- 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
- Markets
- Application Instructions
- Combine 4 parts (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, dry-to-touch conditions can be achieved within 30 minutes (1 mil @ 25°C)
- Recommended ambient cure time of 60 hours for general use; up to 60 days for full properties
- Accelerated cure can be achieved on dry-to-touch samples by baking for 30 minutes at 100°C
- Application Notes
- A slight, uniform haze is normal for Part A liquid. It will clear when mixed with Part B.
- Dry-to-touch for thick films (> 1 mil) may be longer than 30 minutes.
- 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.
- Deep scratches may not be completely healed or may require higher temperatures to heal.
- Avoid extended exposure to temperatures in excess of 140°C.
- Depending on film thickness and curing conditions, hardness and solvent resistance may continue to develop over a period of weeks to months.
- Instruction For Use
- Use care when first damaging the surface for demonstration purposes. Sharp instruments may cause irreversible damage. Gouges or deep cuts may not fully heal.
- Self-healing begins at 60°C. To demonstrate rapid self-healing properties, the film must reach a uniform temperature of 80°C or greater for at least 5 seconds. Hot water (> 80°C) is very efficient for demonstration purposes. Otherwise, use of a heat gun is recommended.
- For testing purposes, complete healing can be ensured by placing the part in an oven for 5 minutes at 100°C.
- Oven-healing for durations beyond 5 minutes, or at temperatures above 110°C, will not typically result in additional self-healing.

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 3000 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

Precautions for Safe Handling
Contains a potential sensitizer! Appropriate personal protective equipment should be used at all times. Provide good ventilation or extraction. Avoid contact with eyes, skin, and clothing. Avoid inhalation of vapor or mist. Keep away from heat, sparks, flames and other sources of ignition.
Conditions for Safe Storage
PART A: Ambient temperature storage is preferred; avoid temperature extremes. 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. Precipitation from low temperature exposure may be reversed by warming.
PART B: Keep container tightly sealed. Store at room temperature in a dry place. Keep away from sources of ignition. Protect from cold temperatures. Gelation may occur as a result of reaction with moisture. 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).
