These paste-consistency silicone sealants can be used in thickness up to 6mm (1/4 in.) for bonding and sealing, joining metals and plastics, and electrical insulation. For applications requiring sealant thickness greater than 6mm (1/4 in.), Momentive Performance Materials one-component, addition cure or two-component silicone rubber compounds are recommended.
- Product Safety, Handling and Storage
Customers should review the latest Safety Data Sheet (SDS) and label for product safety information, safe handling instructions, personal protective equipment if necessary, emergency service contact information, and any special storage conditions required for safety. Momentive Performance Materials (MPM) maintains an aroundthe- clock emergency service for its products.For product storage and handling procedures to maintain the product quality within our stated specifications, please review Certificates of Analysis, which are available in the Order Center. Use of other materials in conjunction with MPM products (for example, primers) may require additional precautions. Please review and follow the safety information provided by the manufacturer of such other materials.
- Bond Strength Development
In addition to the effects of temperature and relative humidity, development of maximum bond strength will depend on joint configuration, degree of confinement, sealant thickness and substrate porosity. Typically, sufficient bond strength will develop in 4-6 hours for RTV5810 adhesive sealants to permit handling of parts. Stress should not be applied to the bonded joint until full adhesive strength has developed. Always allow maximum cure time available for best results.
Non-corrosive Properties
RTV5810 series adhesive sealants generally comply with the non-corrosive requirements of MIL-A-46146B on aluminum and steel. When allowed to cure in enclosed conditions, these sealants will discolor sensitive metals such as copper and brass. When allowed to cure in non-enclosed conditions, these sealants may discolor sensitive metals such as copper and brass but only when in direct contact.- Cure Time Cycle
These adhesive sealants may be applied directly to clean or primed substrates. Where broad surfaces are to be mated, the sealant should be applied in a thin, less than 6mm (1/4 in.) diameter bead or ribbon around the edge of the surface to be bonded.
The cure process begins with the formation of a skin on the exposed surface of the sealant and progresses inward through the material. Due to its fast curing nature, at 77°F/50% RH RTV5810 adhesive sealants will form a skin and become tack free typically in 15-20 minutes. Once the tack free skin has begun to form, further tooling of the adhesive sealant is not recommended.
As the adhesive sealant cures, methly alcohol and residual ammonia vapors are released from the sealant surface. Because these adhesive sealants cure by reacting with atmospheric moisture, higher temperatures and humidity generally will accelerate the cure process while lower temperatures and humidity generally will slow the cure rate.
Exact cure time will depend on temperature, humidity, sample thickness and sealant configuration. Since cure time increases with thickness, use of these adhesive sealants should be limited to section thickness of 6mm (1/4 in.).
- Processing Recommendations
Surface Preparation
RTV5810 series sealants will bond to many clean surfaces without the aid of primers. These surfaces normally include many metals, glass, ceramic, silicone rubber and
some rigid plastics. Surfaces should be thoroughly cleaned with a suitable solvent to remove dirt, oil, grease and surface contaminants. The surface should be wiped dry before applying the adhesive sealant. When solvents are used, proper safety precautions must be
observed.
Due to substrate variability, an evaluation should be made to determine whether acceptable bond strength develops for each specific application. For difficult-to-bond substrates, use of a primer is suggested. SS4004P, SS4044P and SS4179 primers from Momentive Performance Materials may be considered for use with these sealants. Complete information and usage instructions for these primers are contained in a separate product data sheet.- Cleanup and Removal
Before cure, solvent systems such as naphtha are typically most effective. After cure, selected chemical strippers that will remove the silicone rubber are available from other manufacturers. Specific product information may be obtained on request.
