Q1: What is the primary function of Borchi Kat 24 in coating and ink formulations?
A: Borchi Kat 24 is a cobalt-free, heavy-metal-free drier catalyst designed to accelerate the oxidative crosslinking of alkyd resins and other air-drying binders. It promotes efficient surface and through-dry without contributing to discoloration or film brittleness commonly associated with traditional cobalt driers.
Q2: Is Borchi Kat 24 compatible with waterborne systems?
A: Yes, Borchi Kat 24 is formulated for compatibility with both solvent-borne and water-reducible alkyd systems. Its stable chelated structure minimizes hydrolysis risk and supports consistent performance in low-VOC and hybrid formulations.
Q3: How should Borchi Kat 24 be dosed in a typical alkyd formulation?
A: Dosage depends on formulation requirements and desired dry speed, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight relative to the binder solids. Optimization through small-scale trials is recommended to balance drying efficiency, film integrity, and storage stability.
Q4: Does Borchi Kat 24 require activation or special handling during incorporation?
A: No special activation is required. Borchi Kat 24 can be added directly during the let-down stage under standard mixing conditions. For optimal dispersion, it is advisable to add it after the main binder and before solvents or thinners, with moderate agitation to ensure homogeneity.
