Product Information
ChemLine® 784/32
Description
ChemLine® 784/32 delivers significantly improved product performance and anti-corrosion resistance. ChemLine® 784/32 is
formulated with new patented breakthrough high functionality oxirane polymer.
Designed and engineered with 28 functional groups per molecule, this bridged aromatic backbone structure when polymerized
translates into 784 crosslinks.
ChemLine® 784/32‘s Higher Cross-Link Density Means:
- Higher Chemical Resistance
- Higher Toughness
- Higher Heat Resistance
- Higher Resistance to Abrasion
ChemLine® 784/32 is a high functionality, two component thermoset polymer coating. When cured, ChemLine® 784/32 high
cross-link density is unlike other coatings. ChemLine® 784/32 cross-links predominately through an ether (carbon-oxygen-carbon) linkage. This eliminates high concentrations of hydroxyl groups (found in epoxies) and precludes formation of ester groups (found in vinylesters) which are subject to hydrolysis and acid attack.
ChemLine® 784/32 can be ambient cured over time or low temperature forced air cured for immediate service.
ChemLine® 784/32 Provides Superior Chemical Resistance to:
- 98% Sulfuric Acid
- 37% Hydrochloric Acid
- 50% Sodium Hydroxide
- Most acids, alkalies, and solvents
- Methanol
- Methylene Chloride
- Acetic Acid

Application
Data
Note: The following application data is provided as a general guide only. Detailed instructions are provided
for MarineLine 784 coating systems. Only full detailed application
specifications are to be used during actual application of
any ChemLine® 784/32 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. Use
ChemLine® Primer as first coat.
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, Xylene, Toluene
Limitations
Apply when the air and surface temperatures are above 60°F (15°C). Relative humidity must be kept at 50% 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” by 6‘ whip hose. This coating is a low VOC compliant material. If shop conditions
require a viscosity adjustment, thin with Toluene or Xylene.
Recoat Time (Per Coat)
| Temp. °C (°F) |
Overcoat Minimum |
Overcoat Maximum |
| 60 (16) | 12 Hrs. | 72 Hrs |
| 68 (20) | 8 Hrs. | 72 Hrs |
| 77 (25) | 8 Hrs. | 48 Hrs |
| 86 (30) | 6 Hrs. | 48 Hrs |
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 180°F (82°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.

Form 3 Dimensional Screen-Like Structures when Cured
ChemLine 784/32
- 28 functionality forming 784 crosslinks
- Very small opening between groups
- Majority of crosslinks are through Ether (C-O-C) bonds. Ether bonds are one of the strongest bonds in
chemistry. Ether bonds give flexibility with chemical resistance.
- No ester groups
