Product Description

Product Description

7224-1 is a high-performance aliphatic polyurethane acrylate (PUA) photocuring resin, meticulously designed to meet the demands of premium UV applications. It combines multiple advantages including low shrinkage, excellent flexibility, fast curing, superior film formation, outstanding yellowing resistance, and low exotherm during curing, making it an ideal choice for various UV formulations.

During photocuring, the 7224-1 resin exhibits extremely low volume shrinkage, effectively reducing internal stress caused by shrinkage. This significantly enhances the flexibility of the coating or adhesive layer and its adhesion to substrates. This makes it particularly outstanding in applications requiring good bending performance and impact resistance, such as flexible UV leather, UV plastics, and UV nail gels.

This resin features a rapid curing speed, which can greatly improve production efficiency and shorten processing times. Simultaneously, its low heat generation during curing is especially suitable for heat-sensitive substrates like thin wood veneers, certain plastics, and nails, preventing substrate deformation or damage due to overheating.

After curing, the 7224-1 resin forms a smooth, high-gloss film with excellent physical properties. As an aliphatic polyurethane acrylate, it possesses outstanding UV resistance, ensuring long-term non-yellowing and maintaining the aesthetic appeal of the product. This is particularly important for light-colored or transparent UV nail gels, UV wood coatings, and UV plastic finishes.

Thanks to its balanced performance, the 7224-1 resin is widely used in various UV systems, including UV nail gel, UV leather, UV wood coatings, UV plastics, and UV inks, making it an ideal choice for enhancing UV product performance.

Frequently Asked Questions

What type of chemical structure does the 7224-1 resin have?

7224-1 is a 2-functional aliphatic polyurethane acrylate (PUA) oligomer, engineered for high yellowing resistance and exceptional flexibility.

Why is this PUA resin ideal for heat-sensitive substrates?

During the UV curing process, 7224-1 exhibits low exotherm (heat generation), preventing deformation or heat damage in thin wood veneers, specific plastics, and nail beds.

How does low shrinkage affect the coating properties?

Low volume shrinkage minimizes internal stress during UV curing. This results in superior flexibility, improved adhesion to challenging substrates, and enhanced impact resistance.

What are the storage requirements to prevent premature polymerization?

Keep the resin in dark, opaque containers with at least 15% air headroom inside. Store below 35°C in a dry environment and avoid any direct contact with sunlight.

Can 7224-1 be used for transparent finishes without yellowing?

Yes, because of its aliphatic chemical nature, this resin offers excellent resistance to UV radiation, securing long-lasting optical clarity without yellowing over time.
