Technical Details & Test Data
- Backbone Polymer Selection
CYMEL 5010 resin contains a combination of butoxymethyl, methylol and imino functionalities, making it a very effective crosslinker for backbone polymer resins containing hydroxyl, carboxyl, or amide functional groups, such as those found on alkyd, polyester or acrylic resins. In addition to crosslinking, CYMEL 5010 resin will self-condense readily resulting in films with excellent film hardness. Although the optimum level of CYMEL 5010 resin should be determined experimentally, ratios of 25 to 35% based on resin solids are typically most effective.
- Catalysis
CYMEL 5010 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 systems containing CYMEL 5010 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.
STORAGE STABILITY
CYMEL 5010 resin has a shelf life of 1080 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.
