SILCAST™ SC-417

1 of 5 products in this brand
SC-417 is a two-part, low viscosity, clear silicone which will cure at room temperature or at elevated temperatures. The cured elastomer is suited for electrical/electronic potting and encapsulating applications and provides environmental protection. It is readily pourable and can cure from room temperature to 200°C. The cured resin has a very good flexibility with excellent electrical properties and high temperature resistance.

Applications & Uses

Cure Method
Typical Application

Potting and encapsulating of:

  • Equipment modules
  • Power supplies, relays and amplifiers
  • Transformers, coils and ferrite cores
  • Fiber optic waveguide coatings
  • Encapsulation of circuit boards
Instruction for Use
  1. Weigh each 100 grams of PART-A to 100 grams of Catalyst PART-B.
  2. Mix until uniform. Scrape the sides and bottom of container repeatedly during mixing.
  3. Apply to clean bonding surfaces and cure as recommended to achieve the desired properties.
  4. Typical cured properties were determined using recommended cure schedule. Some difference in properties may occur with the alternate or other cure schedules.
Industrial Usage

Practices of good housekeeping, safety and cleanliness should be followed before, during and after use.
