2017 HIGH QUALITY HOT SALE HARTDUR F256

The almost colorless HARTDUR C528 is designed as curing agent for adhesive based on hydroxyl polyurethane, natural and synthetic rubber

Typical Properties:

Applications: 

After the addition of HARTDUR C528, 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, 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 gelling ultimately occurs.

Suggested Additions:

For curing adhesive of 100 parts by weight (p.b.w.) based on:
Graft-Choloroprene rubber (rubber content approx. 16%): 3-5% p.b.w. HARTDUR C528
Choloroprene rubber (rubber content approx. 20%): 5-7% p.b.w. HARTDUR C528
Hydroxyl polyurethane (polyurethane content approx. 15%): 3-5% p.b.w. HARTDUR C528
