Technical Details & Test Data

Backbone Polymer Selection

CYMEL U-1052-8 resin contains a combination of butoxymethyl and methylol functionalities, making it a very effective crosslinking agent for backbone polymers such as epoxy and alkyd resins that contain hydroxyl functionality. In addition to entering into crosslinking reactions, CYMEL U-1052-8 resin also has a strong tendency toward self-condensation. Therefore, its practical equivalent weight, on a solids basis, is in the range of 200-280. Increasing the level of CYMEL U-1052-8 resin in a coating formulation will generally increase the hardness and chemical resistance of the cured film, although higher levels may also increase brittleness. The optimum level in a particular formulation should always be determined experimentally.

Catalysis

CYMEL U-1052-8 resin usually does not require the addition of and acid catalyst to the formulation in order to obtain effective cure at common baking temperatures. In most instances, the acidity of other formulation components is sufficient to catalyze reaction. If catalyst addition is required, then the use of either CYCAT® 4040 catalyst or CYCAT 296-9 catalyst, at a level of 0.5-1.0% based on total resin solids, is recommended for normal baking schedules (15-20 minutes at 120-150°C).

Stability

FORMULATION STABILITY

The stability of formulated systems containing CYMEL U-1052-8 resin can be enhanced by the addition of alcohols, amines or a combination of these. For acid-cured systems, low molecular weight primary alcohols such as ethanol or nbutanol are most effective. Recommended amines are either triethylamine or dimethyl ethanolamine at a concentration of 0.5-1.0% on total binder solids.

STORAGE STABILITY

CYMEL U-1052-resin has a shelf life of 720 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, possibly making the resin difficult to pump or pour. Product viscosity can be returned to normal by gentle rewarming, however, care should be taken to avoid excessive localized heating which can result in an irreversible increase in viscosity
