Technical Details & Test Data
- Backbone Polymer Selection
CYMEL NF 3041 crosslinking agent is a very effective for alkyd, polyester and acrylic polymers containing primary hydroxyl functionality. Reactivity with secondary hydroxyl sites is limited under ambient cure. CYMEL NF 3041 crosslinking agent has a high Tg and should be paired with softer polyols (Tg < 30°C) to avoid film checking or cracking. The equivalent weight of CYMEL NF 3041 is ~110 g/eq (solids basis). Binder ratios can vary from 85/15 to 70/30 depending upon the equivalent weight of the polyol.
- Catalysis
For ambient or low bake applications with alkyd resins, it is recommended to use 2.0% CYCAT® 500 based on weight of total binder solids. Other polyols, like acrylic resins and polyester resins, can tolerate CYCAT 4040 catalyst without blooming. The acidity of other formulation components may affect the reaction rate and should be evaluated in combination with the catalyst.
- Stability
FORMULATION STABILITY
Catalyzed pot life can be extended by the addition of 10 to 20% primary alcohol on total binder solids. Methanol or ethanol is preferred to ensure early hardness development and sandability. The coatings demonstrate very good flow, gloss, early film hardness, early print resistance and chemical resistance.
STORAGE STABILITY
CYMEL NF 3041 crosslinking agent has a shelf life of 365 days from the date of manufacture when stored at temperatures below 32°C. Although lower temperatures are not detrimental to stability, the viscosity of the product will increase possibly making the crosslinking agent difficult to pump or pour. Product viscosity can be returned to normal by gentle warming, however, care should be taken to avoid excessive localized heating as this can result in an irreversible increase in viscosity
