Question 1

How does CFDB-100 replicate cobalt drying performance without cobalt?

Accepted Answer

CFDB-100 combines manganese (primary surface drier), zirconium (through-drier promoter), calcium (auxiliary co-drier), and bismuth (surface modifier). The synergistic metal ratio is optimized to replicate cobalt's radical-initiation efficiency across both surface-dry and through-dry stages in solventborne alkyd systems.

Question 2

Is CFDB-100 suitable for waterborne alkyd emulsions?

Accepted Answer

CFDB-100 is formulated for solventborne alkyd systems. For waterborne alkyd emulsions, a purpose-built water-dispersible cobalt-free drier is required due to HLB and emulsion stability requirements in aqueous media. Contact our technical team for a waterborne-compatible alternative.

Question 3

What regulatory advantage does switching to CFDB-100 provide?

Accepted Answer

Cobalt compounds are classified as CMR (carcinogenic, mutagenic, reprotoxic) under EU REACH/CLP, imposing SDS labelling obligations, occupational exposure limits, and potential future restriction. CFDB-100 eliminates these obligations and supports product registration in regulated markets including the EU, UK, and South Korea.
