Allnex ADDITOL P 890 Leveling Agent – Frequently Asked Questions (FAQ)

Q1: What types of coating systems is ADDITOL P 890 best suited for?

A: ADDITOL P 890 is specifically designed for solvent-borne and high-solids industrial coatings, including automotive refinish, coil, and general metal finishing systems. It performs well in both thermosetting acrylic, polyester, and epoxy-based formulations where excellent flow, leveling, and substrate wetting are required.

Q2: How does ADDITOL P 890 compare to silicone- or fluorosurfactant-based leveling agents?

A: Unlike silicone- or fluorosurfactants, ADDITOL P 890 is a non-silicone, polyacrylate-based additive that provides robust leveling without risking recoatability issues, cratering, or intercoat adhesion problems. It offers good compatibility across a broad range of resin systems and minimizes the risk of surface defects associated with low-surface-energy additives.

Q3: Is ADDITOL P 890 compatible with pigmented systems and metallic effect coatings?

A: Yes — ADDITOL P 890 demonstrates good compatibility with organic and inorganic pigments, as well as aluminum and mica-based effect pigments. It helps reduce orange peel and improves uniformity in metallic and pearlescent coatings without negatively affecting orientation or flop.

Q4: What is the recommended addition method and timing during formulation?

A: ADDITOL P 890 should be added during the let-down stage, after pigment dispersion and before crosslinkers or catalysts. It is typically dosed at low concentrations and benefits from gentle mixing to ensure homogeneous distribution without excessive shear, which could affect performance.

Q5: Does ADDITOL P 890 impact pot life or cure behavior in thermosetting systems?

A: ADDITOL P 890 is chemically inert under typical curing conditions and does not interfere with common crosslinking reactions (e.g., melamine, isocyanate, or blocked isocyanate systems). It generally has no measurable effect on pot life, gel time, or final film hardness when used within recommended dosage ranges.
