Adiprene^® K blocked elastomers are stable at room temperature, offer controlled curing with outstanding pot life at processing temperatures, and are fast curing for high productivity. Adiprene^® K blocked elastomers are significantly less viscous that other CAP-blocked prepolymers due to the use of LF technology, making them easier to process into complex parts.

Adiprene^® K products are based on low free (LF) isocyanate prepolymer technology which reduces the free isocyanates that could be released during processing to below 0.1%. These products are blocked with ε-caprolactam (CAP), which has lower toxicity concerns than other blocking agents. Adiprene^® K blocked elastomers have lower hazard classifications and can deliver superior industrial hygiene.

Adiprene^® K blocked elastomers are formulated with specific curatives to tailor performance to meet customer needs. As a result of the lower viscosities and improved morphology, which come from using low free isocyanate technology, Adiprene^® K blocked elastomers can be formulated with non-traditional raw materials, such as more viscous polyols or new curative types, enabling properties that are not possible with conventional prepolymers.

Benefits:

• LF technology for improved industrial hygiene and lower hazard classifications
• 1K system to avoid mixing and handling
• Controlled cure
• Enhanced performance with non-traditional raw materials

Uses:

• Impregnating fabric belts
• Large or complex cast parts
• Rotomoulding
