Features and Benefits

• Resistant to severe thermal shock
• Provides outstanding long-term performance when applied over Carbozinc inorganic zinc primers
• Air-dries to touch (full film formation properties occur after heat curing)
• Touch dry in up to 1 hours at 24°C
• Gloss finish

Product Specification

Drying Times

• These times are based on a 51 microns dry film thickness. Higher film thickness, insufficient ventilation or cooler temperatures will require longer cure times and could result in solvent entrapment and premature failure
• Excessive humidity or condensation on the surface during curing can interfere with the cure and may cause discoloration
• During high humidity conditions, it is recommended that the application be done while temperatures are increasing
• If the final cure time is exceeded, the surface must be abraded prior to the application of additional coats
• Full physical properties will be reached when heat curing has been completed
• After a 2 hour flash off at 24°C, allow temperature to increase at a maximum rate of 2°F per minute to 204°C
• Hold at 350°F to 177°C to 232°C for 2 hours

Surface Preparation

Application Methods

Application Conditions

• This product simply requires the substrate temperature to be above the dew point
• Condensation due to substrate temperatures below the dew point can cause flash rusting on prepared steel and interfere with proper adhesion to the substrate

Health and Safety

Clean Up

• Use Thinner 2
• In case of spillage, absorb and dispose of in accordance with local applicable regulations

Safety

• Read and follow all caution statements on this product data sheet and on the MSDS for this product
• Employ normal workmanlike safety precautions
• Hypersensitive persons should wear protective clothing, gloves and use protective cream on face, hands, and all exposed areas

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 respirator

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