Carboline Carboguard 890 is a highly chemical resistant epoxy mastic coating with exceptionally versatile uses in all industrial markets. Self-priming and suitable for application over most existing coatings, and tightly adherent rust. Serves as stand-alone system for a variety of chemical environments and is also designed for various immersion conditions.

An optional micaceous iron oxide additive (MIO Filler) can be purchased separately and may be used per the Product Data Sheet to enhance corrosion protection and film strength for more aggressive service such as severe marine or heavy industrial uses.

Please Note: The colour shades available are an approximation only. Due to the nature of this Carboline product, it is not possible to show an exact shade match, as each batch is made different.

Product Specification

Drying Times

• 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.
• Recoat intervals may vary from those listed above when using under intumescent fireproofing products.
• Contact Rawlins on Tech - 0113 2455450 (option 2) or [email protected] Sales - 0113 2455450 or [email protected] for recommended cure times before applying Carboline intumescent products.
• For application and cure conditions below 35°F, dehumidify before, during, and after application to prevent ice formation on the surface.
• Maximum recoat/topcoat times are 30 days for epoxies and 90 days for polyurethanes at 75°F (24°C). If the maximum recoat times have been exceeded, the surface must be abraded by sweep blasting or sanding prior to the application of additional coats.

Surface Preparation

General

• Surfaces must be clean and dry. Remove all dirt, dust, oil and all other contaminant.

Steel

• Immersion: SSPC-SP10
• Non-immersion: SSPC-SP6
• 1.5-3.0 mils (38-75 microns) SSPC-SP2 or SP3 are suitable cleaning methods for mild environments.

Galvanised Steel

• SSPC-SP 16: for immersion service create 1.5 to 3 mils, (37.5-75 microns), anchor profile.

Concrete or CMU

• Concrete shall be designed, placed, cured, and prepared per NACE No. 6/SSPC-SP 13, latest edition. This includes abrading to remove all laitance, loose concrete, etc. and to create the surface profile required for the coating system to be used. The concrete shall be considered cured sufficiently for coating when it passes the moisture tests.

Drywall and Plaster

• Joint compound and plaster should be fully cured prior to coating application.

Previously Painted Surfaces

• Lightly sand or abrade to roughen surface and de-gloss the surface. Existing paint must attain a minimum 3A rating in accordance with ASTM D3359 “X-Cut” adhesion test.

Stainless Steel

• SSPC-SP 16: for immersion service create 1.5 to 3 mils, (37.5 to 75) microns, anchor profile.

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 thinning and application techniques may be required above or below normal 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 SDS for this product.
• Keep container closed when not in use.
• Employ normal workmanlike safety precautions.

Ventilation

• When used as a tank lining or in enclosed areas, thorough air circulation must be used during and after application until the coating is cured.
• User should test and monitor exposure levels to ensure all personnel are below guidelines.

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