Description du produit
High Tg Thermoplastic Acrylic Resin For Durable Plastic Coatings & PVC Inks
SA-1737 is a solid thermoplastic acrylic resin engineered for applications demanding exceptional hardness, heat resistance, and long-term outdoor durability.
Product Profile & Core Positioning
This resin is positioned as a high-performance binder, particularly suitable for outdoor plastic coatings and high-wear PVC inks, where resistance to heat, weathering, and physical abrasion is critical.
Key Properties Analysis
  • High Heat Resistance & Hardness: Exceptional Glass Transition Temperature (Tg) of 105°C provides superior heat resistance, minimal thermal softening, and ability to form very hard, rigid films essential for high-temperature applications and scratch resistance.
  • Molecular & Rheological Profile: High molecular weight (Mw 50,000 g/mol) combined with low Intrinsic Viscosity (IV 0.18) facilitates good solubility and favorable solution rheology, enabling higher solid content formulations while maintaining workable viscosity.
  • Enhanced Reactivity & Adhesion: Acid Value of 12 mgKOH/g increases resin polarity and hydrogen bonding potential, directly translating to improved adhesion on difficult substrates and enhanced compatibility with pigments and other resin components.
  • Solubility & Compatibility: Ready solubility in ketones, esters, and aromatic hydrocarbons offers broad formulation flexibility. Excellent compatibility with nitrocellulose, CAB, and plasticizers allows easy adjustment of flexibility, drying speed, and finish properties.
Primary Application Advantages
  • Plastic Paints (Outdoor Use): High Tg, hardness, and excellent weather resistance make it ideal for coatings on outdoor plastic parts including automotive trim, garden equipment, and signage where gloss retention and UV degradation resistance are vital.
  • PVC Inks: Provides necessary hardness, adhesion, and fast solvent release required for durable prints on PVC substrates such as banners, tarpaulins, and packaging materials.
Conclusion
SA-1737 is a high-Tg, functional grade solid acrylic resin. Its core value lies in providing a balance of extreme hardness/heat resistance (from high Tg), strong substrate adhesion (from higher acid value), and formulation versatility, making it a robust choice for demanding exterior-grade plastic coatings and performance inks.
