- Formulation Information
- The stability of solvent-borne systems containing CYMEL® 250 Resin can be enhanced by the addition of primary alcohols, amines, or 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.

- Soluble In
- Catalysis Information
- CYMEL® 250 Resin responds to catalysis by weak acids.
- At baking temperatures above 120°C, the carboxyl functionality of the other resins in a formulation would be an adequate catalyst.
- If catalyst is necessary, any soluble acid would be effective.
- Normally, phosphate esters such as CYCAT 296-9 are recommended.
- The acid concentration would have been determined for each system.
- Backbone Polymer Selection
- CYMEL® 250 Resin resin is an efficient cross-linking agent for hydroxyl, amide, carboxyl, functional polymers or resins.
- Similar to other melamine resins with reactive functions, it is not only crosslinks with the above functionalities, but also self- condenses readily.
Regulatory & Compliance

Storage & Handling
- Storage Conditions
- CYMEL® 250 Resin has a shelf life of 1 year from the date of manufacture when stored at temperatures between 5°C and 30°C packed in unopened original containers .
- CYMEL® 250 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.
