Product features:
OPT555W
is a kind of low-Viscosity,
one-component
silicone potting adhesive, which can be cured in room temperature. It has features of

thermal cycle resistance, high and low temperature residence, being elastic and stable at -60~200°C, UV residence, aging resistance, moisture proof, electrical insulation, anti-seismic, corona-resistance, leakage-resistance. It belongs to liquid deketoxime,

single-component room-temperature-cured
silicone rubber, which is not applicable in copper and PC material adhesive which follows the ROHS order of European Union.
Typical use
1. Moisture-proof and water proof package for electronic element and fittings.
2. Protection layers of insulation material and circuit board.
3. water-proof sealing of Electricity , Telecommunication equipment and range finder for parking.
4. Water—proof package for LED Display lighting module and Pixel.
5. Potting protection for mini electronic element,

module
,
optoelectronics display device and circuit board.
Using method
1. Clean surface: clean and dry and degrease the surface before coating.2. Coating: open the cover then press the adhesive to the clean surface.3. Curing: put the equipment in the open air until it is cured from outside to inside. The adhesive will cure for 2~4mm within 24h in room temperature. It is suggested that it should be spontaneous curing in outdoor for enough long time to ensure the effect. Low temperature requires more time. Sealing adhesive with thickness of 6mm needs more than 7 day to be completely cured.
Note: OPT
