Overview
Dianal BR-107 is an acrylic resin with a moderate degree of hardness and flexibility, making it useful for creating durable adhesives and coatings used in packaging applications. Dianal BR-107 is supplied as a solid, nondusting bead that rapidly dissolves in a variety of solvents, including toluene, MEK, acetone, and PCBTF. Films formed with BR-107 have high resistance to weathering, yellowing, moisture, and attack from dilute acids and bases. Like all Dianal grades, BR-107 has a low degree of polydispersity, which helps improve weathering, brittleness, and toughness. It is typically used in solvent-based adhesive and heat seal coating formulations, where the balance of flexibility and toughness allows for the application of flexible plastic and foil lids and the development of strong bonds.
