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

Features and Benefits

• Excellent chemical resistance
• Surface tolerant characteristics for less severe applications
• Self-priming and primer/finish capabilities
• Excellent abrasion resistance and hardness
• VOC compliant to current AIM regulations
• Non-skid service with optional fillers

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
• 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 prior to the application of additional coats
• 890 LT applied below 10°C may temporarily soften as temperatures rise to 16°C. This is a normal condition and will not affect performance

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

• Non-Immersion: NACE No. 3/SSPC-SP6
• Profile: 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 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 SDS for this product and use personal protective equipment as directed
• 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
• 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

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