Catalog No. 80-599-83EA

Supplier: Sigma Aldrich 8059983EA

Description

MilliporeSigma Sigma Organics products encompass a wide range of quality reagents, solvents, catalysts, and building blocks for organic synthesis. From benchtop discovery to process development and scale-up, Sigma Organics solutions are built to meet the needs of synthetic chemists.

Features:Two-part: 1:1 mixing ratio (pre-weighed).Low viscosity.Room temperature or heat accelerated cure.Rapid, versatile cure processing controlled by temperature.Moderate thermal conductivity.Enhanced flow and fill in narrow spaces and around complex geometries.Provides stress relief in applications where hard, rigid encapsulants can cause damage during thermal cycling.It can be considered for uses requiring added flame resistance and Mil Spec applications.How to use:Mixing: SYLGARD(R) 170 Silicone Elastomer is supplied in a dual syringe applicator with the static mixer consisting of Part A and Part B. The two components pre-weighed with 1:1 mixing ratio in the syringe applicator should be thoroughly mixed until the mixture has a uniform color. Vacuum de-airing is recommended. A residual pressure of 10-20 mmHg applied for 5-10 minutes will sufficiently de-air the material.Curing: SYLGARD(R) 170 Silicone Elastomer should be cured using one of the following recommended schedules:24 hours at 25°C or25 minutes at 70°C or10 minutes at 100°C.Large components and assemblies may require longer times in order to reach the curing temperature.Certain chemicals, curing agents and plasticizers can inhibit cure. These include:Organo-tin compounds.Silicone rubber containing organo-tin catalysts.Sulfur, polysulphides, polysulphones and other sulphur containing materials.Amines, urethanes, amides and azides.For most uses, silicone encapsulants should be operational over a temperature range of -45 to 200°C (-49 to 392F) for long periods of time.SYLGARD(R) 170 Silicone Elastomer is suitable for use as an encapsulant or potting material.Potential applications:Power suppliesConnectorsSensorsIndustrial controlsTransformersAmplifiersHigh voltage resistor packsRelaysSylgard is a registered trademark of The Dow Chemical Company or an affiliated company of Dow
