Product Description

Lencolo 5024  Yellowing-resistant Photoinitiator
Lencolo 5024 is a photoinitiator of yellowing-resistant UV system, which has strong absorption at a specific wavelength (250 nm-340 nm). It improves film density and enhances adhesion to primers, significantly increasing water resistance, chemical resistance, yellowing resistance, and overall aging stability. It is suitable for a variety of UV varnish systems, UV-white coatings, and UV adhesives.

Performance

Highly suitable as a photoinitiator for a wide range of UV-curable systemsSignificantly improve the yellowing and aging resistance of various UV resins
Reduces initial yellowing immediately after UV curing, improving primer color appearance and color matching
Offers fast curing rate and improves system's stain resistance
Provides excellent surface and depth cure performance
 

Application

Widely used in white UV inks, clear UV varnishes, yellowing-resistant UV varnishes, weather-resistant UV varnishes, and UV adhesive systems.

Usage method

Can be used alone or in combination with other photoinitiators; combination allows adjustment of the balance between surface and depth curing
Recommended addition level: 0.5~5%
Users are advised to determine the optimal addition level through preliminary testing
