Outline

Features: Gels are solids with fluid characteristics. They provide mechanical protection and dampening with good cohesion, high instantaneous deformation.

Applications:

  • shock absorption- provide a property range extending from vibration dampening to sound absorption
  • electrical devices- provide low stress protection to delicate components

Description: Gel D200 (PP2-D200) is a temporarily deformable medium penetration gel with typical dimethylsilicone properties and a refractive index of 1.41.

Gel Properties:

  • color: clear
  • refractive index: 1.407
  • penetration: 150-250 mm
  • specific gravity: 0.97

Uncured Properties:

  • form: liquid
  • viscosity: 1000 cSt

Processing:

Gel D200 is a 2-part addition cure system. Each system comprises an “A” part and a “B” part which are mixed in a 10:1 ratio. After thoroughly mixing 10 parts “A” to 1 part “B”, allow mix to de-air. Pot life is 3-4 hours. Pour or syringe around part or into cavity. Cure at 115-120 °C for 30-60 minutes or at room temperature for 48 hours. If the gel is too firm (low penetration), increase the ratio of A to B to 11:1, 12:1 etc.

Shelf life: Six months when stored below 5 °C in sealed containers. Containers should be warmed to 15 °C before opening to reduce condensation of water.

Cautions: Avoid contact with skin and eyes.

Description: Gel D300 (PP2-D300) is a temporarily deformable high penetration gel with typical dimethylsilicone properties and a refractive index of 1.41.

Gel Properties:

  • color: clear
  • refractive index: 1.407
  • penetration: 200-400 mm
  • specific gravity: 0.97

Uncured Properties:

  • form: liquid
  • viscosity: 350 cSt

Processing:

Gel D300 is a 2-part addition cure system. Each system comprises an “A” part and a “B” part which are mixed in a 10:1 ratio. After thoroughly mixing 10 parts “A” to 1 part “B”, allow mix to de-air. Pot life is 3-4 hours. Pour or syringe around part or into cavity. Cure at 115-120 °C for 30-60 minutes or at room temperature for 48 hours. If the gel is too firm (low penetration), increase the ratio of A to B to 11:1, 12:1 etc.

Cautions: Avoid contact with skin and eyes.

Features: Gels are solids with fluid characteristics. They provide mechanical protection and dampening with good cohesion, high instantaneous deformation, and good resilience with a wide range of chemical resistance and refractive index control.

Applications:

  • optical component coating – coupling media and elastomeric seals
  • shock absorption – provide a property range extending from vibration dampening to sound absorption
  • electrical devices – provide low stress protection to delicate components

Description: Gel P065 (PP2-P065) is a temporarily deformable material with excellent low temperature properties and a refractive index of 1.43. It performs as a dielectric gel from 115 to 235 °C.

Gel Properties:

  • color: clear
  • refractive index: 1.430
  • penetration: 60-80 mm
  • specific gravity: 0.99
  • dielectric constant: 2.8

Uncured Properties:

  • form: liquid
  • viscosity (initial mix): 700-800 cSt

Processing:

Gel P065 is a 2-part addition cure system. It is comprised of “A” and “B” parts which are mixed in a 1:1 ratio. After thoroughly mixing 1 part “A” to 1 part “B”, allow mix to de-air. Pot life is 3-4 hours. Pour or syringe around part or into cavity. Cure at 115-120°C for 30-60 minutes or at room temperature for 48 hours. If the gel is too firm (low penetration) increase the ratio of A to B
to 1.1:1, 1.2:1 etc.

Shelf life: 12 months when stored below 25 °C in sealed containers.

Cautions: Avoid contact with skin and eyes.

Description: Gel F065 (PP1-F065) is a temporarily deformable material with fluorosilicone properties, providing fuel-resistant properties and a low refractive index. The one part addition cure system is technically achieved by incorporating a fugitive inhibitor to the catalyzed mix.

Gel Properties:

  • color: clear
  • refractive index: 1.384
  • penetration: 60-80 mm
  • specific gravity: 1.27

Uncured Properties:

  • form: liquid
  • viscosity: 1200-1500 cSt

Processing:

Gel F065 is a 1-part addition cure system. Pour or syringe around part or into cavity. Cure at 100-150 °C for 20-30 minutes. If the gel is too firm (low penetration), FMV-4031 fluorosilicone polymer can be added at 5-20% levels prior to cure.

Shelf life: Six months when stored below 0 °C in sealed containers.

Cautions: Avoid contact with skin and eyes.
