Q1: What is the primary particle morphology and visual effect of DOROLAN 35 1?
A: DOROLAN 35 1 features spherical aluminum particles with a controlled size distribution, delivering a bright, uniform metallic sheen and excellent orientation in coating films. Its spherical shape enhances flow behavior and contributes to smooth, defect-free finishes in solvent-based and high-solids systems.
Q2: Is DOROLAN 35 1 suitable for water-based coatings?
A: While primarily optimized for solvent-borne and high-solids systems, DOROLAN 35 1 can be incorporated into select water-based formulations using appropriate dispersants and stabilization protocols. Performance—especially dispersion stability and metallic effect—must be validated per specific formulation due to its non-passivated aluminum surface.
Q3: How does DOROLAN 35 1 compare to flake-type aluminum pigments in terms of application versatility?
A: Unlike traditional flake pigments, the spherical morphology of DOROLAN 35 1 offers improved rheological compatibility, reduced settling, and enhanced compatibility with automated application equipment—including airless spray and electrostatic systems. It also provides more isotropic reflectivity, making it especially valuable where consistent appearance across complex geometries is required.
Q4: What are key handling precautions during processing?
A: As with all uncoated aluminum pigments, DOROLAN 35 1 requires careful handling to avoid mechanical degradation and oxidation. Avoid high-shear dispersion methods unless validated, and minimize exposure to moisture, strong acids, or oxidizing agents during storage and incorporation. Use inert gas blanketing during milling or extended storage when feasible.
