Description

Shellac, Polymer With Styrene CAS NO 68513-93-9 is a synthetic resin derived from the natural polymer shellac, modified through copolymerization with styrene. This modification enhances its film-forming properties, chemical resistance, and durability, making it a versatile and high-performance material for demanding industrial applications. It is particularly valuable for manufacturers in the coatings, adhesives, and specialty polymer sectors seeking a robust, natural-based resin with improved mechanical strength and processing characteristics.

Application

• Industrial Coatings: Used in high-performance protective and decorative coatings for metal, wood, and plastic substrates, offering excellent gloss and resistance.
• Adhesives and Sealants: Serves as a key resin in formulating strong, durable adhesives for packaging, construction, and automotive assembly.
• Printing Inks: Acts as a film-forming agent and gloss enhancer in specialty printing inks, including overprint varnishes.
• Microencapsulation: Employed as a wall material for the controlled release of active ingredients in agrochemicals, pharmaceuticals, and fragrances.
• Electronics: Used in conformal coatings and potting compounds to protect electronic components from moisture and environmental stress.
• Leather Finishing: Provides a tough, flexible, and glossy topcoat for leather goods and upholstery.
