Hycryl
Hycryl is a specialized acrylic copolymer resin designed primarily for industrial and cosmetic applications. It appears as a white to off-white powder or granules with excellent film-forming, adhesive, and thickening properties. Known for its compatibility with a wide range of solvents and plasticizers, Hycryl 77 provides excellent clarity, flexibility, and durability in coatings, adhesives, and personal care formulations. Its balanced molecular weight and functional groups enable it to deliver strong binding and aesthetic properties in both aqueous and solvent-based systems.
Hycryl
Primary Uses
- Cosmetics and Personal Care
- Used as a film former in hair styling products (gels, sprays, mousses) to provide hold and flexibility without stickiness.
- Functions as a thickening agent and rheology modifier in creams, lotions, and gels for improved texture and stability.
- Employed as an adhesive binder in mascaras and eyeliners to enhance product longevity and water resistance.
- Acts as a binder in nail polishes to improve gloss, adhesion, and chip resistance.
- Industrial Coatings and Adhesives
- Utilized as a binder resin in solvent-based and water-based coatings, providing good adhesion to various substrates including metals, plastics, and glass.
- Used in adhesive formulations for packaging, labels, and laminates requiring strong, flexible bonds.
- Functions as a thickener and stabilizer in paints and varnishes to improve flow and prevent sagging.
- Printing Inks
- Incorporated as a resin binder in flexographic and gravure inks to enhance adhesion, drying, and print quality.
- Textile Finishing
- Used in textile coatings and finishes to improve fabric hand, durability, and water resistance.
Secondary Uses
- Pharmaceuticals
- Explored as a film-forming agent in controlled-release tablet coatings to modulate drug release profiles.
- Packaging
- Applied in coatings for flexible packaging films to improve barrier properties and printability.
- Construction
- Used as a component in specialty sealants and caulks for improved adhesion and flexibility.
