Loctite® SI 5640T Seals Plastic Electrical Components from Outdoor Contaminants



Rocky Hill, Conn. -- Henkel Corporation has introduced Loctite® SI 5640T, a 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, this low viscosity silicone offers strong adhesion to plastics and resists 85C/85% RH aging conditions.



Loctite® SI 5640T Silicone Potting Compound is flame retardant when applied in thicknesses as low as 6 mm. Gelling in just 5 minutes, the potting compound delivers 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 including batteries and wires.



Loctite® SI 5640T Silicone Potting Compound offers 30 shore A hardness and elongation greater than 100%. The two parts of the adhesive appear grey once mixed and cured. The silicone is available in a 490 ml dual cartridge package or in 5 gallon and 55 gallon drums for high volume production environments. The components must be combined in a 10:1 mix ration to ensure proper cure.
