RN is a two-component adhesive. After adding a certain proportion of RN to the adhesive, the ready-to-use double-component adhesive should be applied within a period (pot life) which is determined not only by its content of rubber, but also by the other ingredients of the formulation (e.g. resins, antioxidants, solvents, and etc.). If the adhesive is not used within this period of time, it may become increasingly difficult to apply and its viscosity increases rapidly until irreversible gel time ultimately occurs. Thus, it’s no longer to be used.
Recommend Dosage:
For curing adhesive of 100 parts by weight (p.b.w.) based on:
Graft-Chloroprene rubber(rubber content approx. 16%) | 3-5% p.b.w. RN |
Chloroprene rubber(rubber content approx. 20%) | 5-7% p.b.w. RN |
Hydroxyl polyurethane(polyurethane content approx. 15%) | 3-5% p.b.w. RN |
