- Catalysis
CYMEL 211 resin responds to catalysis by weak, low dissociation acids. For acceptable cure response at baking temperatures above 125℃, in most instances the carboxyl functionality of the other resins in a formulation would be an adequate catalyst. If catalyst addition is found to be necessary, then virtually any soluble acid would be effective. Normally, phosphate esters, or sulfonic acids are recommended. The acid concentration would have to be determined for each system. Cure response at lower baking temperatures is possible, but higher catalyst concentrations are necessary.
- Stability
FORMULATION STABILITY; Formulated systems containing CYMEL 211 resin have to be stabilized with primary alcohols, amines or with a combination of these. Low molecular weight primary alcohols such as ethanol and n-butanol are most effective. Recommended amines are TEA, DMEA or 2-AMP at a concentration of 0.5-1.0% on total binder solids. Acid curing systems are usually stabilized only by addition of adequate amounts of primary alcohols.; STORAGE STABILITY; CYMEL 211 resin has a shelf life of 540 days from the date of manufacture when stored at temperatures between 5°C and 25°C packed in unopened original container. CYMEL 211 resin must be kept indoors and avoided the direct sunlight exposure. 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.
