Solar Junction Box Potting Silicone QJ-2066 Brochure:




This product is there and the two-component silicone sealant is a synthesis of a new thermal insulation materials, curing and hold heat, no corrosion, shrinkage, for a variety of electronic components, heat sealing, casting, the formation of thermal insulation series. Product has the following characteristics:
1: room temperature curing, curing speed, at 25 ℃ 1 hour after filling plastic to enter the next process, high efficiency, ease of use
2: waterproof, at (-60 ℃ -250 ℃) to maintain the low temperature range of silicone rubber excellent flexibility, excellent electrical properties, good thermal conductivity, chemical resistance, yellowing resistance, aging resistance.
3: with most plastics, rubber, reinforced nylon PA and PPO polyphenylene oxide materials such as good adhesion.
4: flame-retardant properties to UL94V1 level.
5: full compliance with the EU ROHS environmental protection directives.
Use
Used for waterproofing, insulation, flame retardant, thermal requirements with special potting electrical and electronic components, solar modules dedicated to the junction box potting.
