Additional Information
Properties
Medium Reactivity & Viscosity: Suitable for hand lay-up, filament winding, and conventional FRP fabrication.
High Hardness & Corrosion Resistance: Thanks to the aromatic ring structure of PTA.
Shock Resistance & Flexibility: Especially when modified with ether-containing diols or flexible monomers.
Excellent Sandability: Ideal for large-area blade coating applications like railway locomotives.Advantages of PTA-Based Resin
