HOT SALE HARTDUR C528
The almost colorless HARTDUR C528 is designed as curing agent for adhesive based on hydroxyl polyurethane, natural and synthetic rubber
Typical Properties:
Chemical composition | Approx.26% aromatic polyisocyanate in 74% ethyl acetate |
Intrinsic color | almost colorless liquid |
NCO% | 6.0±0.2 |
Solubility | Soluble in various esters, ketonesand aromatic solvents |
Storage stability | Reacts readily with moisture; forbest performance it should be kept dry and stored at temperatures between 5℃ and 32℃. |
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
