Kafuter-5203 Thermal Conductive Adhesive/LED light Silicon Rubber Gel
FEATURES
K-5203 is a reinforced thermally conductive silicone elastomer with great adhesion, insulation and dissipation.
(1) one part, room cure, packing in soft metal tube.
(2) Excellent in cold and high alternating resistance (-60°c~ 280°c).
(3) No peeling and good disassemble after long time usage.
(3)The elastomer with high bonding strength , the shear strength is 30kg/cm3
APPLICATION
fill, bond, and seal in electronics
1. the gap between CPU and raditors
2. the gap between thyristor control modules and radiator
3. the filling of high-power electronics modules and radiators,etc.
This elastomer can instead of silicone grease in filling and bonding the gap between CPU and radiators, thyristor control modules and radiator, high-power electronics modules and radiators, etc.
The elastomer filling can instead of traditional filling ways by its good use and low cost.

HOW TO USE
Preparation
Clean the un-bonded or uncoated surfaces by removing the rust, ash, and oil, etc.
Application
Pierce the opening with the tip of the cap. Fix the nozzle, and coat the clean surface evenly with the adhesives, then bond the two surfaces.
Curing Condition
a.The curing progress is from outer surface into inner surface.
b. The elastomer get cure with the depth of 2~4mm in 24 hours (at room temperature, 55% moisture). if the bonded parts is too deep (especially the parts not easy to contact with air) or the temperature is too low, the full curing time will be extend.
Advise user preparing enough time to let elastomer get full cure in order to keep the properties stably.
ATTENTION
1. After the application, screw its nozzle tightly and store in dry and cool place for next time using.
2. There may be some cured gel around the opening when you use it again, just remove the cured, and use the uncured.
PACKAGING 80g/ tube
STORAGE
Store in cool and dry place, the shelf life is 12 months (≤25°c)
