CYMEL® NF 3030 resin is a water-supplied, formaldehyde-free crosslinking agent designed for 2-component, ambient or forced cure, water-borne conversion varnishes in industrial wood applications. When paired with an amine-free acrylic emulsion, it enhances catalyzed pot life compared to isocyanate-based varnishes. The resulting coatings boast excellent appearance, early hardness, resistance properties, and hot/cold cycle flexibility. As a crosslinking agent, it supports VOC-free, sustainable, formaldehyde-free, solvent-free, and environmentally friendly labeling claims. Ideal for wood coatings and finishes, it finds applications in furniture coatings and industrial coatings.

Technical Details & Test Data

Backbone Polymer Selection

CYMEL NF 3030 resin is an effective crosslinking agent for alkyd, polyester and acrylic polymers containing primary hydroxyl functionality. Reactivity with secondary hydroxyl sites is limited under ambient cure. CYMEL NF 3030 resin 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 3030 is ~85 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, it is recommended to use 1.0% CYCAT® 4040 catalyst based on weight of total binder solids. For high bake applications, the addition of catalyst isn’t required as long as the acid number of the primary film former is >5.
