Abstract
ABSTRACT MS2A was a reduced ketone resin and a preferred varnish for many painting conservators but ceased production in 2014. To remedy this, a new, more consistent manufacturing process has recently been developed and the next generation of resin designed with replicated chemistry is called MS3. Direct comparison between MS3 and MS2A is limited as no fresh samples of MS2A exist, so work presented here focuses primarily on the performance and characteristics of MS3 compared to literature reports of MS2A, and comparisons to older reference samples of MS2A. Refractive index, gloss, glass transition temperature, and molecular weight are presented. MS3 and comparative low molecular weight varnish resins were artificially aged and examined using FTIR and color measurements. Practical handling and performance were evaluated by varnishing two oil paintings. This study has shown that new MS3 resin demonstrates consistency with older samples of MS2A alongside improvements in keto-reduction, color, flow, and batch to batch consistency.

The American Institute for Conservation is the largest conservation membership organization in the United States, and counts among its more than 3000 members the majority of professional conservators, conservation educators and conservation scientists worldwide. The Journal of the American Institute for Conservation (JAIC, or the Journal) is the primary vehicle for the publication of peer-reviewed technical studies, research papers, treatment case studies and ethics and standards discussions relating to the broad field of conservation and preservation of historic and cultural works. Subscribers to the JAIC include AIC members, both individuals and institutions, as well as major libraries and universities.
