CYMEL® 1141

CYMEL® 1141 Resin is a highly methylated/iso-butylated, carboxy-modified melamine crosslinker supplied in iso-butanol. CYMEL® 1141 Resin is especially designed for electro-deposition primer formulations requiring excellent corrosion and resistance properties. CYMEL® 1141 Resin contains chelating groups which can form colored compounds with heavy metal ions such as iron and zinc. For that reason it is recommended to use CYMEL® 1141 Resin only in dark single coat applications or primers and not in pastel colors.

Formulation Stability
  • The stability of formulated systems containing CYMEL® 1141 Resin can be enhanced by the addition of alcohols, amines or a combination of these.
  • Low molecular weight primary alcohols such as methanol and n-butanol are most effective.
  • Recommended amines are dimethylethanolamine (DMEA), triethylamine (TEA), or 2-amino-2-methyl-1-propanol (AMP) at a concentration of 0.5-1.0% on total binder solids.
  • Package stability can also be enhanced by the use of a blocked acid catalyst such as CYCAT 4045 catalyst.
  • For waterborne systems a pH of 7.5-8.5 should be maintained for adequate stability.

Properties

Technical Details & Test Data

Catalysis Information
  • CYMEL® 1141 Resin will respond best to sulfonic acid catalysts, like CYCAT® 4040 catalyst or the amine-blocked version, CYCAT 4045 catalyst. Generally, 0.5 to 1.0% catalyst solution on total binder solids of the formulation is sufficient to provide good cure at baking schedules of 20 minutes at 120°C to 160°C.
  • Higher concentrations might be necessary if there are basic pigments or additives present in the formulation.
  • Waterborne systems generally require temperatures of 150°C and higher to effect cure.
Backbone Polymer Selection
  • CYMEL® 1141 Resin contains mainly methoxymethyl and butoxymethyl functionalities making it a very effective crosslinker for backbone polymer resins containing hydroxyl, amide, or carboxyl functional groups, such as found on alkyd, polyester or acrylic resins.
  • CYMEL® 1141 Resin is compatible with a wide range of backbone polymers providing films with superior adhesion and resistance properties.
  • The effective equivalent weight of CYMEL® 1141 Resin typically ranges from 150-250 g/eq, however, its optimum loading should be determined experimentally for each formulation with consideration of the performance properties to be optimized.

Storage & Handling

Storage Conditions
  • CYMEL® 1141 Resin has a shelf life of 1080 days from the date of manufacture when stored at temperatures below 32°C.
  • Although lower temperatures are not detrimental to stability, its viscosity will increase, possibly making the resin difficult to pump or pour.
  • The viscosity will reduce again on warming, but care should be taken to avoid excessive local heat, as this can cause an irreversible increase in viscosity.
