SEALING COMPOUND (WITH ACCELERATOR), SILICONE RUBBER, ELECTRICAL

Organization:

Year: 1996

Abstract: This specification covers the requirements for electrical silicone rubber sealing compounds that are not resistant to fuel. These compounds are intended for use in the temperature range of −62 to +204°C (−80 to +400°F).
The sealing compound is furnished in the following types, classes and grades, as specified (see 6.2):
The sealing compound is classified by viscosity of the base compound as follows:
Type I - Low viscosity
Type II - Intermediate viscosity
Type III - High viscosity
The sealing compound is classified as follows:
Class 1 - Fast cure (room temperature 25° ± 1°C [77° ±2°F])
Class 2 - Medium cure (room temperature 25° ±1°C [77° ±2°F])
Class 3 - Slow cure (room temperature 25° ±1°C [77° ±2°F])
Class 4 - Elevated temperature cure 80° ±1°C (175° ±2°F) Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: Commander, Naval Air Warfare Center Aircraft Division, Code 414100B120-3, Highway 547, Lakehurst, NJ 08733-5100, by using the Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter.
The sealing compound is furnished in the following grades:
Grade A - Condensation cure
Grade B1 - ersion resistant, condensation cure
Grade B2 - ersion resistant, addition cure Intended Use: The sealing compound covered by this specification in its cured condition is intended for use on various electrical applications of military weapons systems at temperatures ranging from −62 to +204°C (−80 to +400°F) when potting or encasing electrical and electronic components with an elastomeric medium. This material is used when tear resistance is not critical. The grade A material should not be used for thick sections or in confined areas (see 6.5). The grade B2 addition cure material is used only to repair itself and must not be used to repair grade A or B1 material.

     CAUTION        -       Grade B2 catalyzed material must be vacuum de-aired to eliminate                             voids and porosity due to gas evolution and to achieve maximum                             electrical and physical properties. Care should also be taken to                             avoid mixing air into the material during the addition of catalyst.
