Rustbond
PRODUCT DATA SHEET

S E L E C T I O N & S P E C I F I C AT I O N D ATA
Generic Type Polymeric epoxy amine.

Rustbond is a 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
Description
provide a firm anchorage for a variety of topcoats. Its thixotropic character 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.

MIXING & THINNING

Power mix components separately to break down any gel. Keep the mixing blade at slow speed
and submerged in the product to minimize whipping of air into the material. Scrape the sides of the
Mixing
container occasionally to insure uniformity. Continue to mix for 1-2 minutes. DO NOT MIX PARTIAL
KITS, and do not intermix unpaired components.

Preferred Thinner Uses and Application:

Thinning not normally required but may be thinned up to 9% (12 oz/gal) with Thinner #76.
Thinning
Use of thinners other than those supplied or recommended by Carboline may adversely affect
product performance and void product warranty, whether express or implied.

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.

Spray Application Contact Carboline Technical Service for specific application instructions.
(General)

Brush & Roller Avoid excessive re-brushing or re-rolling. Apply enough material to uniformly wet the surface. Any
(General) puddles formed must be brushed out.

Brush Use a medium bristle brush and distribute evenly using full brush strokes.

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.

Roller Use a medium to long nap roller suitable for solvent base materials to evenly distribute the material.

Condition Material Surface Ambient Humidity
Minimum 60°F (16°C) 70°F (21°C) 70°F (21°C) 0%
Maximum 100°F (38°C) 130°F (54°C) 110°F (43°C) 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.

CURING SCHEDULE
Surface Temp. Dry to Handle Dry to Topcoat Final Cure General
70°F (21°C) 34 Hours 18 Hours 9 Days
80°F (27°C) 22 Hours 12 Hours 6 Days
90°F (32°C) 14 Hours 9 Hours 4 Days
100°F (38°C) 11 Hours 4 Hours 3 Days

* These times are based on 50% relative humidity and 1.0–2.0 mils (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 discoloration
and may result in a surface haze. Any haze or blush must be removed by water washing before recoating. When using under
fireproofing products, defer to the primer surface preparation requirements in the product data sheet of the fireproofing product.
During high humidity conditions, it is recommended that the application be done while temperatures are increasing.

* These times are based on 50% relative humidity and 1-2 mils (25-50 microns) dry film thickness. If the maximum recoat time is
exceeded the surface must be abraded by sweep blasting or by the application of another coat of Rustbond before applying any
additional coatings.

CLEANUP & SAFETY

Use Thinner #2 or Acetone. In case of spillage, absorb and dispose of in accordance with local
Cleanup
applicable regulations.

Read and follow all caution statements on this product data sheet and on the SDS for this product.
Safety
Employ normal workmanlike safety precautions.

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
Ventilation concentration from reaching the lower explosion limit for the solvents used. User 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.
