Application Guidelines
TECTYL® 4033 is formulated to be used as supplied without thinning. This water-based coating requires specific handling and application considerations.
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
- For optimal results, ensure ambient and product temperature is between 50-95°F (10-35°C) at time of application
Equipment Recommendations:
- Airless pumps with ratios of 10:1 or greater
- Deliver 80-120 psi to a 0.017-0.025 reverse-a-clean tip for efficient application
Important Notes:
- If product thickens due to cold storage or loss of water during use, contact Daubert Chemical Company
- DO NOT THIN the product as incorrect thinning will affect film build, dry time, and performance
- Water-based formula should not be exposed to freezing conditions
- The addition of any product over or under this coating is not recommended due to potential chemical incompatibility
Storage and Handling
- Store at temperatures between 50-95°F (10-35°C)
- Mild agitation is recommended prior to use
- Protect from freezing temperatures
- Adequate ventilation is required for cure
- The partially cured film should not be exposed to ignition sources such as flares, flames, sparks, excessive heat, or torches
- Can be removed with TECTYL® HPS solventborne thinner, vapor degreasing, hot alkaline wash, or low-pressure steam
- Can be removed from fabrics by normal dry cleaning procedures
- Avoid using chlorinated or highly aromatic solvents when removing from painted surfaces, as these solvents may adversely affect paint
- Refer to Daubert’s Material Safety Data Sheet for complete health and safety instructions
