Selection & Specification Data Generic Type

Single package silicone finish

Description

High-performance finish for areas exposed to extreme temperatures. Suitable for service from 400°F-1000°F (204°C-538°C) Color stability at maximum temperature will depend on color selected. Requires heat curing.

Features

Color

Finish

• Resistant to severe thermal shock • Provides outstanding long-term performance when applied over Carbozinc inorganic zinc primers • Air-dries to touch and provides barrier protection prior to heat curing (full film physical properties occur after heat curing) Available in the following stock colors: Black (C900) 1000°F (538°C) Continuous Black allow surges to 1200°F (649°C) Gray (C705) 750°F (399°C) All other colors are made to order and have minimum temperature resistance of 750°F (399°C). See separate data sheet for aluminum (Thermaline 4700 Aluminum).

Substrates & Surface Preparation General

Surfaces must be clean and dry. Employ adequate methods to remove dirt, dust, oil and all other contaminants that could interfere with adhesion of the coating.

Steel

Follow surface preparation for recommended or specified primer. When using direct to steel surfaces abrasive blast to SSPC-SP10 with a 0.5 to 1.5 mil (12-37 microns) surface profile.

Aluminum

Sweep blast cleaning (SSPC-SP7) is recommended.

Stainless Steel

Abrasive blast to achieve a 0.5 to 1.5 mil (12-37 microns) surface profile.

Mixing & Thinning Mixing

Power mix until uniform in consistency. Avoid excessive air entrapment.

Thinning

Normally not required. May be thinned up to 12.8 oz./gal. (10%) by volume with Thinner #235 for “hot” applications exceeding 150°F (66°C). Use of thinners other than those supplied or recommended by Carboline may adversely affect product performance and void product warranty, whether expressed or implied.

Gloss Initial (Flat after heat curing)

Primer

Inorganic zincs. None needed for stainless steel or aluminum.

Dry Film Thickness

2.0 mils (51 microns) per coat Do not exceed 2.0 mils in a single coat. Two coats are recommended over stainless steel and one or two coats over inorganic zincs.

Solids Content

By Volume 48% +/- 2%

Theoretical Coverage Rate

Topcoats

Use DeVilbiss P-MBC, E-needle and tip, and a 704 air cap or equal. Use adequate air volume for proper equipment operation. Hold gun 10-12” from the surface and at right angles. Overlap each 50%. Apply 4.0 wet mils to obtain desired dry film.

Brush & Roller (General)

Recommended for touch up of small areas or where spray application is not permitted. Avoid excessive rebrushing or re-rolling will create a non-uniform appearance.

Brush

Use a medium bristle brush.

Roller

Use a short-nap mohair roller cover with phenolic core.

Application Equipment Guidelines Listed below are general equipment guidelines for the application of this product. Job site conditions may require modifications to these guidelines to achieve the desired results.

• Do not use for immersion service. • Do not exceed thickness recommendation. • Excessive film thickness may result in blistering and delamination when the temperature is increased.

Spray Application The following spray equipment has been found (General) suitable for application of this material. Conventional spray application is preferred. Note: Different application procedures or methods will result in streaky or non-uniform appearance with aluminum containing products.

Application Conditions Condition Minimum Maximum

Material 55 °F (13 °C) 95 °F (35 °C)

Surface Ambient 40 °F (4 °C) 40 °F (4 °C) 300 °F 120 °F (49 °C) (149 °C)

Humidity 0% 90%

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.

Thermaline 4700 Curing Schedule Surface Temp. & 50% Relative Humidity 75 °F (24 °C)

Dry to Handle

Dry to Topcoat with Itself

Dry to Touch

8 Hours

4 Hours

1 Hours

These times are based on a 2.0 mil (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. Excessive humidity or condensation on the surface during curing can interfere with the cure, can 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. *Dry to handle (thumb-twist test). Final hardness and ultimate film properties are not reached until heat curing has been achieved. Final cure: To obtain optimal properties, must be cured at 400°F. After a 2 hour flash off at 75°F, allow temperature to increase slowly to 400°F. Hold at 350°F to 450°F for 2 hours. The coating may then be placed in service.

Cleanup & Safety Cleanup

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. 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 respirator.
