Acid Resistant Epoxy Laminating Resin
CPR 603 Acid Resistant Epoxy Laminating Resin is a high performance two pack Epoxy resin, having exceptional resistance to aggressive acids, solvents and alcohols e.g. 96-99% Sulphuric acid, Methyl Ethyl Ketone, and Methanol.
The product has a low viscosity and rapid curing characteristics, even at low temperatures.
- Outstanding chemical resistance
- Tough, durable and abrasion resistant
- Excellent mechanical properties
- Clear, but may be readily pigmented
- Low temperature cure
- Rapid curing characteristics
- Convenient 2:1 volume mix (Base to Curing Agent)
Directions for Use
Surface Preparation Concrete
- Concrete shall be a minimum of 21 days old and/or the residual moisture content shall be below 6%.
- Ensure that the concrete is clean and free from dust, laitance, grease, oil, curing compound and existing paint finishes, etc.
- Blow holes and defective concrete shall be made good using a proprietary repair compound e.g. CPR 719 -Epoxy Concrete Patch Repair Mortar or CPR 726 Concrete Re-surfacer.
- Suitable mechanical treatment such as vacuum grit blasting is the preferred treatment prior to application as this ensures a mechanical ‘key’ for the coating.
Surface Preparation Steel
- Steel surfaces shall be grit blasted to a nominal Sa 2.5 Swedish standard.
- All dust and grease shall be removed prior to coating application.
- Pour the contents of the CURING AGENT container into the BASE container and thoroughly mix, preferably by mechanical means until a uniform colour is achieved.
- Wet out the substrate with CPR 603 Acid Resistant Epoxy Laminating Resin, applying by brush or roller.
- Soak the reinforcement mesh with CPR 603 Acid Resistant Epoxy Laminating Resin and apply to the wetted out substrate.
- Ensure that no air is occluded, spike rollering if necessary.
- Wet out any dry spots with more mixed resin.
- Should a coloured finish be required, then a suitable pigment may be incorporated prior to application.
- A clear top coat may be applied following curing of the underlying system.
- Clean equipment with CPR 200 – Tool Clean Solvent prior to curing of the coating.
- Allow to cure for a minimum of 4 hours @ 20°C prior to overcoating or light foot traffic.
- Allow a minimum of 5 days cure @ 20°C for optimum chemical resistance.
