Q1: What is the primary function of DIANAL BR-117 in coating formulations?
A: DIANAL BR-117 is a solution-grade acrylic resin designed primarily as a film-forming binder and rheology modifier in solvent-borne industrial coatings. It contributes to gloss development, substrate adhesion, and overall film integrity while supporting compatibility with common organic solvents and crosslinkers.
Q2: Is DIANAL BR-117 suitable for use in automotive refinish or OEM coatings?
A: Yes — DIANAL BR-117 is commonly employed in mid-to-high-solids solvent-based systems for automotive refinish applications, where it helps balance flow, leveling, and sandability. Its molecular architecture supports good compatibility with melamine and polyisocyanate crosslinkers used in these systems.
Q3: How does DIANAL BR-117 perform under UV exposure and weathering conditions?
A: As a non-yellowing acrylic resin, DIANAL BR-117 exhibits inherent resistance to UV-induced degradation and maintains color stability and gloss retention over time — making it well-suited for exterior-facing industrial and architectural coatings requiring long-term durability.
Q4: What solvents are recommended for diluting or processing DIANAL BR-117?
A: DIANAL BR-117 demonstrates good solubility in typical medium-to-slow evaporating aromatic and aliphatic hydrocarbons (e.g., xylene, Solvesso™ 100, mineral spirits), as well as ketones such as MEK and MIBK. Solvent selection should consider evaporation rate, VOC compliance requirements, and compatibility with other formulation components.
Q5: Can DIANAL BR-117 be blended with other resins, such as alkyds or polyester resins?
A: Yes — DIANAL BR-117 is formulated to offer broad compatibility with many conventional thermosetting resins, including alkyds, polyesters, and amino resins. Blending can be used to tailor drying speed, hardness development, flexibility, and chemical resistance, though compatibility testing under actual formulation conditions is recommended.
