Hardener RG 103 is an aqueous solution of sulphonic acids. Its trade form is a yellowish-dark brown clear liquid. RG 103 hardener is used for curing urea-furfuryl-formaldehyde resins, particularly ones containing furfuryl alcohol, e.g. 60% and cold cured phenolic resins. Given its slow effect it is recommended for summer seasons.
