Addition Silicone Rubber

GOLOHO Addition Silicone Rubber produces no by-products rtv grease in the curing process, allowing their use in deep section and complete confinement.GOLOHO Addition Silicone Rubber has two types, one is one-part silicone rubber, the other is two-part silicone rubber.One-part addition silicone rubber is heat-cured, thermally conductive adhesives. These adhesives will develop good, primerless adhesion to a variety of common substrates including metals, ceramics, epoxy laminate boards, reactive materials and filled plastics. For most users, GOLOHO Addition Silicone Rubber should be operational over a temperature range of -45-200℃ for long periods of time. However, at both the low and high-temperature ends of the spectrum, the behavior of the materials and performance in particular applications can become more complex. So additional tests should be executed before use.

Long-term, reliable protection of sensitive circuits and components is important in many of today's delicate and demanding electronic applications. Addition-cure silicone should be cured at 100℃ or above the cure rate is rapidly accelerated with heat. Addition-curing materials contain all the ingredients needed for cure with no by-products from the cure mechanism. Deep-section or confined cures are possible. Cure progress evenly throughout the material. One-part addition-cure silicone rubber should be kept tightly closed at low temperature (below 5℃).Two-part addition silicone rubber are room temperature or heat accelerated cure. When the two components are thoroughly mixed in a 1 to 1 mix ratio, cure reaction begins. Initially, cure is evidenced by a gradual increase in viscosity, followed by gelation and conversion to a solid, flexible elastomer, which is well suited for the protection of electrical/electronic applications. They cure without exotherm at a constant rate regardless of sectional thickness or degree of confinement. Thus, deep section and complete confinement are preferred. At the same time, no by-products are produced in the cure process. Two-part addition-cure silicone rubber should be kept tightly against oxygen and moisture at room temperature.
