RTV Potting Silicone Rubber For LED

 

Product Description:

The silicone rubber (acrylic silicone/acrylic sealant/silicone/sealant/adhesive/potting sealant/potting adhesive/potting compound/UV glue/flange sealant/conductive sealant/Huitian adhesive/Huitian potting compound/huitian sealant/electrical sealant/electronic adhesive/epoxy sealant/epoxy adhesive/PU adhesive) two components, medium hardness.

Transparent.

Condensed type, good bonding capacity on base material.

 

Product Features:

  1. Curing in room temperature, suit for potting by manual.
  2. Good transparent, anti-yellowing.
  3. Release ethanol molecules during curing, no corrosion for components.
  4. Very low viscosity and good flowing, good performance on operation.
  5. Excellent thermal resistance, damp resistance, cold resistance, extend the electronic components lift after application.
  6. Under the condition of no base coat, good bonding performance for components and parts, guide line.

 

Typical applications:

LED outdoor screen, Logo screen, Nixie tube, PCB base panel, Pixel tube etc LED electronic products.

Direction for using:

Mixing: Mixing rate A:B=10:1, if need to change the rate, it should be tested before applying.

Defoamation: Potting thickness less than 4mm, vacuum defoamation no needed, for the potting thickness more than 4mm, surface and inner will come into being small bubble, can vacuumize to remove.

Curing: Not suit for heating during curing, otherwise will cause cracking or small bubble on the surface and inner.

Note: After applying, B component should be sealed to isolate the air, if expose in the air long time, will cause mixing adhesive (acrylic silicone/acrylic sealant/silicone/sealant/adhesive/potting sealant/potting adhesive/potting compound/UV glue/flange sealant/conductive sealant/Huitian adhesive/Huitian potting compound/huitian sealant/electrical sealant/electronic adhesive/epoxy sealant/epoxy adhesive/PU adhesivecan not be cured.

 

Notice:

1, Keep away from children.

2, Release small ethanol molecules during curing, small irritate on skin and eyes, suggest to operate in the good ventilation space, wear gloves and goggles.

3, If touching skin, remove and wash by water, if touching eyes, wash by water and make a further handling to hospital.

4, Safety information refer MSDS.

 

Packing:

421206, 19.8KG/set A component 18kg/drum, B component 1.8kg/bottle.

 

Storage:
