Title:
ACTINIC RAY PRE-ILLUMINATION CURING METHOD FOR ACTINIC RAY CURABLE ANAEROBIC ADHESIVES
Document Type and Number:
WIPO Patent Application WO/2021/051301
Kind Code:
A1
Abstract:
A curing method for an actinic ray curable anaerobic adhesive comprises the steps of: a) providing a first substrate; b) applying an actinic ray curable anaerobic adhesive to a surface of the first substrate; c) radiating the anaerobic adhesive with an actinic ray for a pre-illumination time which is from 20 to 60% of the actinic ray curing time of the actinic ray curable anaerobic adhesive measured under the same actinic ray and intensity; d) laying a second substrate over the first substrate so that the actinic ray curable anaerobic adhesive is in between the first substrate and the second substrate, and the actinic ray curable anaerobic adhesive is cured under anaerobic condition. The actinic ray curable anaerobic adhesive cured by the curing method has shortened fixture time under anaerobic condition.
