Carboline Thermaline 4900 Aluminium is a single package, air-dried coating available in colours and suitable for high temperature exposures up to 273°C. Air-drying characteristics allow for faster handling of in-shop applications than with other high-temperature coatings. Heat cure above 149°C is recommended and will impart added strength and integrity to the coating.

Features and Benefits

• Temperature resistance up to 273°C
• Air-dried curing capabilities
• Single-coat application
• Excellent resistance to thermal shock
• Good weathering and colour stability

Product Specification

Drying Times

• These times are based on a 2.0 mils (50 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
• While Thermaline 4900 is an ambient temperature cure coating, optimum performance properties are achieved when final heat cure occurs at 149°C after 3 hours
• After a 2-hour flash off at 24°C allow temperature to increase slowly to 149°C and hold it there for approximately 3 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
• Special application techniques may be required above or below normal application conditions
• The alignment of aluminium flakes in aluminium filled finishes is very dependent on application conditions and techniques
• Care must be taken to keep conditions as constant as possible to reduce variations in final appearance
• It is also advisable to work from a single batch of material since variations can occur from batch to batch

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 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

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, workers should be required to use non-ferrous tools and wear conductive and non-sparking shoes
