Carboline Carbocrylic 3359 DTM is a single-component durable, high performance acrylic coating for use where excellent weathering properties and chemical resistance are required. Use as a direct-to-metal acrylic coating for tank exteriors, piping, and structural steel, as well as other exterior and interior uses. May also be used as a finish coat over recommended primers..

Features & Benefits

• Smooth, attractive, high build finish
• Excellent weatherability, gloss and colour retention
• Low odor
• Excellent corrosion protection
• Meets most VOC (Volatile Organic Content) regulations
• Excellent resistance to flash rusting
• Outstanding application characteristics
• Dry-fall* properties

*Overspray can be wiped or washed from most surfaces depending on temperatures and humidity. The longer the overspray dwells on the surface and the hotter the surface, the more difficult to remove. A 20-foot (distance) test is recommended.

Product Specification

Drying Times

• These times are based on 50% relative humidity and 3-4 mil (75-100 microns) dry film thickness.
• The acrylic film forming process may require several weeks at 75°F (24°C) with proper ventilation to develop adhesion and water resistance.
• High humidity, high film thickness, insufficient ventilation or cooler temperatures will lenghten dry to handle/topcoat times due to slower water evaporation rate.
• Waterborne acrylics are sensitive to moisture during early cure and are susceptible to handling damage
• 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.

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

• SSPC-SP6 with a 1.0-2.0 mil (25-50 micron) surface profile for maximum protection. SSPC-SP2 or SP3 as minimum requirement.
• Prime with specific Carboline primers as recommended by Rawlins on Tech - 0113 2455450 (option 2) or [email protected] Sales - 0113 2455450 or [email protected]
• When using under fireproofing products, defer to the primer surface preparation requirements in the product data sheet of the fireproofing product.

Galvanised Steel

• SSPC-SP1. Prime with Sanitile® 120 or others as recommended by Rawlins.
• When using under fireproofing products, defer to the primer surface preparation requirements in the product data sheet of the fireproofing product.

Concrete

• Must be cured 28 days at 75°F (24°C) and 50% relative humidity or equivalent. Laitance, form oils, curing agents and hardeners must be removed by suitable method before coating application.
• Prime with Sanitile 120

CMU

• Mortar joints should be thoroughly cured for a minimum of 15 days at 75°F (24°C) and 50% relative humidity or equivalent.
• Prime with a latex block filler

Drywall & Plaster

• Joint compound and plaster should be fully cured prior to coating application. Prime with Sanitile 120.

Previously Painted Surfaces

• Lightly sand or abrade to roughen surface and degloss the surface. Existing paint must attain a minimum 3A rating in accordance with ASTM D3359 “X-Scribe” adhesion test.
• Contact Rawlins for information on suitable primers.

Wood

• Lightly sand with fine sandpaper and remove dust. Prime with Sanitile 120.

Application Methods

Application Conditions

• Do not apply when the surface temperature is less than 5°F (3°C) above the dew point.
• Do not apply if temperatures are expected to drop below 50°F (10°C) within 24 hours of application
• Special application techniques may be required above or below normal application conditions.

Health & Safety

Clean Up

• Use clean potable water followed by butyl glycol or other suitable solvent to dry equipment. In case of spillage, absorb and dispose of in accordance with local applicable regulations

Safety
