Two component, optically clear Master Bond MasterSil 149 is used for potting/encapsulation of voltage regulators, high voltage transformers and other electro-optic assemblies. Curable at room temperature MasterSil 149 has a low mixed viscosity of 4,000 cps. It protects assemblies from dust, moisture, ozone, thermal shock and mechanical vibration. MasterSil 149 is serviceable from -40°C to 200°C.
MasterSil 149 is a condensation curing silicone system. An “escape” path is required to allow for the release of non-hazardous byproducts formed during the mixing process which promotes completion of the curing cycle. MasterSil 149 has a mix ratio of 100 to 8.5 by weight. Cure speed can be accelerated by using heat.
Master Bond MasterSil 149 has a Shore D hardness of 20 and an elongation of >300%. Its volume resistivity is 2.5 x 1015 ohm/cm. Optically clear, MasterSil 149 has a refractive index of 1.403 and a linear shrinkage of <0.4%.
Master Bond two component silicone compounds are used in the electronic, optical, medical, electrical, oil/chemical processing industries. They are noted for their superior flexibility, thermal stability, and resistance to corrosion, vibration and thermal cycling. Grades include thermal conductive, electrical conductive and electrical insulative systems. Additionally, a USP Class VI biocompatible product is available for medical device assembly.
