Features & Benefits
- Ready-to-Use Product Features
- Features
- Product variations for metal, wood, and plastic substrates
- Can be used as a complete coating solution or as an additive in other coating formulations
- Achieves self-healing of coating surface and subsurface damage
- Customized formulations possible
- Benefits
- Cost Savings - Reduces raw material, labor, and energy cost of repainting or recoating
- Durability - Increases the service life of coatings by preserving esthetic and protective functions
- Environment - Minimizes the environmental costs and societal impact of repainting (e.g., waste disposal and volatile-organic-compound emissions)
- Maintenance - Eliminates the need to frequently repaint or replace damaged coatings
Applications & Uses
- Compatible Substrates & Surfaces
- Cure Method
- Application Instructions
- Combine 1 part (by weight) of Part A with 1 part of Part B (both components are included with purchase)
- Mix thoroughly until homogeneous and apply promptly (preferably within 2 hours)
- Once applied, transfer coated part to preheated oven within 5 minutes, or otherwise apply heat as soon as possible
- Recommended curing schedule: 80°C for 15 minutes, followed by 120°C for 1 hour
- Application Notes
- Self healing is initiated by heating the film to a temperature of 60°C or greater.
- Healing response is faster at temperatures of 70°C and greater.
- Avoid extended exposure to temperatures in excess of 140°C. ▪ Depending on film thickness and curing conditions, hardness may continue to develop over a period of days to weeks.
- For best performance, when applying to UV-sensitive surfaces (e.g., plastics, composites), apply as thick a coating as possible, and/or ensure a minimum dry film thickness of 1.5 mils. Select the appropriate surface preparation protocol (cleaning and/or surface treatment, priming) and test to ensure coating adhesion has been maximized. Some surfaces (e.g., certain paints, plastics, and composites) may require a primer, such as NANOMYTE® SRPrimer.

Technical Details & Test Data
- Customization
- Viscosity may be adjusted by diluting with MEND Reducer; contact NEI if a higher viscosity is desired.
- Tints and pigments are available, contact NEI for further information.
- DTT (dry-to-touch) time may be reduced with the addition of MEND catalyst. This will also reduce pot life.
Packaging & Availability
- Available Quantities
NANOMYTE® MEND 1000-UVP is sold and shipped directly from NEI in liter or gallon quantities (components A & B are included with purchase). Bulk quantities and customized versions of our MEND coatings are also available upon request – contact NEI for details.
Storage & Handling
- Storage and Handling
Precautions for Safe Handling
Appropriate personal protective equipment should be used at all times. Provide good ventilation or extraction. Avoid contact with eyes, skin, and clothing. Avoid prolonged or repeated breathing of vapor. Wash hands thoroughly after handling. Keep away from heat, sparks, flames, and other sources of ignition.
Conditions for Safe Storage
PART A: Avoid contamination with incompatible materials. Keep away from heat, sparks, flames and other sources of ignition. Residual vapors might explode on ignition. Do not apply heat, cut, drill, and grind or weld on or near this container.
PART B: Keep container tightly sealed. Store at room temperature in a dry place. Keep away from sources of ignition. Protect from cold temperatures (< 60°F). Gelation as a result of low temperature exposure may be reversed by warming to ~100°F for several hours. Purge container with dry, inert gas after use.
NOTE – Components should be stored separately until ready to use. Once mixed, coating solution should be used within the time allotted (see pot life).
