Radiation-cured coatings are widely used in the automotive, electronics, packaging and other fields due to their high efficiency and environmental protection. Their core advantage is that they can instantly trigger the cross-linking reaction of the coating through ultraviolet (UV) or electron beam (EB), thus achieving a green process of "zero solvent evaporation". Additives, as key components of the formula, directly determine the mechanical properties, surface gloss and durability of the coating.
Functional classification and technological breakthroughs of additives
Matte control additives
Matte additives represented by Shenzhen Youyang HM-103 can precisely control the gloss of the coating (60° angle ≤15, 85° angle ≤50) by introducing fatty acid metal salts (such as calcium stearate) and acrylate compounds. This type of ingredient is particularly suitable for wood and plastic substrates, meeting the needs of high-end furniture and electronic products for low-reflective surfaces.
Nano-enhanced additives
Nano-silica dispersions and micronized waxes can significantly improve the scratch resistance of the coating. For example, the cross-linked nano-additives developed by BYK USA can increase the wear resistance of the coating by more than 30% without affecting transparency.
Environmentally friendly reactive diluents
Under the trend of solvent-free formulations, low molecular weight acrylate monomers (such as HDI isocyanurate) are used as diluents to reduce the viscosity of the system and participate in the cross-linking reaction to reduce VOC emissions.
HM-103: Innovative formula and market competitiveness
The HM-103 additive launched by Shenzhen Youyang is specially designed for matte coatings. Its technical highlights include:
Multi-component synergistic effect: combining polyester acrylate with zinc/calcium metal salts to achieve gloss stability and fast curing (UV dose <0.15 J/cm²).
Wide compatibility: suitable for UV inks, overprint paints and protective coatings for electronic devices, suitable for a variety of substrates such as plastics and metals.
Environmental certification: in compliance with EU REACH standards, solvent residue <0.5%, helping companies pass green supply chain audits.
Industry Trends and Future Outlook
With the rise of bio-based materials (such as palm oil derivatives), radiation-curing additives are transitioning towards renewable sources. At the same time, intelligent production is driving the demand for "dual-curing system" (UV+thermal curing) additives to meet the coating challenges of complex three-dimensional structures.
The technological iteration of radiation-curing coating additives is driving coating performance towards higher durability and lower environmental load. Choosing innovative products such as HM-103 can help companies reduce costs and increase efficiency and meet diversified market needs.
