Carboline Rustbond FC is two-component, cross-linked penetrating primer/sealer with excellent wetting properties. It is highly flexible with good chemical and solvent resistance and accept a variety of topcoats. Recommended use as primer/sealers for marginally prepared steel and over old coatings. Its excellent wetting properties allows it to penetrate rust and discontinuities in existing coatings and provide a firm anchorage for a variety of topcoats.

The thixotropic character of Rustbond FC reduces run off, ensuring that the edges of existing coatings are encapsulated thus reducing undercutting and peeling. It may also be used as a tie-coat for coatings that exceed their “recoat window.” Consult Carboline Technical Services Department for specific recommendations.

Product Specification

Drying Times

• These times are based on 50% relative humidity and 25-50 microns 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

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 safety data sheet 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 respirator

Caution

• THIS PRODUCT EXOTHERMS AT THE END OF ITS POT LIFE
• Any unused quantities will become extremely hot. Immediately spread out on an appropriate surface or add sand or other suitable heat sink to the unused material to reduce the severity of exotherm
• Take appropriate precautions against breathing fumes
• 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
• n areas where explosion hazards exist, workmen should be required to use non-ferrous tools and wear conductive and non-sparking shoes

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