Carboline Thermaline 4000 is a high heat polymer coating used for the protection of equipment operating at elevated temperatures. It is typically used over Carbozinc® inorganic zinc primers for outstanding corrosion protection and heat resistance. The combination of the zinc primer with this finish provides exceptional performance in durability. Unlike most high temperature silicone-based technologies with soft films, Thermaline 4000 does not require a heat cure for film forming properties. It cures hard rapidly under ambient conditions (humidity greater than 30%).

Product Specification

Drying Times

• These times are based on recommended coverage rates
• Curing under low humidity conditions will extend times
• Final cure will depend on humidity levels; but generally overnight cure (18-24 hours) is sufficient prior to placing in high-heat service

Surface Preparation

Application Methods

Application Conditions

• Industry standards are for substrate temperatures during application to be 3°C above the dew point
• This product does not require heat-curing; but it does require moisture to complete its final cure. Use water mist if humidity is below minimums

Health and Safety

Clean Up

• Use Thinner 2 or Acetone
• 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 SDS for this product
• Employ normal workmanlike safety precautions
• Use adequate ventilation
• Keep container closed when not in use

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 insure all personnel are below guidelines.
• If not sure or if not able to monitor levels, use MSHA/NIOSH approved supplied air respirator

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