Q1: What types of coating systems is Levaslip 8629 best suited for?
A: Levaslip 8629 is specifically designed for solvent-borne and high-solids industrial coatings, including automotive refinish, coil coatings, and general metal finishing systems. It performs well in formulations where low surface tension, good substrate wetting, and defect-free film formation are critical.
Q2: How does Levaslip 8629 compare to silicone-based leveling agents?
A: Unlike many silicone additives, Levaslip 8629 is a non-silicone, acrylic-based leveling agent—offering excellent compatibility with sensitive systems and minimizing risks such as recoatability issues, cratering, or intercoat adhesion problems often associated with silicones.
Q3: What is the recommended dosage range for optimal performance?
A: Levaslip 8629 is typically used at low concentrations, generally ranging from 0.1% to 2.0% by weight of total formulation, depending on resin type, solvent composition, and desired surface appearance. Optimal dosage should be determined through lab-scale evaluation under actual production conditions.
Q4: Is Levaslip 8629 compatible with common crosslinkers and catalysts used in industrial coatings?
A: Yes, Levaslip 8629 demonstrates broad compatibility with melamine formaldehyde, polyisocyanate, and carbodiimide crosslinkers, as well as common acid and metal-organic catalysts. Compatibility testing is still recommended when introducing it into new or highly reactive systems.
