DESCRIPTION
The room temperature curing, XE2355 is a condensation curing silicone which cures with air moisture and it is best suited for coating, potting, sealing and encapsulation of electroniccomponents. XE2355 has superior flowability and will bond to many clean surfaces without the aid of primers.These surfaces includes plastics, metals, glass, ceramic and silicone rubbers. After curing, like general silicone rubbers, posses excellent heat, cold, weather resistance. As well as excellent electrical properties for use as sealant for electrical communications machinery, automotive parts and as potting material for small parts and LEDs.

KEY FEATURES
Primerless adhesion to many substrates
Absolutely no corrosion
Superior flowability : Pourable, self-leveling product for potting, encapsulating and coating for
circuit assemblies and LED parts
Excellent heat and cold resistance : Retains elastomeric properties for long periods at temperature up to 200°Cand down to - 30°C
Excellent electrical properties : Even in harsh environments,XE2355 is retains its electrical properties
Excellent durability : High quality weatherability and even if used outdoors, dose not deteriorates
Low viscosity : Flow characteristics allow rapid dispensing with automated equipment

APPLICATIONS
Electrical insulation, thin section poting, protective coating
Water proof sealant as well as potting for electrical and communication machinery and for more good to LED parts
Air tight sealant for materials to keep out water and dust
Other parts requiring heat and coldproof properties and sealant of machinery and LED used outdoors
