Borchers Borchi Kat 315 Catalyst – Frequently Asked Questions (FAQ)

Q1: What is the primary chemical function of Borchi Kat 315 in coating and ink formulations?

A: Borchi Kat 315 is a cobalt-free, heavy-metal-free oxidation catalyst designed to promote efficient air-drying of alkyd- and oil-based systems through enhanced autoxidation of unsaturated fatty acid chains. It functions as a redox-active metal complex that accelerates peroxide decomposition and free radical generation without contributing to VOC emissions or regulatory concerns associated with traditional driers.

Q2: How does Borchi Kat 315 compare to conventional cobalt driers in terms of drying performance and safety profile?

A: Unlike cobalt-based driers, Borchi Kat 315 delivers balanced through-dry and surface-dry characteristics while eliminating cobalt-related health and environmental hazards. It offers improved compatibility with modern low-VOC formulations and reduced risk of wrinkling or premature skinning—particularly in high-solids or solvent-reduced systems where cobalt can cause instability.

Q3: Is Borchi Kat 315 suitable for use in food-contact coatings or sensitive applications requiring regulatory compliance?

A: Borchi Kat 315 is formulated without heavy metals, halogens, or substances listed under major restricted substance lists (e.g., REACH SVHC candidates, RoHS). While it is not pre-approved for all food-contact applications, its composition supports compliance pathways for coatings intended for indirect food contact when used within recommended dosage ranges and validated in final formulation testing.

Q4: What are the recommended handling and storage conditions for optimal shelf life and performance?

A: Store in original sealed containers at temperatures between 5 °C and 30 °C, protected from direct sunlight and moisture. Avoid prolonged exposure to elevated temperatures or freezing conditions. When handled according to standard industrial chemical practices, Borchi Kat 315 maintains consistent catalytic activity for up to 24 months from date of manufacture.
