Cold Vulcanizing Solutions offered comprise Cold vulcanizing also known as Non Flammable Cold Vulcanizing solutions. Here, the CONTIBELT 9000 offered is a black color, viscous liquid that has brushing viscosity. As a two component, room temperature curing synthetic rubber based adhesive, when catalyzed using appropriate amount of hardener, it yields high strength adhesion when bonding -
- Rubber to rubber
- Rubber to fabric
- Rubber to steel
- Rubber to PVC
- Urethane
- Fiberglass
- Concrete
With CONTIBELT 9000 formulated after extensive R D efforts, we are able to successfully address diverse process needs of different industry sectors. Further, these cold vulcanizing solutions are also highly popular for applications involving -
- Conveyor belt jointing
- Pulley lagging
- Belt repair
Mixing Ratio:
The mixing ratio involves -
- 100 gms of adhesive per 5 gms of hardener
Application Process:
- Add required amount of hardener with adhesive
- Mix solution properly until uniform coloration occurs
- Use recommended dosage of 5 grams of hardener with 100 grams of adhesive
- The prepared mixture need to be consumed within 2-3 hrs so as to avoid -
- Effect of solvent evaporation
- Thickening of mix because of cross linking that leads to inferior spreading property
- Keep pot covered when not in use as product is highly sensitive to moisture
Benefits:
- Providing higher coverage in a cost effective way
- Providing superior bonding strength, thus ensuring of a quality output
- Allowing more open time that meets production cycle needs
- Provides for uniform performance
- As it does not contain benzene, it saves human life from cancer possibility
Application Procedures - Examples:
Rubber to Steel:
Pre-application Safeguards:
- Metallic surfaces need to be free of oils, grease as well as other contaminants
- Here, it should also be ensured that rust and mill scale are removed through sand blasting process to NACE #2 (for this profile of 2-3 mils is preferred)
- The cured rubber should have all mould release agent removed as well as buffed with stiff bristled wire brush of 24 grit
- This should be done at speed that does not burn the rubber surface
Application:
- Apply first coat to each surface in a scrubbing like motion
- Allow coat to dry for around 1 hour at 25oC
- After required drying time, second coat is applied to each surface
- Let this dry until tacky and then compress both surfaces through stitch down/applying pressure
- Maximum bond strength would develop in around 21 days (however sufficient initial bond strength will be achieved after 24 hours that makes it ready for most services)
Rubber to Rubber:
Pre-application Safeguards:
- Rubber, if cured in sheet form need to be solvent cleaned as well as buffed as described before application of the first coat of adhesive
Application:
- Allow first coat to dry for at least 1 hour or longer
- After required drying time, second coat is applied
- When still tacky, stitch two components together/or apply pressure
Rubber to Other Substrates:
For adherence to other elastomeric materials/special environmental conditions, please undergo trial so as to determine -
- Suitability of product with individual materials
- Determine the preferred method of application
- Brand Continental Belting
- Size As Per Requirement
