Bund Coat 2 Chemical Resistant Coating - CPR 612 - CPRL

Description

Bund Coat 2 – Chemical Resistant Coating

CPR 612 – Bund Coat 2 – Chemical Resistant Coating is a two pack Epoxy coating which provides protective and decorative properties to concrete and other substrates. The material is supplied as a two pack system, comprising pre-weighed amounts of BASE and CURING AGENT. After mixing together, an easily applied chemical and abrasion resistant finish is produced. A slip resistant finish may be achieved by broadcasting an appropriate aggregate.

Typical Properties

Solvent free, low odour
Very good chemical resistance
Excellent adhesion to concrete and other substrates
High build
Tough and durable
Easily applied
Hygienic and easily cleaned
Slip resistant options

Directions for Use

Surface Preparation

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 702 – Epoxy Bonding Adhesive.
Block work shall be sealed using CPR 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.

Mixing

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.

Application

Apply by brush, roller or airless spray at a nominal rate of 0.25 to 0.3kg/m².
After a minimum of 14 hours and before a maximum of 48 hours, apply a second coat at the same rate.
Should a non-slip finish be required, then broadcast an appropriate aggregate such as Quartz or Dynagrip, immediately after the first coat.
Brush off excess aggregate the following day, prior to applying the second coat.

Equipment Cleaning

Clean equipment with CPR 201 – Tool Clean Solvent prior to curing of the coating.

Curing

Allow to cure for a minimum of 24 hours @ 20°C prior to light foot traffic access and 48 hours @ 20° prior to vehicular trafficking.
7 days cure @ 20°C is recommended prior to exposure to chemicals.
Lower temperatures will extend the curing time.

Storage and Shelf Life

Store in dry conditions, out of direct sunlight, at temperatures between 10°C and 25°C.
CPR 612 – Bund Coat 2 – Chemical Resistant Coating has a minimum shelf life of 12 months when stored in original, unopened containers in accordance with manufacturer’s instructions.

Packaging

CPR 612 – Bund Coat 2 – Chemical Resistant Coating is supplied in 5kg and 15kg packs.

Coverage

A 5kg pack is sufficient to treat 8.3-10.0 m2 of surface with the recommended two coat treatment, providing an overall d.f.t. of 400-480 microns.
