Carboline Thermaline 450 is a two-component, highly cross-linked, glass-flake filled polymer that offers exceptional barrier protection and resistance to wet/dry cycling at elevated temperatures. Suitable for insulated or uninsulated pipes, stacks and equipment operating up to 232°C.

This coating provides excellent resistance to corrosion, abrasion and permeation, and its novolac-modification resists severe chemical attack. This extreme performance product has decades of performance and is recommended for CS-1,3,4 and SS-1,2,3 systems of NACE SP0198 Standard Practice for coatings to control corrosion under insulation (CUI).

• Ambient-temperature cure
• VOC compliant to current AIM regulations
• Eggshell finish

Product Specification

Drying Times

• These times are based on 8.0-10.0 mil (250 micron) 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, can cause discolouration, and may result in a surface haze. Any haze or blush must be removed by water washing before recoating.
• During high humidity conditions, it is recommended that the application be done while temperatures are increasing
• If the maximum recoat time is exceeded, the surface must be abraded by sweep blasting prior to the application of additional coats

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
• Special application techniques may be required above or below normal application conditions

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

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
