HARTDUR CFN-2 (RN)
| Common Name: | RN |
| Chemical Composition: | Contains 27% polyisocyanate and 73% ethyl acetate (EAC) |
HARTDUR CFN-2 (RN) is a polyisocyanate diluted with ethyl acetate. It provides excellent heat resistance and is highly resistant to color change. HARTDUR CFN-2 also improves the adhesion of different substrates that are difficult to adhere to, such as PVC containing plasticizers, SBR with high oil content, and the surfaces of leather, silk, etc.
Solubility
Soluble in various esters, ketones, and aromatic solevents.
Package
0.75 KG / Aluminum bottle; 20 Bottles / Carton (15kgs)
180 KG / Iron Drum
It can be packaged on demand. Please inquire.
Hartdur CFN-2 is a two-component adhesive. After adding a certain proportion of Hartdur CFN-2 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.
