Product Introduction
STD8211 biodegradable hand lay-up resin is suitable for composite hand lay-up processes, structural components (e.g., wind turbine blades), shell manufacturing, and reinforcement. 8211-1 is designed for low-temperature winter environments, while 8211-2 is optimized for high-temperature summer conditions.
Product Features
Rapid curing at low temperatures; two curing speeds adapted for different temperature environments.
Applicable Processes
Hand lay-up, RTM (Resin Transfer Molding), and small product filament winding.
