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.

Siloxirane 2032 introduced in 1992, delivered 5 functional groups (25 crosslinks), far surpassing epoxies and vinylesters which only have 2 functional groups (4 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 solvent
  • Methanol
  • Methylene Chloride
  • Acetic Acid

The Technology; Epoxies, Vinylesters and ChemLine 784/32 Form 3 Dimensional Screen-Like Structures when Cured

The Greater the Distance Between the Crosslinks, the Greater the Permeation Causing Chemical Attack and Absorption

Problems with Epoxies and Vinylesters

Vinylester’s and Epoxy’s Open Screen Structure   ChemLine 784’s Closed Screen Structure
 
AGGRESSIVE CHEMICAL MOLECULES PENETRATE INTO AND THROUGH THE POLYMER GROUPS ATTACKING BOTH THE INNER POLYMER STRUCTURE AND THE SUBSTRATE.   AGGRESSIVE CHEMICAL MOLECULES CANNOT PENETRATE THE HIGH DENSITY SURFACE. INNER POLYMER STRUCTURE AND SUBSTRATE PROTECTED FROM CHEMICAL ATTACK.
     

ChemLine 784/32

  • 28 functionality
  • 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

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 784/32 systems.

Surface Preparation
Steel:
Grit blast to SSPC10 (Sa 2.5). 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, Xylene, Toluene

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 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 60:1 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 minimum180°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.

Worldwide Independent Test Laboratories Certify APC’s Coatings’ (MarineLine 784, ChemLine 784, RaiLine 784) Corrosion Resistance and Non-Absorption Qualities

A History of Performance
For more than two decades Siloxirane (now ChemLine) has withstood the tremendous stresses and extremes of chemical attack and abrasive wear. Siloxirane coatings and linings have been proven worldwide under the most arduous operating conditions, from resisting the most aggressive chemicals to handling hot pipelines in subfreezing temperatures, Siloxirane coatings have a history of success. Based on this experience, the development of ChemLine 784/32 represents a Quantum Leap in chemical resistant polymer coatings.
