Transparent Potting Resins and Gels
Soft Elastic Transparent Gels
Application of silicone gel is particularly easy with a standard 2K application equipment,
dispensing or monofi lament system. The removal of silicone gel for repair or re-work is also
very simple. It is ideally suited to high volume production lines with very short process time.
Viscosities in the range 200 mPas to 10.000 mPas are available to suit more requirements.
BECTRON® SG 75xx series are available as a “fl exible and non-sticky” gel, as well as a “softelastic”
or “soft elastic sticky” gel and as well as a “soft and sticky” or “soft and non-sticky”
gel over the temperature range -50 °C to 206 °C. The electrical insulation properties are
excellent with good adhesion to many substrates.
BECTRON® SG 75xx series has very good electrical properties particularly suitable for a wide
range of electronic elements. It provides protection against moisture, corrosion, vibration and
migration. Many uses are possible, from securing of individual components like cable joint
boxes to the protection of IGBT´s.
Transparent Resins UV Stable form Soft to Hard
BECTRON® PU 453x series in combination with hardener BECTRON® PH 4901 are 2 component
systems which cure to form a resilient but fl exible transparent polyurethane. All are solvent free
systems with no bleeding characteristic even at high temperature exposure.
BECTRON® PU 453x series are designed for situations where visibility of the potted material
is required, such as optoelectronics and sensor technology. All systems are non-yellowing in
daylight. They can also be used as a clear resin for automotive displays or LED modules where
high UV stability is needed..
