By Technology: Environmental Regulations Reshape Adoption

Solvent-borne methods still anchor 55% of 2024 revenue, yet legislation in the EU and California tightens allowable emissions, accelerating migration to greener platforms. UV-cure technology logs the swiftest expansion at 7.01% CAGR, leveraging instant tack and ≤50 g/L VOC. Henkel’s solvent-free UV line attests to industrial appetite for in-line curing that halves floor space. Water-borne chemistries capture production lines that tolerate 1-24 hour cures and value equipment simplicity. Hybrid UV-moisture systems extend these gains to shadowed areas, preventing uncured pockets under tall components.
