PROTECTIVE LINING FOR ABRASION RESISTANT SERVICE

Description

Siloxirane® 2432 is an abrasion resistant two component ambient or low temperature force cured polymer lining system. Siloxirane 2432 is a tough, flexible lining designed to handle the abrasiveness of coal, ore, plastic pellets, ice flows and other media.

Siloxirane 2432 has excellent chemical resistance capable of withstanding the corrosive attack
that normally comes with media handled.

Application Highlights

• Can be applied to pitted corroded and/or steel surfaces — surface tolerant
• Very high abrasion resistance
• High build
• Ambient cure
• Low VOC - 102 grams/L (0.85 lbs. per gallon)
• Excellent adhesion
• Flexible to take vibration and twisting
• Easily patched by maintenance personnel
• Steam cleanable
• Complies with FDA 21 CFR 175.300
• Resists Hydroblasting

Chemical Resistance

Sulfuric acid to 98%, most solvents including methylene chloride, MEK, methanol, gasohol, distilled water, inorganic acids, dilute organic acids and alkalis. Ideal for corrosive vapor environments.

Industry Applications:

• Hopper cars
• Slurry pipe
• Legs of oil platforms
• Pumps
• Underwater areas of ships for resisting ice abrasion
• Small boats and yachts to resist sand abrasion

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 Siloxirane 2432 system.

Surface Preparation
Steel:
Grit blast to SSPC5 (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, 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 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.

Recoat Time (Per Coat)

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.

Coverage
Practical at recommended film thickness:
2432 — (Avg. 22 mils DFT) 70 sq. ft./gal.
