Technical Details & Test Data
- 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 is compatible with a wide range of backbone polymers providing films with superior adhesion and resistance properties. The effective equivalent weight of CYMEL 1141 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.
- Catalysis
Because of its high extent of alkylation, CYMEL 1156 resin responds best to sulfonic acid catalysts, like CYCAT® 4040 catalyst or CYCAT 600 catalyst. Generally, 0.5 to 1.0% of CYCAT 4040 catalyst on total resin solids of the formulation is sufficient to provide good cure at normal baking schedules (15-20 minutes at 120-150°C) in solvent-borne systems. Water-borne systems generally require temperatures of 150°C or higher to effect cure. Higher concentrations of catalyst might be necessary if there are basic pigments or additives present in the formulation.
- Stability
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.
STORAGE STABILITY
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.
