Technical Details & Test Data

Backbone Polymer Selection

CYMEL MB-98 resin is a very effective crosslinking agent for backbone polymer resins containing hydroxyl functional groups, such as alkyd, polyester or acrylic resins. The optimum level of CYMEL MB-98 resin in an acid curing wood coating formulation should be in the range of 25-35% on total resin solids if used as the sole crosslinker. Loadings of 5-10% on total resin solids is recommended when used in combination with a urea resin.

Catalysis

CYMEL MB-98 resin responds best to sulfonic acid catalysts, like CYCAT® 4040 catalyst. Generally, 6-10% CYCAT 4040 catalyst on total resin solids of the formulation is sufficient to obtain fast drying behavior at room temperaturecc

Stability

STORAGE STABILITY

CYMEL MB-98 resin has a shelf life of 1440 days from date of manufacture when stored at temperatures below 32°C. Although low temperatures are not detrimental to stability, the viscosity of the product will increase making the resin more difficult to pump or pour. Product viscosity can be returned to normal by gentle warming, however, care should be taken to avoid excessive localized heating as this can cause an irreversible increase in viscosity.

Pot Life

To extend catalyzed pot life of the formulation, addition of primary alcohols, such as n-butanol and ethanol, is required at concentrations of 10-25% on total resin solids. Faster evaporating alcohols will improve speed of dry.
