Offering a unique blend of high performance properties, Master Bond MasterSil 153 is often used in a variety of bonding and sealing applications involving optical, electrical, aerospace and medical devices. As an addition cured system, it does not require air for complete cross-linking. It can be cured over wide surface areas as well.
This two component silicone features easy handling with a one to one mix ratio by weight and its paste consistency allows for precise application. MasterSil 153 has a low exotherm and long working life of 5 to 7 hours at room temperature. It is a self priming system, which enhances its bonding abilities to a wide variety of similar and dissimilar substrates, including most metals, plastics, glass, ceramic and cured silicone rubber. This translucent silicone is also serviceable over the wide temperature range of -65°F to over 400°F.
MasterSil 153 offers exceptional flexibility that enables it to withstand severe thermal cycling as well as vibration and mechanical shock. Its softer durometer of 20-35 Shore A hardness improves its repair-ability. This formulation has other noteworthy properties such as excellent electrical insulation capabilities, superior water resistance and very low shrinkage upon cure.
If stored in its original containers, MasterSil 153 has a shelf life of 6 months. It is available in a variety of packaging sizes including ½ pint, pint, quart, gallon and five gallon container kits.
