Carboline Plasite 7122 is a two-component, lining-grade epoxy has wide chemical resistance and is suitable for use as a chemically resistant coating for aggressive atmospheric exposures or as a lining for a variety of chemical exposures. It is suitable for use in food-grade service where product purity (taste and odour) are critical. It has excellent abrasion and thermal shock resistance.

Product Specification

Drying Times

• The cure schedule above is for ambient applied and cured material at 50% RH

• The chart above outlines the cure for service (immersion) times when the Force Cure schedule below is followed

Force Cure

• NOTE: Temperatures listed for 130°F and above are for force cure
• Force curing at elevated temperature will increase resistance to certain exposures. When exposure is severe, force curing is recommended to obtain maximum resistance and service life
• Allow an air-dry time of 2-5 hours @ 70-100°F (21-37°C) before heat curing. After air drying the substrate temperature should be raised by approximately 30°F (15°C) each 30 minutes until the desired force cure temperature is reached
• Final cure may be checked by exposing coated surface to MIBK for ten minutes. If no dissolving and only minor softening of film occurs the curing can be considered complete. The film should reharden after exposure if cured

Surface Preparation

Steel

• Immersion Service or Aggressive Chemical Exposures (Spill/Fume)
• Abrasive clean to an SSPC-SP10 or NACE No. 2 (Near-White metal surface)
• Profile: 1-3 mils (25-75 microns)
• Non-Immersion (Atmospheric)
• Preferred: SSPC-SP6; Where abrasive blasting is not permitted or practical, clean per SSPC-SP3 to yield a rough (non-polished) surface.

Galvanised Steel

• Contact Rawlins on Tech - 0113 2455450 (option 2) or [email protected]

Aluminium

• Surface shall be clean and grease free with a blast produced anchor pattern or “tooth” as described earlier under steel
• For immersion, blasting with sharp grit followed by the chemical surface treatment is required

Concrete or CMU

• Contact Rawlins on Tech - 0113 2455450 (option 2) or [email protected] for recommendations

Application Methods

Health and Safety

Clean Up

• Use Carboline Thinner 71
• In case of spillage, absorb and dispose of in accordance with local applicable regulations

Safety

• Observe the precautionary notices on the container label, and read the Material Safety Data Sheet before use
• Employ normal workmanlike safety precautions

Ventilation

• When used in enclosed areas, thorough air circulation must be used during and after application until the coating is cured.
• The ventilation system should be capable of preventing the solvent vapor concentration from reaching the lower explosion limit for the solvents used
• User should test and monitor exposure levels to ensure all personnel are below guidelines
• If not sure or if not able to monitor levels, use MSHA/NIOSH approved supplied air respirator

Caution

• Fire and explosion hazards: This product contains less than 1% volatile components, however, vapours are heavier than air and can travel long distances, ignite and flash back
• Eliminate all Ignitions sources. Keep away from sparks and open flames
• All electrical equipment and installations should be made and grounded in accordance with applicable local regulations
• In areas where explosion hazards exist, workers should be required to use non-ferrous tools and wear conductive and non-sparking shoes

• Refer to the product data sheet and safety data sheet in the attachments section above for further details.
