Product Information
ChemLine® 784/32
Description
ChemLine® 2400/32 is an abrasion resistant two component ambient or low temperature force cured polymer lining system. ChemLine® 2400/32 is a tough, flexible lining designed to handle the abrasiveness of coal, ore, plastic pellets, ice flows and other media.
ChemLine® 2400/32 has excellent chemical resistance capable of withstanding the corrosive attack that normally comes with
media handled.

Application Data
Note: The following application data is provided as a general guide only. Only full detailed application specifications are to be used during actual application of the ChemLine® 2400/32 system.
Surface Preparation
Steel:
Abrasive blast to SSPC-SP10 (NACE #2, Sa 2.5) near white metal finish. 3-4 mil (75-100 micron) blast profile.
Concrete:
Abrasive blasting is the preferred method to ensure superior bonding. However, the concrete can be prepared by slurry blasting, hydroblasting, or scarifying. The profile of the prepared concrete should be similar to that of coarse sandpaper.
Mixing Instructions
Material is supplied in two containers as a unit. Always mix a complete unit in the proportions supplied.
(1) Thoroughly mix the contents of Part A with a power agitator until uniform consistency and color is obtained. Be sure that any solids that may have settled through storage have been put back into suspension.
(2) Slowly combine the contents of the activator with the previously mixed Part A.
(3) Thoroughly mix the two parts until a uniform consistency and color is obtained.
Clean Up Solvent
Acetone, Toluene, Xylene
Limitations
Apply when the air and surface temperatures are above 60°F (15°C). Relative humidity must be kept at 60% or lower. The substrate temperature should be at least 5°F (-15°C) above the dew point and rising. For optimum application properties bring material to 68-77°F (20-25°C) prior to mixing and application. Increased temperatures will result in shorter pot life.
Application
Airless spray equipment with minimum 45:1 pump ratio @ 80-100 lbs. To achieve 2500-3000 p.s.i. tip pressure; Reverse-A-Clean tip .019 to .023, with 3/8” fluid hose, and 1/4” whip hose. This coating is a low VOC compliant material. If shop conditions require a viscosity adjustment, thin with Toluene or Xylene.

Cure Time And Temperature
When application of the complete coating system has been approved, the coating can be cured by either:
A) Ambient Cure @ 75°F (24°C) {Concrete Application}
To walk on - 24 hours
To drive on - 3 days
For Full Chemical Resistance contact the APC technical department for required time and temperatures for specific chemicals.
Note: Some chemicals will discolor surface.B) Forced Hot Air {Tank Applications} - electrically heated air or propane or natural gas combustion heated air only. 6 hours at minimum 200°F (93°C).
All temperatures are substrate temperatures.
Contact APC for detailed heat cure requirements.
Handling Precautions
Solvents and chemicals are contained in this product. Consult the Material Safety Data Sheet for details. Adequate safety and health precautions should be taken during handling, application and drying of this product. The material should be applied under local, state, federal regulations and in accordance with OSHA and ANSI bulletins on safety requirements.
