- Formulation Stability
- The stability of formulated systems containing CYMEL® 243-3 Resin can be enhanced by the addition of alcohols, amines or a combination of these.
- Low molecular weight primary alcohols such as ethanol or n-butanol are generally most effective.
Properties
Technical Details & Test Data
- Catalysis Information
- CYMEL® 243-3 Resin usually does not require the addition of an 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, use of a weak inorganic acid catalyst such as CYMEL® 296-6 catalyst at a level of 1.0-2.0% based on weight of total binder solids is recommended for baking schedules of 125 150°C for 15-20 minutes.
- Backbone Polymer Selection
- CYMEL® 243-3 Resin contains a combination of butoxymethyl and methylol functionalities, making it a very effective crosslinking agent for backbone polymers such as alkyd and polyester resins containing hydroxyl, carboxyl or amide functionality.
- In addition to entering into crosslinking reactions, CYMEL® 243-3 Resin also has a strong tendency toward self-condensation.
- Therefore, its practical equivalent weight, on a solids basis, is in the range of 220-280.
- Typical use levels of CYMEL® 243-3 Resin are between 15% and 35% based on total resin solids.
- When used as a leveling agent, CYMEL® 243-3 Resin is typically added at between 2% and 5% based on total resin solids.
- Note that the appropriate use level in a particular formulation should always be determined experimentally.
Packaging & Availability
Storage & Handling
- Storage Conditions
- CYMEL® 243-3 Resin has a shelf life of 1440 days from date of manufacture when stored at temperatures between 5°C and 32°C.
- Although lower 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 re-warming, however, care should be taken to avoid excessive localized heating which can result in an irreversible increase in viscosity.
