Q1: What are the primary application areas for DIANAL BR-106?
A: DIANAL BR-106 is widely used in high-performance thermoplastic coatings for automotive trim, appliance finishes, and industrial plastic substrates where excellent gloss retention, UV resistance, and substrate adhesion are required. It is also employed in solvent-based inks and overprint varnishes demanding clarity and rapid film formation.
Q2: How does BR-106 compare to other acrylic resins in terms of solubility and film hardness?
A: BR-106 exhibits good solubility in common organic solvents such as esters, ketones, and aromatic hydrocarbons, enabling formulation flexibility. Its thermoplastic nature delivers a balanced combination of film hardness and flexibility—softer than many crosslinkable acrylics but more resistant to cold flow and blocking than lower-Tg alternatives.
Q3: Is BR-106 suitable for use in food-contact applications?
A: DIANAL BR-106 is not pre-approved for direct food-contact applications. Formulators must conduct full regulatory evaluation—including migration testing and compliance verification—based on final formulation, processing conditions, and intended end-use, as resin suitability depends on the complete system rather than the base polymer alone.
Q4: What is the recommended storage condition for BR-106?
A: Store BR-106 in its original sealed container in a cool, dry, and well-ventilated area, away from direct sunlight, heat sources, and strong oxidizing agents. Prolonged exposure to elevated temperatures or humidity may affect handling properties or solution stability.
