Geltek Sealant Strips

1)  Dow Corning® Geltek Environmental Gaskets:

These pre-cured silicone gels 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 good 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 metal.

• 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.

3) Dow Corning® Geltek Rope Gaskets:    
• provide shielding against high levels of EMI
• environmental and pressure sealing against water ingress and electrical grounding in a variety of electronics and communications applications.

Extensive salt fog tests have shown that the Dow Corning Geltek silicone gel material provides an effective barrier against galvanic corrosion. Gel surrounds the conductive wire mesh of the gaskets and isolates the metal substrate-to gasket 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. The surface wetting action of the geltek minimizes intermetallic corrosion between gasket and substrate, and ensures dependable EMI shielding and environmental sealing. Standard Dow Corning geltek gaskets feature wire mesh made of Monel®, ideal for EMI shielding and low cost.
