This product MUST be purchased/used in conjunction with its manufacturer specified base or activator/hardener.

Carboline Thermaline 440 Primer (formerly Thermaline 400 EU) is part of the high performance, immersion grade coating system which has excellent resistance to wet/dry cycling conditions at elevated temperatures. Used to protect steel substrates under thermal insulation.

Please note this product is one part of a three-pack system which MUST be purchased/used together with Carboline Thermaline 400 EU Finish.

Use this primer directly onto prepared steel before applying Thermaline 400 EU.

Features and Benefits

• Temperature resistant up to 204ºC
• Very good flexibility
• Excellent overall chemical resistance
• Very good abrasion resistance
• Easily applied by spray
• Acceptable for use over stainless steels
• Semi-gloss primer

Product Specification

Drying Times

• These times are based on the recommended dry film thickness. Excessive film thickness or inadequate ventilation conditions after application require longer dry times and will cause premature failure in extreme cases
• Maximum recoat time is normally 60 days. If exceeded and depending on curing time and exposure, pre-treatment may be required prior to overcoating. Contact Rawlins on Tech - 0113 2455450 (option 2) or [email protected] for further information
• EXCESSIVE HUMIDITY OR CONDENSATION ON THE SURFACE DURING CURING MAY RESULT IN SURFACE HAZE OR BLUSH; ANY HAZE OR BLUSH SHOULD BE REMOVED BY WASHING WITH WATER BEFORE RECOATING

Surface Preparation

General

• Surface must be clean and dry
• Employ adequate methods to remove dirt, dust, oil and all other contaminants in accordance with Standard SSPC-SP1

Steel

• Abrasive blast to ISO 8501-1 Sa 2½ to obtain a 35 – 75 µm blast profile
• Alternative Ultra High Pressure water jetting (UHPWJ) to the standard of min. CHB2 M, provided existing surface profile (e.g. maintenance projects)

Stainless Steel

• Blast cleaning with non-metallic abrasive to obtain 25 – 50 µm profile

Application Methods

Application Conditions

• 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
• Do not apply when the surface temperature is less than 3°C above the dew-point

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 safety data sheet for this product and use personal protective equipment as directed
• 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
• In addition to ensuring proper ventilation, appropriate respirators must be used by all application personnel

Caution

• This product contains flammable solvents
• Keep away from sparks and open flames
• All electrical equipment and installations should be made and grounded in accordance with regulations
• In areas where explosion hazards exist, workmen should be required to use nonferrous tools and wear conductive and nonsparking shoes

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