L117 Wrinkle Finish Agent( outdoor) is a sulfonic acid catalyst, which can make the surface of the polyurethane coating shrink strongly to form crocodile patterns of different sizes. Compared with indoor wrinkle finish agent, the outdoor crocodile pattern is larger, more obvious and stable. |
● L117 outdoor wrinkle finish agent should be used in combination with hydroxyl polyester and curing agent 1174. ● Dosage is 0.6-1% of total formula amount, mixed with other material and extrude. ● Filler quantity should be small or don't add for big pattern. ● Dry blend turtle shell agent L118 can make pattern more coherent, easy to spray. ● It has selectivity to hydroxy polyester. From the perspective of the polyester we tested, Kinte 7805 and Chan Sieh 1000H are more suitable.
Reference formula:
| Big texture size | Medium texture size | Remarks | Hydroxyl Polyester | 80 | 60 | Chan Sieh 1000H.Kinte 7805 | Ultrafine Barium | 9 | 30.6 | More filler, smaller texture size Less filler, bigger texture size | Curing Agent L1174 | 6.4 | 4.8 | Dosage is 8% of polyester | Texture Modifier L1173 | 3 | 3 | Dosage is 3% of total formula | Wrinkle Finish Agent L117 | 0.6 | 0.6 | Dosage is 0.6-1% of total formula | Pigment | 1 | 1 |

| Turtle shell agent L118 | 0.2% | 0.2% | Dry blending, can make texture more coherent, easy to spray but smaller texture size. | Extruding Temperature | 120-130℃ | Extruding temperature should be 10 ℃ higher than usual, well mixing will obtain better extrusion effect | Baking Temperature | 210℃×15min |
| Thickness | 100um | Big texture size,spray thicker | Impact | 50Kgcm |
| Bending | 2mm |
|
Notice ● Higher extruding temperature,120-130℃ better texture results. ● Higher baking temperature, 210℃*20min,better mechanical properties.
