Bergolin Putty 4D9700-HighTemp

2-Component Polyurethane Repair Putty

Fast Repairs. High-Temperature Performance. Built for Wind Energy.

Bergolin Putty 4D9700-HighTemp is a solvent-free, pigmented, elastic 2-component polyurethane repair compound developed specifically for wind turbine rotor blades and high-performance GRP structures. Designed for demanding outdoor environments, it delivers excellent UV resistance, strong mechanical performance, and durable adhesion — even under extreme temperature conditions.

Its thixotropic consistency allows for controlled filling and precise surface leveling, making it ideal for fast, professional composite repairs in high-heat environments.

Recommended Applications

• Repair and leveling of GRP surfaces

• Wind turbine rotor blade maintenance

• Composite structure surface restoration

• Applications exposed to high UV and weather stress

• Filling work requiring elasticity and flexibility

• Industrial wind energy manufacturing and service operations

Suitable for processing at ambient temperatures up to +45°C.

Key Advantages

• Solvent-free and virtually VOC-free

• High elasticity for flexible composite components

• Excellent UV and weather resistance

• Fast processing and sanding times

• Designed for high-temperature application conditions

• Strong adhesion to GRP and composite substrates

Performance in High-Temperature Environments

Engineered for hot climate conditions and elevated surface temperatures, 4D9700-HighTemp maintains workability and performance even when applied between +25°C and +45°C. This makes it particularly valuable for field repairs on rotor blades and outdoor composite structures where surface heat can be significant.
