Besil 9316 9317 9320 one part RTV thermal conductive silicone adhesive

Type

None-flowable, one-part, moisture-cure RTV silicones.

Physical Form

  • cure to flexible elastomers; formed film with thermal conductive rate

Special Properties

  • Room-temperature;
  • resist humidity and other harsh environments;
  • Good dielectric properties; self-priming adhesion;
  • Low stress;
  • Thermal conductive;

Features

  • BESIL   93   series   is   a one-component,  fast skin-curing, non-corrosive silicone adhesive sealant that cures on exposure by moisture to form an elastic silicone rubber.
  • BESIL 93 series has excellent corrosion-free adhesion to metals, including copper, plastics, ceramics, glass, etc, without the use of primers.
  • Excellent high and low temperature resistance: from –60℃to 250℃.
  • Excellent weather ability, water and chemical resistance
  • Excellent electrical insulation properties.
  • Simple and easy-to-use one-component system.
  • Good thermal conductive

Application

  • Electricity
  • Solar
  • Equipment
  • House-hold
  • LED lighting
  • Power supplies
  • ECU moldue
  • Semi-conductor,
  • High-power transistor
  • Thyristor diodes

How to use

  • Clean the surface thoroughly, keep dry and loose debris. Clean with a solvent.
  • Cut the tip off cartridge and attach nozzle to cartridge. Full the joint completely.
  • Sealant skins in 5 minutes, is touched dry in 10 minutes and cures in 1-2 days depending on application.
  • Full bond strength is achieved in 7 days

How to apply

Apply a bead of Besil 93 series Adhesive/Sealant (see Handling Precautions) to one of the prepared surfaces, then quickly cover with the other substrate to be bonded.

On exposure to moisture, the freshly applied material will “skin-over” in about 2-5 minutes at room temperature and 50% relative humidity. Any tooling should be completed before this skin forms. The surface is easily tooled with a spatula. The adhesive/sealant will be tack-free in approximately 5 minutes.

Cure time

After skin cured continues inward from the surface. In 24 hours (at room temperature and 50% relative humidity) Besil 93 series Adhesive/Sealant will cure to a depthof about 2mm. Very deep sections, especially when access to atmospheric moisture is restricted, will take longer to cure completely. Cure time is extended at lower humidity levels. Before handling and packaging bonded components, users are advised to wait a sufficiently long time to ensure that the integrity of the adhesive seal is not affected. This will depend on many factors and should be determined by the user for each specific application
