The demand for encapsulants and potting materials is rising dramatically with the market size projected to reach USD 3.13 billion by 2021, registering an annual growth rate of 3.7% between 2016 and 2021 Increasing demand from the consumer electronics industry is the major driver for the potting compound market (Research and Markets report May 16).
Techsil’s RTV27844 is a crystal clear, low viscosity, 2-part silicone which cures at room temperature to a high strength rubber with a thermal conductivity of 0.45 W/mK. Used potting solar cells and assemblies where component identification is desirable. PU22985 is a 2-part water clear potting polyurethane which cures to form a tough 85 Shore A material with good abrasion and hydrolysis resistance and thermal conductivity of 0.3 W/mK. MG 8322 is a 2-part clear potting epoxy which provides a tough resilient finish to environmental and chemical ingress; used to pot LEDs and electronic assemblies in protective blocks. TSE3051is a convenient 1-part silicone which cures to a soft transparent gel. With low viscosity it is able to penetrate complex assemblies and once cured provides cushioning for delicate components and protection from humidity and dirt.
