounds protect against erosion/corrosion and withstand exposure to oils, fuels, solvents and other aggressive fluids. These products have good mechanical strength properties and bond well to many similar and dissimilar substrates. These include glass, silicone rubbers, stainless steel, titanium, aluminum and many plastics. Fluorosilicone elastomers feature enhanced performance capabilities. They also resist outdoor weathering, rigorous thermal cycling, have high elongation upon cure and exceptional high/low temperature serviceability.

Applications of MasterSil® Silicones

MasterSil® one and two part silicone systems are used as adhesives, sealants, coatings and potting compounds. They are employed in the electronic, automotive, optical, medical, appliance and power industries. Our cutting edge products meet specific requirements for many diverse application needs.
