CYMEL® 1158 Resin

CASE Ingredients Functions
Crosslinking Agent

CYMEL® 1158 Resin serves as a crosslinking agent in the CASE Ingredients range. Tailored for the automotive and transportation sectors, it's apt for automotive OEM coatings and finishes. This clear liquid resin is compatible with acrylics, alkyds, epoxies (EP), and polyesters, particularly for top coat applications on metal surfaces.

Catalysis

CYMEL 1158 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® 296-9 catalyst based on total resin solids is recommended.

Stability

FORMULATION STABILITY; The stability of solvent-borne systems containing CYMEL 1158 resin can be enhanced by the addition of primary alcohols, amines, or a combination of these. Low molecular weight primary alcohols such as ethanol or n-butanol are most effective. Recommended amines are TEA or DMEA at a concentration of 0.5-1.0% on total binder solids.; STORAGE STABILITY; CYMEL 1158 resin has a shelf life of 720 days from the date of manufacture when stored at temperatures below 32°C. Although low 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 1158 resin is an 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 1158 resin should be determined experimentally, ratios of 25 to 35% based on resin solids are typically most effective.
