P - EPOX - 2800 X 65 |
|
|
 |
|
| High Performance Epoxy Resin: P - EPOX - 2800 x 65 is unique “Epoxy Ether” resin developed by reacting alkyl phenol with bis- phenol epoxy resin & further modified to enhance the performance to protect the substrate in adverse climatic conditions. |
|
| Applications : |
|
- One pack air drying epoxy composition
- Modification of standard two pack epoxy coatings
- Two pack epoxy- PU hybrid coating
- One pack stoving epoxy with blocked isocynates
- One pack stoving epoxy coating with MF / UF / phenolic resins

|
| Advantages : |
| I) One Pack Systems : |
| |
a) User friendly protective coatings for mechanically cleaned surfaces could be developed |
| |
b) Fast drying one pack epoxy systems against chlorinated rubber / vinyflex could be developed which gives excellent |
| |
corrosion, acid & alkali resistance |
|
| II) Modification of Standard Epoxy Two Pack Coating (Modification up to 30% & Advantages against std. Two Pack Epoxy Systems) : |
| |
a. Cost reduction |
| |
b. Gives good acid, alkali & corrosion resistance |
| |
c.Improves surface wetting properties for maintenance primers/coatings |
| |
d. Higher workable pot life |
| |
e. Increases recoating interval incase of primers & mid coats |
| |
f. Better pigment dispersion & wetting during production |
|
| III) Two Pack Epoxy - PU Hybrid Coating |
| |
a. Low temperature curing is better than epoxy / phenalkamine systems |
| |
b. Very good flexibility |
| |
c. Very good solvent & chemical resistance |
