Application & Curing Guidelines
1.Light & Moisture Sensitive: Keep the container tightly closed and handle the product in a dry environment. Strictly minimize exposure to sunlight, UV light, and strong indoor lighting during storage and use.
2.Surface Preparation: Clean the substrate thoroughly to remove dust, oil/grease, fingerprints, and other contaminants to achieve optimal adhesion.
3.Application Methods: Compatible with manual brushing, automated selective spray coating, and dipping. If the material is agitated, allow it to stand until air bubbles dissipate before use.
4.Curing Process:
UV Cure: Speed depends on UV intensity, wavelength, film thickness, and distance. Typically, coating becomes tack-free immediately after sufficient UV exposure.
Moisture Cure (Shadowed Areas): For areas UV light cannot reach, moisture cure will proceed automatically. Room-temperature cure takes ~3 days for basic cure, and 7–14 days to reach ultimate properties.
5.Cleanup: Uncured material can be removed using suitable organic solvents (e.g., IPA, MEK).
Safety, Packaging & Storage
Packaging: Available in 1kg opaque containers.
Safety Precautions: Avoid skin contact with the uncured material. In case of eye contact, rinse immediately with plenty of water and seek medical attention.
Storage Conditions: Store tightly sealed in a cool, dry, and dark place. Maintain storage temperatures strictly between 8°C and 25°C.
Shelf Life: 6 months in original, unopened packaging.
