More possibilities with the right POLYOL

When coatings, potting compounds or technical polyurethane components must withstand demanding conditions over a long term, choosing the right polyol is critical ensuring reliability and minimizing the risk of failure.

We offer two highly functional polyester polyols, ROKRAPOL RK 6989 and ROKRAPOL RK 8122, designed for applications where hardness, durability and long-term performance are essential.

However, each product is optimized for different performance priorities.

• ROKRAPOL RK 6989 — Maximum Crosslinking for Outstanding Performance
  Its high hydroxyl value, reactivity, and crosslink density enable the development of polyurethane systems with exceptional hardness, thermal stability and chemical resistance.

• ROKRAPOL RK 8122 — is designed for demanding outdoor applications
  Its high mechanical strength, good weathering resistance and excellent resistance to yellowing make this polyester polyol an ideal choice for durable outdoor protective coatings.

Which property is most critical for your polyurethane application? Let us help you identify the optimal polyol platform for your specific requirements.
