Techsil® RTV27844

Techsil RTV27844 is a clear liquid which will cure at room temperature to a high strength silicone rubber with the addition of curing agents. RTV27844 is supplied with a curing agent in matched kits which are designed for use at a convenient 10:1 ratio by weight. RTV27844 is a low viscosity, easily pourable liquid. RTV27844 silicone rubber compound has the capability of remaining flexible at low temperatures and have been used for protection of electronic components and assemblies against shock, vibration, moisture, ozone, dust, chemicals, and other environmental hazards by potting or encapsulation of the components and assemblies. The optical clarity of this silicone rubber suggests evaluation for applications such as potting solar cells for maximum light transmission and electronic assemblies where component identification is necessary or desirable.

Key Features and Benefits:

• Convenient 10:1 mixing ratio for use in automatic dispensing or hand operations

• Low viscosity allows easy flow in and around complex parts, providing excellent electrical insulation and shock resistance

• Cure rate can be accelerated by heat

• Will cure in deep sections or enclosed assemblies without exotherm and with low shrinkage

• Chemical composition contains no solvents for ease of use on production lines

• Reversion resistance and hydrolytic stability permit use in high humidity environments at elevated temperatures

• Clarity permits visual inspection for easy identification and repair of encapsulated parts

• Retention of elastomeric properties at temperatures up to 204°C (400°F)
