Excellent compatibility with conventional solvent-borne decorative and industrial coatings systems.
Improved storage stability compared to traditional cobalt naphthenate solutions.
Designed to meet global regulatory expectations for heavy metal content in industrial coating formulations.
Interior and exterior decorative solvent-borne alkyd paints.
Industrial maintenance coatings for metal substrates.
Wood finishing systems including varnishes and stains.
Printing ink formulations requiring controlled drying kinetics.
Marine and protective coatings where balanced through-dry performance is critical.

Q1: What is the primary function of ADDITOL P964 in coating formulations?
A: ADDITOL P964 is a highly reactive, low-viscosity catalyst designed to accelerate crosslinking reactions—particularly between hydroxyl-functional resins and melamine or urea formaldehyde crosslinkers—in thermosetting coatings.
Q2: How does ADDITOL P964 compare to traditional acid catalysts in terms of storage stability and pot life?
A: Unlike strong mineral acid catalysts, ADDITOL P964 offers improved shelf stability in premixed systems and provides extended pot life under ambient conditions while still delivering efficient cure performance at elevated temperatures.
Q3: Is ADDITOL P964 compatible with high-solids and water-reducible coating systems?
A: Yes—ADDITOL P964 demonstrates good compatibility with both solvent-borne high-solids systems and selected water-reducible formulations, though compatibility should always be verified experimentally due to sensitivity to pH and ionic content.
Q4: What is the typical dosage range for ADDITOL P964 in industrial baking finishes?
A: Dosage is formulation-dependent, but ADDITOL P964 is typically used at low concentrations—generally ranging from 0.1% to 2% by weight relative to total resin solids—to balance reactivity, film formation, and final film properties.
