CYMEL® 370 Resin
- CASE Ingredients Functions
- Crosslinking Agent
CYMEL® 370 Resin acts as a crosslinking agent within the CASE Ingredients' monomers and intermediates and chain extenders and crosslinkers segments. Specifically tailored for the paints and coatings sector, this clear liquid is adept for industrial coatings and furniture coatings, including primer applications in both solventborne and waterborne formulations.

- Catalysis
CYMEL 370 resin may not require the addition of an acid catalyst to the formulation to obtain effective cure. In many instances, the acidity of the backbone polymer in the formulation is sufficient to catalyze the reaction under normal baking conditions (15-20 minutes at 120-150°C). If catalyst addition is required, then 0.5-1.0% of CYCAT® 4040 catalyst or CYCAT 296-9 catalyst based on total resin solids is recommended.
- Stability
FORMULATION STABILITY; The stability of solvent-borne systems containing CYMEL 370 resin can be enhanced by the addition of primary alcohols, tertiary amines, or a combination of these. Low molecular weight primary alcohols such as ethanol and n-butanol are most effective. Recommended amines are TEA or DMEA at a concentration of 0.5-1.0% on total binder solids. For best stability in waterborne systems, a pH of 7.5-8.5 should be maintained using tertiary amines only.; STORAGE STABILITY; CYMEL 370 resin has a shelf life of 1080 days from the date of manufacture when stored at temperatures below 32°C. 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

- Backbone Polymer Selection
CYMEL 370 resin contains a combination of methoxymethyl and methylol functionalities, making it a very effective crosslinker for backbone polymer resins containing hydroxyl, carboxyl, and amide functional groups, such as those found on alkyd, polyester or acrylic resins. Although the optimum level of CYMEL 370 resin should be determined experimentally, ratios of 25 to 35% based on resin solids are typically most effective.
