Q1: What is the primary function of Borchi Kat LH10 in coating and ink formulations?
A: Borchi Kat LH10 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 the regulatory or handling concerns associated with traditional cobalt-based driers.
Q2: Is Borchi Kat LH10 compatible with waterborne systems?
A: Yes — Borchi Kat LH10 is formulated for compatibility with both solvent-borne and waterborne alkyd and hybrid resin systems. Its stable dispersion allows effective integration into emulsified or pseudo-solution architectures without phase separation or destabilization.
Q3: How should Borchi Kat LH10 be dosed in a typical formulation?
A: Dosage depends on formulation requirements, binder type, film thickness, and drying conditions. It is typically used at low concentrations — generally ranging from 0.1% to 2% by weight relative to total resin solids — and should be added during the let-down stage under moderate agitation.
Q4: Does Borchi Kat LH10 contribute to yellowing or discoloration in clear coats?
A: No — unlike some transition metal driers, Borchi Kat LH10 exhibits excellent color stability and low tendency toward yellowing, making it suitable for high-clarity and white-pigmented systems where long-term chromatic integrity is critical.
