HM-SS5569 Room temperature vulcanizing (RTV) silicone sealant, suitable for replacing gaskets. It is easy to use and meets the requirements for on-site shaping, curing, production, and maintenance. Using a new environmentally friendly formula, this non-toxic and low odor sealing adhesive provides temperature resistance, oil resistance, and corrosion resistance, making it an excellent alternative to traditional gaskets. It is widely used for flat sealing of engines, gearboxes, axle housings in automobiles, motorcycles, ships, and machinery equipment. It is the best solution for solving flat sealing problems during assembly and maintenance.
Previously, solid gaskets such as paper, asbestos, and metal were used for flat sealing. However, these solid gaskets are prone to leakage over time due to stress or infiltration.
To completely solve the problem of leakage, anaerobic sealants or silicone sealants are now being chosen to replace solid gaskets for sealing purposes. This product has excellent adhesive strength, instant sealing, oil resistance, high and low temperature resistance, weather resistance, and pressure resistance.

 

Features

1. Excellent adhesive strength
2. Instant sealing
3. Oil resistance
4. High and low temperature resistance
5. Weather resistance
6. Pressure resistance

Application

Mainly used for flange sealing, with excellent oil resistance and ability to withstand large movement of adhesive joints, such as stamped metal covers (such as timing gear covers, oil pans, engines).

 

Usage Guidelines

1. Pre-treatment: For optimal bonding performance, the surface of the substrate should be clean and free of grease.

2. Adhesive application: Apply a bead of the product on the clean surface of the substrate, assemble the parts within five minutes. Press the parts together to ensure even distribution and full filling of the adhesive.

3. Curing: The adhesive point should be fully cured before bearing heavy loads. The curing speed depends on environmental humidity and temperature.

4. If there is excess adhesive, it can be removed with a non-polar solvent.

 

Storage and Shelf Life

Store the original sealed adhesive in a dry place with a temperature not exceeding 27 degrees.
The storage period is 12 months from the date of production.
