Description
TECTYL® 1431 is a premium high solids, solvent-based corrosion preventive coating manufactured by Daubert Chemical Company. This environmentally conscious formula features a low VOC content (2.8 lbs/gallon) and is completely free of Hazardous Air Pollutants (HAPs), while providing an effective barrier against corrosive environments for both ferrous and non-ferrous fabrications and industrial components. The rapid-drying black coating forms a hard, flexible, and durable protective film that delivers exceptional corrosion resistance while maintaining excellent mechanical properties, making it ideal for trailer sub-frames, intermodal chassis, rail cars, and various road, farm, and construction equipment.

Application Guidelines
TECTYL® 1431 is formulated to be used as supplied without thinning. Ensure uniform consistency prior to use, though continued stirring is generally not required.
Surface Preparation:
- For maximum performance, metal surfaces must be clean, dry, and free of rust, oil, and mill scale
- Recommended substrate temperature during application: 50-95°F (10-35°C)
Application Methods:
- Can be applied by airless spray, conventional spray, or brush
Equipment Recommendations:
- Pump Ratios:
- Low Ratio: 23-30:1, maximum hose length of 150 ft
- High Ratio: >40:1, maximum hose length of 250 ft
- Spray Gun Nozzles:
- Tungsten carbide tips with .015″ to .021″ orifice size
- Fluid Hoses:
- Minimum diameter of 3/8 inch, less than 50 ft of material hose for optimal flow
- Fluid Pressure:
- 1800-2400 psi is required for efficient application
Important Notes:
- If product thickens due to cold storage or loss of solvent, contact Daubert Chemical Company
- DO NOT THIN the product as incorrect thinning will affect film build, dry time, and performance
- The dry film is not normally intended for removal but can be stenciled over after the film is cured
- Xylene, Acetone, or Ketone solvents will remove fresh residue accumulated on application equipment
- If removability is a factor, contact Daubert Chemical Company and samples should be evaluated prior to application
Storage and Handling
- Store at temperatures between 50-95°F (10-35°C)
- Mild agitation is recommended prior to use
- Adequate ventilation is required for cure and to ensure against formation of a combustible liquid
- The partially cured film should not be exposed to ignition sources such as flares, flames, sparks, excessive heat, or torches
- The addition of any product over or under this coating is not recommended due to potential chemical incompatibility
- Refer to Daubert’s Material Safety Data Sheet for complete health and safety instructions
