Description

RaiLine 784 delivers significantly improved product performance and anti-corrosion resistance. RaiLine 784 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.

The original RaiLine, introduced in 1987, delivered 5 functional groups (25 crosslinks), far surpassing epoxies which only have 2 functional groups (4 crosslinks) and phenolics which only have 3 functional groups (9 crosslinks).

RaiLine 784’s Higher Cross-Link Density Means:

  • Higher Chemical Resistance
  • Higher Heat Resistance
  • Higher Toughness
  • Higher Resistance to Abrasion

RaiLine 784 is a high functionality, two component thermoset polymer coating. When cured, RaiLine 784’s high cross-link density is unlike other coatings. RaiLine 784 cross-links predominately through an ether (carbon-oxygen-carbon) linkage. This eliminates high concentrations of hydroxyl groups (found in epoxies and phenolics) which are subject to hydrolysis and attack.

RaiLine 784 is low temperature forced air cured for immediate service.

RaiLine 784 Provides Superior Chemical Resistance to:

  • 98% Sulfuric Acid
  • 37% Hydrochloric Acid
  • 50% Sodium Hydroxide
  • Methanol
  • Methylene Chloride
  • Acetic Acid
  • Most acids, alkalies, and solvents

Product Highlights
Superior Corrosion Resistance, Exceptional Toughness

  • Superior bonding qualities
  • Applied to pitted and/or corroded steel
  • Maximum versatility; product cycling
  • Ambient or low temperature force cure
  • Very low VOC – 108 grams/liter (0.9 lbs. per gallon)
  • Non-permeable for product purity
  • Steam cleanable
  • Repairable
  • Complies with FDA 21 CFR 175.300 for food handling
  • High impact resistance
  • Wear and abrasion resistance

More Chemical Resistance than:

  • Stainless Steel
  • Phenol Epoxies
  • Phenolics
  • Rubber

Increased Return on Investment for:

  • Rail Tanker Cars
  • Rail Hopper Cars
  • ISO Tank Containers
  • Offshore Chemical Tanks
  • Over the Road Tankers


The Technology; Epoxies, Vinylesters and RaiLine 784 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 Phenolics And Epoxies

Phenolic’s and Epoxy’s Open Screen Structure   RaiLine 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.


Problems with Phenolics

  • Requires 3 or more coats
  • Requires 3 or more heat cures at 212°F (100°C)
  • Requires final bake at high temperature — 428°F (220°C)
  • Produces water due to condensation reaction when heat curing
  • Extremely brittle
  • Cannot be repaired
  • Poor resistance to bases and oxidizers

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 RaiLine 784 system.

Surface Preparation
Steel:
Grit blast to SSPC10 (Sa 2.5). 3-4 mil (75-100 micron) blast profile.

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 in 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). The substrate temperature should be at least 5°F (3°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 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.
Stripe coat welds and apply 2 spray coats

Cure Time And Temperature
When application of the complete coating system has been approved, the coating can be cured by:
Forced Hot Air – electrically heated air or propane or natural gas combustion heated air only.

6 hours at minimum 200°F (93°C) – maximum 250°F (122°C). Increase temperature 50°F (10°C) per hour to minimum temperature.

All temperatures are substrate temperatures.
