Description
SETFAST® Solvent Based Acrylic Zone Marking Paint is a conventional dry (non-heat applied) solvent based paint. It has been developed for use over concrete, asphalt, brick and other surfaces and parking lot.
Material Use:
Setfast® Acrylic is a solvent-based, fast-drying zone marking paint designed for use on cured asphalt, concrete, and brick surfaces. It is primarily used for traffic and pavement striping in commercial, municipal, and industrial settings such as parking lots, shopping centers, and roadways. This product is not intended for use as a general floor coating and should not be applied to large pedestrian areas due to potential slipperiness when wet.
System Components:
This is a single-component system requiring no primer or topcoat. It can be used alone or in conjunction with reflective glass beads for enhanced visibility. The paint is available in two standard colors: White (TM5632) and Yellow (TM5645). It may be tinted (white only) with up to 4 oz. of exterior-grade colorant per gallon to achieve custom colors such as Handicap Blue.
Applications:
Setfast® Acrylic is ideal for marking lines and symbols on cured asphalt, concrete, and brick surfaces. It is commonly used by pavement stripers, asphalt seal contractors, and maintenance crews for marking parking stalls, directional arrows, crosswalks, and other traffic control indicators. It is suitable for use with stencils and can be applied using airless or conventional spray equipment designed for striping.
Application Details:
- Surface Preparation: All surfaces must be clean, dry, and sound. Remove oil, dust, grease, and any loose material. New asphalt should be aged before application to prevent bleeding. A test stripe is recommended on fresh asphalt.
- Application Method: Airless spray is preferred, using a tip size of 0.015–0.017 inches at 1500–2000 psi. Conventional spray with a 0.1-inch orifice tip may also be used. Brush and roller application are not recommended.
- Film Thickness: Apply at 15.0 wet mils to achieve 7.3–7.5 dry mils.
- Coverage: Approximately 320 lineal feet of a standard 4-inch stripe per gallon, or 107 sq. ft. per gallon. Theoretical coverage is 786–802 sq. ft. per gallon depending on color.
- Dry Time (at 77°F / 25°C, 50% RH):
- Dry-no-pickup: 10 minutes max
- Dry to touch: 10 minutes max
- Pot Life: Not applicable (single-component, solvent-based).
- Cure Time: Fast-drying; full cure typically achieved within minutes under recommended conditions.
- Temperature & Humidity Limits:
- Application temperature: 40°F (4.5°C) to 110°F (43°C)
- Relative humidity: Maximum 85%
- Surface must be at least 5°F above dew point
- UV Resistance: Not specified; however, as a traffic marking paint, it is expected to have moderate UV resistance suitable for outdoor use.
- VOC Content:
- White: 414 g/L (3.45 lb/gal)
- Yellow: 402 g/L (3.36 lb/gal)
- Not compliant with OTC, CARB, or LEED VOC limits
- Shelf Life: 12 months unopened, stored indoors between 40°F and 90°F (4.5°C to 32°C)
Special Notes:
- This product is not compliant with several regional VOC regulations (e.g., OTC, CARB, LEED), and its use may be restricted in certain areas, especially in Canada during summer months.
- Not intended for use on large pedestrian surfaces due to potential slipperiness when wet.
- Reflective markings can be achieved by applying glass beads while the paint is still wet.
- Excessive reduction or thinning is not recommended and may affect performance.
- Clean equipment with acetone, xylene, toluene, or MEK immediately after use.
- Store in a sealed container to prevent fire hazards from solvent-soaked materials.
- Always test adhesion and compatibility on new or previously coated surfaces before full application.
This product is best suited for professional use in traffic and pavement marking applications where fast dry time and durability are required.
