Geltek sealant strip environmental Gaskets                 

Geltek sealant strips are pre-cured silicone gels

Geltek sealant strips are a line of pre-cured silicone gels that are die-cuttable solid gels with liquid characteristics. 

  • They are easy to compress and 'self tacky' allowing gaskets to 'wet out to surfaces.  Geltek gaskets won't crack or soften due to temperature, time or vibration, and as geltek is 'self-healing', it is ideal for wire sealing.  Geltek gaskets are easily applied and re-worked, and don't require application equipment to install.

Geltek is an excellent low pressure gasket that seals surface irregularities and provides good corrosion protection that prevents moisture from attacking metals.

  • Moisture and electrolytes are displaced by the soft gel stopping galvanic corrosion of dissimilar metal surfaces.
  • Geltek environmental gaskets are good in field applications with periodic repair, and are stable over the application life.     geltek video

Geltek Rope Gaskets:    
• provides shielding against high levels of EMI

EMI Geltek Rope Gaskets • environmental and pressure sealing against water ingress and electrical grounding in a variety of electronics and communications applications Extensive salt fog tests have shown Geltek silicone gel materials provide an effective barrier against galvanic corrosion.

  • Gel surrounds the conductive wire mesh of the gaskets, and isolates the metal substrate to gasket protect contact points from corrosive elements
  • The unique wire mesh/silicone gel construction also ensures that the electrical resistance of the wire mesh will not increase significantly due to corrosion, and the surface wetting action of the geltek minimizes intermetallic corrosion between gasket and substrate, and ensures dependable EMI shielding and environmental sealing.
  • Standard geltek gaskets feature wire mesh made of Monel®, ideal for EMI shielding and low cost.
