Introduction
Product Introduction
STD7730 is a two-component, solvent-free epoxy structural adhesive with high thixotropic paste consistency, suitable for mechanical dispensing. After application at room temperature, it is cured by heating at 70-80°C and achieves optimal performance upon cooling. Designed for bonding ultra-large wind turbine blades, offshore wind turbine blades, and similar large composite structures.
Characteristics & Applications
Characteristics:
- Excellent thixotropy and anti-sagging properties
- Long open time
- Low density, high toughness, and strength
Applications:
- Bonding for ultra-large epoxy FRP wind turbine blades
