NANOMYTE® MEND 3000-UVP
- Chemical Family
- Polyurethanes (PU)
NANOMYTE® MEND 3000-UVP is an ambient cure, self-healing coating with UV protective properties. When scratched or damaged, the 2-part coating’s self-healing function is activated upon application of a small amount of heat, such as from hot water or a hair dryer, to restore the surface back to its original appearance

- Features
Crack Resistant, Excellent Gloss Retention, Good Scratch Resistance, Good UV Protection, Outdoor Durability, Self Healing. MEND 3000-UVP is enhanced with NEI's UV-Protect (UVP) technology, which blocks UV radiation and protects coated surfaces from the harmful effects of sun and weather exposure. The addition of UVP helps maintain the unique properties of the coating when subjected to long-term outdoor exposure, while preserving the underlying material's strength, coating adhesion, and appearance.

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.
- 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 (> 1.5 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.; 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® SR-Primer.
- Use instructions
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 damaged part in an oven for 5 minutes at 100°C. Higher temperatures or longer heating times will not typically result in additional self-healing.
- Available Quantities
