Carboline Carboguard 890 LT 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 to rust. Excellent for use as a primer or intermediate coat where low temperature cure is needed. Can be used in a variety of chemical environments. May be used as a self-priming or finish coat on exterior exposure if discolouration can be tolerated.

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 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

Steel

• Minimum SSPC-SP6 for most applications
• Profile: 1.5-3.0 mils (38-75 microns), SSPC-SP2 or SP3 are suitable cleaning methods for mild environments.

Galvanised Steel

• Prime with specific Carboline primers as recommended by Rawlins on Tech - 0113 2455450 (option 2) or [email protected] Sales - 0113 2455450 or [email protected]

Concrete or CMU

• The concrete must be cured for 28 days (at 75°F/50% R.H.) or until the concrete reaches its designated compressive strength.
• Prepare and clean the surface in accordance with SSPC-SP13/NACE No. 6 guidelines.
• Test for moisture by conducting a plastic sheet testing in accordance with ASTM D4263

Dry Wall 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 3B rating in accordance with ASTM D3359 “X-Scribe” adhesion test.

Application Methods

Application Conditions

• This product simply requires the substrate temperature to be above the dew point.

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.
• 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.
• 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.
