M952 - Black self-extruding silicone sealant for cars

INSTRUCTIONS: 1.Apply to clean, degreased and dry surfaces. 2. Assemble the parts within 5 minutes by pressing firmly. 3. Allow vulcanization to complete for a few hours before subjecting parts to heavy duty or high temperatures.

Benefits: It allows you to directly form instant gaskets in a simple and practical way using the pressurized and therefore self-extruding cartridge. Holds heat, pressure and lubricating oil. Withstands bending movements and torsion of the sealing flange.

- Silicones used as gaskets serve to form an airtight seal between mating parts, preventing leaks of liquids or gases. The "instant" type gaskets formed directly on site (formed in place, FIP) are made with silicone spread on one of the two parts of the joint. When assembled, the product fills small cavities, gaps and surface imperfections, subsequently forming a long-lasting seal.

- The two most used types of products are RTV (Room Temperature Vulcanizing) silicones, which vulcanize at room temperature, and so-called anaerobic compounds, which polymerize in the absence of oxygen, when the pressure of the two parts of the joint removes the air . RTVs are suitable for joints with large gaps and stamped metal parts where the flange deflection is greater, and anaerobic ones are more suitable for joints with small gaps and assemblies of rigid metal-to-metal castings.

- The RTV silicone paste must be spread like a bead along the perimeter of the surface of one of the two flanges to be joined. Both parts must be clean. Assembly must be carried out within 5 minutes. Then, by applying pressure, the paste is distributed so that it completely fills the joint until it overflows outside. The adhesive bond thus developed must be left to rest while the material vulcanises. The completion time of vulcanization depends on the ambient temperature and humidity. It is recommended not to subject the joint to strong stress immediately. A rest of a few hours is essential before the joint is subjected to stress.

- A high quality product, M952 is a one component adhesive/sealant made from 100% pure RTV silicone with no fillers. It remains flexible once vulcanization is completed.

- Acts on various materials: metals, plastics, fiberglass, rubber, etc.

- Withstands high temperatures, with max. momentary temperatures of 300°C
