CYMEL® MI-97-IX

CYMEL® MI-97-IX Resin is a partially iso-butylated melamine crosslinker supplied in a mixture of iso-butanol and xylene. Its fast drying behavior provides films with good early block resistance for stacking of parts and makes CYMEL® MI-97-IX Resin suitable for fast low temperature curing systems, like wood and paper coatings, providing very good film hardness, adhesion and appearance.

Pot Life Data
  • 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.
Catalysis Information
  • CYMEL® MI-97-IX Resin responds best to sulfonic acid catalysts, such as CYCAT® 4040 catalyst.
  • For acid curing wood coating formulations, generally 6 to 10% CYCAT 4040 catalyst on total binder of the formulation is sufficient to obtain fast drying behavior at room temperature.
Backbone Polymer Selection
  • CYMEL® MI-97-IX Resin contains a combination of butoxymethyl, methylol and imino functionalities, making it a very effective crosslinker for backbone polymer resins containing hydroxyl functional groups, such as alkyd, polyester or acrylic resins.
  • CYMEL® MI-97-IX Resin is very reactive and has a high tendency to self condense at rather low baking temperatures, providing films with very good hardness, gloss, and resistance properties.
  • Although the optimum level of CYMEL® MI-97-IX Resin should be determined experimentally, ratios of 25 to 35% based on resin solids are typically most effective.

Storage & Handling

Storage Conditions
  • CYMEL® MI-97-IX Resin has a shelf life of 4 years from date of manufacture when stored at temperatures between 5°C and 30°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 re-warming, however, care should be taken to avoid excessive localized heating as this can cause an irreversible increase in viscosity.
