Typical properties may vary between production batches. Laboratory test results apply to the stated method and film thickness. Listed protection periods are manufacturer reference values, not a site-specific service-life guarantee. Actual protection depends on preparation, film thickness, exposure, handling and inspection. Theoretical coverage excludes application losses.
Surface Preparation
For best results, the metal surface should be clean, dry and free from rust, oil and mill scale. The substrate temperature should be between 10°C and 35°C when you apply the product.
Application
Supplied ready to use. Do not thin.
Ambient and product temperatures should be between 10°C and 35°C.
Apply by low-pressure air spray or dipping.
Removal
While still wet: Remove with Tectyl® Biocleaner, Tectyl® 150 or low-pressure steam.
After drying and curing: Remove with Tectyl® Biocleaner or Tectyl® 150.
Storage & Shelf Life
Store between 10°C and 35°C.
Do not allow the product to freeze.
Agitate gently before use; viscosity can change during storage.
When stored correctly, the product is best used within 36 months of the production date.
Coating Compatibility
The manufacturer does not recommend applying other coatings over or under Tectyl® 511-M, because this may cause chemical incompatibility and reduce performance. If you need a primer, please consult our technical team first. Where the TDS requires written authorization from CorPro for a primer, obtain that authorization before use; distributor advice does not replace it.
Health, Safety & Handling
Read the current Safety Data Sheet (SDS) and product label for the exact supplied grade and market before use. Follow their requirements for ventilation, personal protective equipment, ignition control, storage, first aid and disposal. Do not discharge residues into drains, soil or water. Request the matching SDS from White House General Trading.
