Detail

  • Silicone durability, cured silicone rubber exhibits excellent long term resistance to natural weathering including: extreme temperatures, ultraviolet radiation, rain and snow, with negligible change in elasticity.
  • Primerless adhesion, attains strong bonds to many conventional substrates and finishes without the need of a primer.
  • Low pumping viscosity, decreased stress on equipment can lead to longer pump life and reduced maintenance costs.
  • Fast adhesion build, enhances early stability of assembled parts.
  • Protective glazing, an excellent combination of strength, flexibility and tear resistance to help counter the higher forces created by hurricane, impact and blast loads.

Tech Spec

Basic Uses

Preparation

  • Recommended mixing ratio is 10-13:1 (by volume) or 12:1 (by weight).
  • Prior to production, hand-mix desired ratio of the base and catalyst to check that desired snap time is achieved. Check also that curing is achieved within reasonable time.
  • This will validate the material performance separately from production equipment.
  • This procedure should be done daily to account for daily changes in atmospheric condition.

Application Instruction

  • Clean all surfaces of all dirt, oils and any foreign matters using IPA, MEK, toluene or other suitable solvents. Apply the sealant within 2 hours after cleaning.
  • IKASEAL 999SG should be mixed and dispensed using specialized two-part sealant dispensing machine designed to meter, thoroughly mix and dispense precise proportions of both components at proper pressure to give homogenous, air-free material.
  • Hand mixing of the base and catalyst component should be done only when performing preliminary testing.
  • Perform butterfly test to ensure proper mixing. The material should show solid homogenous black color, free of any swirling or marbling of colors. If incomplete mixing is observed, cease operation and adjust equipment until proper mixing is attained.

Limitations

  • Not to be used as the primary seal insulating glass units.
  • Do not expose to acetic acid evolved by adjacent sealants.
  • Not recommended for water immersion applications.

Precautions

  • Because the catalyst can react with atmospheric air, please do not leave it exposed for prolonged period of time.
  • During equipment shutdown, flush dispensing and mixing line with uncatalyzed base to minimize sealant buildup.
  • Material Safety Data Sheets (MSDS) are available upon request.
