Description
M-CERAMIC 700 - Polyurethane Impact Resistant Coating
Is a flexible high build solvent-free Polyurethane Imact Resistant Coating designed for applications subject to impact, wear and abrasion from slurries and aggregates ect….
The material is designed to be applied as a multi coat system, with a minimum cured coating thickness of 1.0mm. This can be achieved by using a brush, roller or squeegee typically 2 x 500 micron coats is achievable on horizontal surface. For vertical surfaces 3 coats may be required.
Application Guide
- All oil and grease must be removed from the surface using an appropriate cleaner such 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 surfaces must be coated before gingering or oxidation.
- 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.
- All surfaces must be repaired before gingering or oxidation occurs.
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 10°C or less than 3°C above dew point.
- Transfer the contents of the Activator unit into the Base container.
- Using a slow speed electric paddle mixer, mix the 2 components together until the material is streak free.
- Once mixing is complete, use the mixed coating as soon possible after mixing.
Use all mixed material within 15 minutes at 20°C.
- Pour the mixed material into a paint kettle or paint tray (this will maximise the usable life)
- Using a 50mm synthetic brush, stripe coat all edges, joints & corners.
- Once the stripe coat has cured sufficiently and is capable of being overcoated, apply the basecoat to all surfaces at minimum 350 microns.
- Once the basecoat of material has cured sufficiently, approximately 6-8 hours at 20°C, apply the intermediate coat to all surfaces at a minimum 350 microns.
- Once the intermediate coat has cured sufficiently, approximately 6-8 hours at 20°C, apply the topcoat to all surfaces at a minimum 350 microns.
- Minimum finished coating thickness needs to be in excess of 1000 microns.
