Carboline Carboguard 890 GF is a glass reinforced chemically resistant epoxy coating with wide versatility in all industrial markets. This self-priming coating uses the glass reinforcement to improve internal film strength, hardness, impact, and abrasion resistance. It is often used in severe service (above or below the waterline) in marine applications where these resistance qualities are desired.

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 24°C. If the maximum recoat times have been exceeded, the surface must be abraded by sweep blasting or sanding to create mechanical anchor profile prior to the application of additional coats.

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

• Immersion: NACE No. 2/SSPC-SP10
• Profile: 3.0-4.0 mils (75-100 microns)
• Non-Immersion: NACE No. 3/SSPC-SP6
• Profile: 2.0-3.0 mils (50-75 microns)
• SSPC-SP2, SP3 or SP15 are suitable cleaning methods for mild (non-immersion) environments and touch up.

Galvanised Steel

• Abrasive blast as per SSPC-SP16 to achieve a minimum 50-75 microns profile.

Concrete or CMU

• NACE No. 6/SSPC-SP13 and create surface profile of ICRI CSP 3 to 4.

Previously Painted Surfaces

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

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.
• 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 as a tank lining or 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 supplied air respirator.

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