NuSil Technology, a manufacturer of silicone-based materials for aerospace, aircraft, electronics and photonics industries, has announced the launch of an extension to its line of adhesives and sealants. R-3930 is a fluorosilicone, one-part silicone elastomer designed to cure under ambient conditions.

The company also recently released a new line of high-purity gels at Sensors Expo 2009 which was held in Rosemont, Ill (USA)
Tested alongside fuels, such as JP8 and DiEGME, NuSil’s R-3930 is ideal for coating, sealing and bonding applications requiring fuel or solvent resistance. It is a room temperature vulcanising (RTV) silicone elastomer dispersed in tertbutyl (T-butyl) acetate with a wide operating temperature range.
“R-3930 addresses many of the challenges faced while working on large platforms or where surfaces may be exposed to harsh conditions such as corrosive solvents or fuels,” the company said.
Intended for spraying and dip-casting, R-3930 bonds aggressively to most surfaces without the need of a primer and is excellent for consideration as a coating to minimise ice adhesion.
 
High-purity gels
LS-3354, LS2-3354 and LS3-3354 are high-purity gels that reduce moisture permeability by 80 per cent when compared to other silicone gels used for encapsulation.
Thet are designed for potting, encapsulating, backfilling and dampening applications requiring a soft gel with optical clarity. These gels have a refractive index of 1.54 and are available in a convenient 1:1 mix ratio. With viscosities ranging from 3,500 cP to 8,000 cP, the gels are excellent for dispersing phosphors to obtain a high-brightness white light. Cure can be achieved at ambient temperatures with humidity or accelerated with the addition of heat.
The gels are considered excellent for protecting fragile electronic components from environmental concerns such as dust, debris, and moisture.
