    Description

    MS3 is a specialty resin uniquely developed for conservation and cultural heritage applications.  Employing sustainable state of the art production technology, MS3 has been engineered to carefully replicate the chemistry of previously available MS2A Resin.

    For decades, low molecular weight synthetic resins have been used to replace natural resin painting varnishes such as damar and mastic, which discolor and cross-link due to oxidation.  MS2A was originally developed in the 1950's and supplies have been depleted since production ceased in 2014.  It is preferred by many conservation professionals because of its handling, appearance, longevity, and reversibility.

    Advances in production have created a product with an improved color, chemical stability, and consistency between batches.  The resin, now named MS3, is a superior, high-performing successor to the original resin and is now readily available.
