Technical Details & Test Data
- Backbone Polymer Selection
CYMEL 232 resin is a versatile crosslinking agent for a wide range of polymeric materials containing carboxyl, hydroxyl or amide functionalities such as acrylic, alkyd, polyester and epoxy resins. In water borne system Due to its hydrophobic nature, CYMEL 232 resin has to be dissolved initially in the organic phase of the water reducible backbone polymer.
- Catalysis
CYMEL 232 is an efficient cross-linking agent for hydroxyl, carboxyl, amine or amide functional polymers. The cross-linking reaction follows the reaction pathway for specific acid catalysis and requires strong acid catalyst such as CYCAT 4040 catalyst, CYCAT 600 catalyst and CYCAT 500 catalyst. Usually 0.2% to 0.4% strong acid on binder solids is recommended for a 15-20 minute bake schedule at 120°C to 150°C.
- Stability
FORMULATION STABILITY
In a formulated system, stability can be improved by the use of a blocked acid catalyst, or by the addition of a stabilizing alcohol to the formulation. Good stability has been obtained in high-solids systems by using 25% of the added solvent as primary alcohol and blocking the acid catalyst with 110% of the stoichiometric equivalent of an amine.
STORAGE STABILITY
CYMEL 232 resin has a shelf life of 540 days from the date of manufacture when stored at temperatures between 5°C and 30°C packed in unopened original containers. CYMEL 232 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.
