Description
M-RUBBER 101 – Multi Surface Rubber Primer
This single component, easy to use, solvent free abrasion resistant urethane elastomer has been specifically developed as an abrasion resistant lining for repairs to a wide range of rubber surfaces such as nitrile, neoprene & natural rubber.
Typical Uses
- Used as sealer for Gaskets
- Lining of process equipment such as chutes, hoppers fans and pumps
Please contact us to discuss your project before purchasing this material to confirm suitability.
Application Guide
- All oil and grease must be removed from the surface using an appropriate cleaner such as MEK or similar type solvent.
- All surfaces must be abrasive blasted to ISO 8501/4 Standard SA2.5 (SSPC SP10/ NACE 2) minimum blast profile of 75 microns using an angular.
- Once blast cleaned the surface must be degreased and cleaned using MEK or similar type solvent.
- All oil and grease must be removed from the surface using an appropriate cleaner such as MEK.
- All surfaces must be mechanically abraded using handheld grinders to ISO 8501/4 ST3 (SSPC SP3 ST3).
- Once abraded, the surface must be degreased and cleaned using MEK or similar type material.
PLEASE NOTE: Soluble salt contaminated surfaces the substrate must be pressure washed with clean water and checked for salt contamination this process may need to be repeated several times.,
- Remove any surface contamination and degrease with MEK.
- Use a suitable carding tool or MBX bristle blaster to roughen the surface before brushing away any debris.
- Once all surfaces, metallic or rubber have been prepared, apply a Multi-surface Primer to all surfaces with a stippling action avoiding ponding. Leave to cure until touch dry and for a minimum of 20 minutes at 20°C (68°F).
Prior to mixing please ensure the following:
- The base component is at a temperature between 15-25°C.
- Do not apply the material when the ambient or substrate temperature is below 5°C.
- M-RUBBER 101 is supplied as a single component liquid, shake well before use.
