Products Description
BDC is a styrene-butadiene copolymer containing epoxy groups with a yellowish appearance.
BDC is actually an acronym for “Butadiene Diepoxide Coupled” and refers to a type of styrene-butadiene copolymer that contains epoxy groups. This copolymer is known for its yellowish appearance, which can be attributed to the presence of the epoxy groups.
Styrene-butadiene copolymers are commonly used in a variety of applications, including adhesives, coatings, and sealants. The addition of epoxy groups to the copolymer can improve its adhesive properties, making it more effective at bonding to a variety of surfaces.
The yellowish appearance of BDC is a result of the chemical structure of the epoxy groups. These groups contain aromatic rings that absorb light in the visible spectrum, giving the copolymer a yellowish tint. The color of BDC can vary depending on the amount of epoxy groups present in the copolymer and the specific conditions of the manufacturing process.
Overall, BDC is a valuable material for improving the adhesive properties of styrene-butadiene copolymers. Its yellowish appearance is a characteristic of its chemical structure and can be an advantage in certain applications where color is not a concern.
