From high performance LED chip packaging encapsulants and potting materials to thermal management solutions and adhesives for bonding lighting assemblies, Techsil supply a variety of materials to provide environmental protection, extend service life and improved light performance. Product chemistries include Silicones, Polyurethanes, Epoxies, Greases and Pressure Sensitive Tapes.

Techsil work in close consultation with engineers to ensure the correct performance specification is achieved by building on our years of expertise with these concepts. Techsil’s materials are used in many LED applications such as LED light engines, linear modules, luminaires, housings, architectural lighting, security and flood lighting, outdoor LEDs, oceanic LEDs, panel mounted LEDs and PCB mountings.

LED Encapsulants, LED Potting and Protection


The need for encapsulants for LEDs is rising dramatically and the requirements are high, with engineers looking for products offering brilliant clarity, high brightness, along with excellent thermal characteristics. Techsil provide a wide range of materials for LED assembly that provide protection from harsh environmental factors such as moisture ingress, vibration, scratches and thermal shock.

Designed to have, in particular, an excellent refractive index, all materials have great UV stability. Included in this range are:
  • PU22985 (NEW) – 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 (NEW) - A clear potting epoxy which provides a tough resilient finish to environmental ingress.
  • RTV27844 - A crystal clear, low viscosity, 2-part silicone which cures at room temperature to a high strength rubber.

Examples of Thermal Management Adhesives, Sealants, Greases and Tapes for LEDs


  • TIM 202331 Tape (NEW) - a white, heat transfer tape for bonding heat sinks to LED strips and units. Thermal conductivity 2W/mK. (Other tapes available with up to 3W/mK.)
  • RTV1084G - a 1-part grey silicone with high thermal conductivity of 2.3 W/mK which cures to a tough but pliable rubber
  • TIM11021 G - a 1-part, grey, non-setting, silicone paste with thermal conductivity of 2.1 W/mK

As an authorized distributor for Momentive Performance Materials Techsil also supply Momentive’s comprehensive range of silicone material solutions that are excellent candidates to address a wide array of LED applications, including glob top encapsulants, thermal gels, lens materials, die attach silicones and dot matrix potting materials.
