HENKEL CORP.: Silicone Potting Compound

May 24, 2013

Loctite®SI 5640™ is a new two-part, self-leveling silicone potting compound designed for electrical and electronic potting applications that require UL 94 VO compliance. Designed to ensure the integrity of electrical components by sealing against corrosion and outdoor contaminants, the low-viscosity silicone reportedly offers strong adhesion to plastics and resists 85C/85% RH aging conditions.

The potting compound is reportedly flame retardant when applied in thicknesses as low as 6 mm. Gelling in 5 minutes, the potting compound can deliver high throughput in automated processes that require fast cure times. This material is designed for use on outdoor electrical devices such as electrical meters, signage/displays, speakers, HVAC components, appliances, solar panels/wiring, wind turbines and LED lighting. The adhesive can also be used on marine vessels and VRM components, and can pot and seal internal electrical components such as batteries and wires.
