Silicone Systems

MasterSil® is Master Bond Inc.’s line of silicone systems. These elastomeric systems combine flexibility with resistance to high temperatures. We offer both one and two part systems that may be used as adhesives, sealants, coatings and potting compounds. MasterSil® silicones are used in the electronic, automotive, optical, medical, appliance and power industries.

Features and performance properties of MasterSil® silicone systems

Our easy to use one part silicone systems do not need mixing. They cure by moisture in the air. They exhibit strong adhesion to glass, plastics, metals, rubbers and other substrates. We formulate specific grades that are used in electrical and optical applications for both assembly and repair. As with all of our formulations, additional performance properties may include electrical insulation, thermal conductivity, electrical conductivity, optical clarity and resistance to vibration, shock, heat and corrosion. 

For Master Bond two part systems, a curing agent is added that results in polymerization reaction to facilitate curing. Two part systems may also be formulated with an array of performance properties similar to one part silicones. Both one and two component silicones blend flexibility and toughness with high temperature resistance.

Certain grades of MasterSil® silicones comply with industry certifications including USP Class VI and ISO 10993-5 for biocompatibility, UL94V-0 and UL94V-1 for flame retardance, and MIL-A-46146 and MIL-A-46146A Type 1.

Master Bond silicone products

Here are just four MasterSil® silicones that have been used in various applications.

  • MasterSil 711, is a very fast setting, high performance, non-corrosive silicone rubber that has been successfully used in manufacturing and repair applications.
  • MasterSil 151Med is a medical grade, USP Class VI approved silicone. It is an addition cure system. That features optical clarity and low outgassing. It is also excellent for potting and encapsulation applications.
  • MasterSil 153 is a two component silicone paste for bonding and sealing applications. It provides  outstanding electrical insulation and can cure in wide sections vertically and horizontally.
  • MasterSil 151AO is an electrically isolating, thermally conductive silicone adhesive with a thermal conductivity of 1.5 Watts/meter Kelvin.  This low viscosity system bonds well to a wide variety of substrates.
