Product Description

Metal Surface Bonding Medium Viscosity Anaerobic Adhesive (SA4641)

SA4641, is one-component, medium strength, medium viscosity
Anaerobic retaining sealant, It cures when confined between
Two close fitting metal surfaces in the absence of air.

Usage
Used for bonding of cylindrical fitting parts, particularly where disassembly is required of service operations; For the retention of bearings onto shafts and into housings.

Operation
1. For the better results, clean all the surfaces(external and internal) with our A6755 cleaning
And allow to dry and oil.
2. For slip fitted Assemblies, apply adhesive around the leading edge of the pin and the inside of the collar and use a rotating motion during assemble to ensure good coverage; For Press Fitted Assemblies, apply adhesive thoroughly to both bond surfaces and assemble at high press on rates; For shrink Fitted Assemblies, the adhesive should be coated onto the pin, the collar should then be heated to create sufficient clearance for free assembly.
3. Assembled parts should not be disturbed until sufficient handing strength is achieved

Founded in DEC. 2003, SEPUNA has been engaged in researching, manufacturing and marketing automobile sealant and adhesive for 9 years.

Since the foundation, SEPUNA Chemical has been focusing on adhesive's researching and application. Then in 2005, We acquired PUNADE technology which is from Switzerland.

Within 9 years, SEPUNA mainly develops Silicone, Polyurethane and Epoxy resin adhesives. And in the future, we will enlarge our line to Unsaturated, Natural and Acrylic Resin adhesive.

After 9 years' improvement, by the keep researching and innovation, SEPUNA is already a mature adhesive supplier with the core competitiveness.
