Hardener (Non Yellowish) (Similar to RN)/ TPUA-ACFN
Advantage
- Similar to RN
- NCO: 4.8 ± 0.2% by weight
- Appearance: colorless to light color clear liquid
- Non-yellowing
- Enhance the bonding strength of adhesive
- Increase the heat resistance of adhesive
| Application | |||
|---|---|---|---|
| After the addition of TPUA-ACFN (NON YELLOWISH), the ready-to-use double-component adhesive should be applied within a period (pot life) which is determined not only 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, it may become increasingly difficult to apply and its viscosity increases rapidly until irreversible gelling ultimately occurs. |
| Description | |||
|---|---|---|---|
| The almost colorless TPUA-ACFN (NON YELLOWISH) is designed as curing agent for adhesive based on hydroxyl polyurethane, natural and synthetic rubber; owing to TPUA-ACFN (NON YELLOWISH) features good hot-resistance, it is particularly suitable for light-color polyurethane adhesive system. Because the solvent is ethyl acetate, TPUA-ACFN (NON YELLOWISH) can be used in those countries where the use of methylene chloride is restricted. |
| Typical Properties | |
|---|---|
| Chemical composition | Solution of approx. 27% Polyisocyanate in 73% ethyl acetate |
| Intrinsic color | Almost colorless to light-color clear liquid |
| NCO content, % by weight | 4.8±0.2 |
| Solubility | Soluble in various esters, ketones and aromatic solvents |
| Storage stability | Reacts readily with moisture; for the best performance it should be kept dry and stored at temperatures between (5℃~32℃) |
| Performance | |||
|---|---|---|---|
| The film of adhesive and coating film mixed by TPUA-ACFN (NON YELLOWISH) is difficult to become yellow after exposure to UV light and heat. So TPUA-ACFN (NON YELLOWISH) shows good bonding strength in PVC with much plasticizer, SBR with plenty of oil, coating leather, silk and so on. |
| Suggested Additions | |||||||
