Product Description

 

Product Description

SIWAY 8230 is a two-part addition cure RTV. Comparing to condensation cure system, BESIL 8230 has following features:

• long potting life, But rapidly cured under heat.
• Contain all the ingredients neededfor cure with no by-products from the cure mechanism. Deep-section or confined cures are
• Require nopost-cure

 FEATURES

 

• 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.

Substrate preparation

All surfaces should be cleaned and degreased with a suitable solvent prior to potting. Care should be taken to ensure that all solvent is removed. For best adhesion, coat surfaces with BGX-706, following the instructions and precautions given for use of these products.

Mixing

• SIWAY 8230 is supplied in lot matched kits consisting of Part A and Part B in separate containers. During long periods of storage, someof the filler may settle at the bottom of the containers and should be individually homogenised prior to

How to apply

• The two components should be thoroughly mixed using a weight ratio of 1:1 until the mixture has a uniform colour. Vacuumde-airing is recommended. A residual pressure of 10-20 mm mercury applied for 5-10 minutes will sufficiently de-air the
• Being careful to avoid air entrapment, apply the encapsulant. Vacuum encapsulation is recommended for complex geometries. For information on appropriate dispensing equipment for your application, please contact Beginor marketing department.

Curing

SIWAY 8230 should be cured using one of the following recommended schedules:

8 hours at 23°C, or 60 minutes at 70°C, or 30 minutes at 100°C, or 15 minutes at 150°C. Large components and assemblies may require longer times in order to reach the curing temperature
