| Application |
|---|
APU-70-25I is a non-yellowing type of Polyisocyanate and similar to Bayer Desmodur RN. It shows excellent bonding properties on PU adhesives. APU-70-25I has widely used as a crosslinker when high temperature stability is required. The crosslinker is added just before application of the adhesive and stirred completely about minimum 2-3 minutes.
The pot life of the formulation should be used within 2-4 hours |
