BASF Acronal 4F from BASF's Acronal series solvent-based plasticizing modification-specific acrylic resin range is a solvent-based high-performance plasticizing modified resin based on butyl acrylate resin. With significant solvent-free characteristics and solid content up to over 98%, this resin has excellent light stability and aging resistance
Efficient plasticizing modification - Can be directly used as plasticizer to replace traditional additives, significantly improving system flexibility and ductility, adapting to modification needs of diverse bonding systems.
Outstanding environmental resistance - Excellent light resistance and aging resistance, stable performance under long-term light and harsh environments, ensuring long-term service quality of end products.
Broad compatibility - Excellent compatibility with various resins such as nitrocellulose, polyvinyl chloride copolymers and natural resins, with high flexibility in formula preparation.
Solvent-based sealants: Plasticizing modification of solvent-based sealants for industrial and construction use, improving sealant flexibility and adhesion, suitable for sealing complex substrates.
Nitrocellulose coatings: Plasticizing modification of nitrocellulose coating systems, improving film flexibility and aging resistance, extending coating service life.
Reactive adhesives: Replacing traditional plasticizers for reactive adhesives, improving adhesive bonding strength and weather resistance.
