Adhesive specialist Techsil has launched a range of four new optically clear encapsulants designed to have, in particular, an excellent refractive index and great UV stability; suitable for potting LED lighting assemblies.
RTV27844 – a crystal-clear, low-viscosity, two-part silicone that cures at room temperature to a high-strength rubber with a thermal conductivity of 0.45W/mK. Used for potting solar cells and assemblies where component identification is desirable.
PU22985 – a two-part water clear potting polyurethane that cures to form a tough 85 Shore A material with good abrasion and hydrolysis resistance and thermal conductivity of 0.3W/mK. Developed for potting of luminaires, LEDs and doming applications.
MG 8322 – a two-part clear potting epoxy that provides a tough resilient finish to environmental and chemical ingress; used to pot LEDs and electronic assemblies in protective blocks.
TSE3051 – a convenient one-part silicone that 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.
