Product Description
Besil 8230 thermal conductive silicone encapsulant
BESIL 8230 is a two-part addition cure RTV. Comparing to condensation cure system.
Keywords:potting for module
FEATURES
• long potting life, But rapidly cured under heat.
• Contain all the ingredients needed for cure with no by-products from the cure mechanism. Deep-section or confined cures are possible.
• Require no post-cure
• Two-part, 1:1 mixing ratio
• Medium viscosity Room temperature cure or rapid heat cure
• Addition cure system: no cure by-products
• Flame retardant: meets Underwriters Laboratories UL 94-V0
• Stable and flexible from -50°C(58°F) to +250°C (432°F)
• Flexible rubber - protects against mechanical shock and thermal cycling stress at components
• Excellent dielectric properties
APPLICATIONS
• Designed to protect against moisture, environmental attack, mechanical and thermal shock as well as vibration especially where good adhesion is required.
• Typical applications include: encapsulation of amplifiers, automotive electronic units, ballast, bleed resistors, connectors, flyback transformers, high voltage resistor packs, lifting magnets, power controllers, power supplies, radio frequency induction transformers and sensing devices.

Compatibility
In some cases, BESIL 8230 may fail to cure to optimum properties when in contact with certain plastics or rubbers. Cleaning the substrate with solvent or baking slightly above the cure temperature will normally eliminate the problem. Certain chemicals, curing agents and plasticisers can inhibit cure. These include:
- Organotin compounds - Silicone rubber containing organotin catalysts
- Amines, urethanes, amides and azides.
PACKAGING AND STORAGE
• When stored at or below 35°C in the original unopened containers, this product has a usable life of 12 months from the date of production.
• Have to test if expired.
