Thermoplastic Acrylic Resin For Heat-seal Varnish/Lacquer Application

  SA-523 is a thermoplastic acrylic resin designed for heat-seal lacquer systems, offering reliable sealing performance and strong adhesion to metal substrates. Based on a MMA and n-BMA copolymer, it provides good color development, excellent toughness, and stable film formation during heat sealing.

  In heat-seal applications, the resin softens and flows evenly under heat, forming a continuous sealing layer on aluminum and aluminum-plated films. After cooling, it delivers strong adhesion, good peel strength, and durability. Its high softening point ensures good heat resistance and minimizes blocking during storage and processing.

• Good color development
• Strong adhesion
• Good weather resistance
• Good toughness, good metal adhesion
• Good compatibility with chloroether resin, chloroacetic acid, NC, some liquid polyurethane

1. When used with binary or ternary chloroacetic acid, it can be used in various aluminum-plated films and pure aluminum.

2. When used with ternary chloroacetic acid, it can be used for general matte oil, paper towel ink, and pure surface printing ink.

• SA523 is a solid resin supplied as a white powder or beads.
• Packed in 25Kg/bag
