Compare the models
| Model | Tensile strength | Elongation at break | Skin time | Shore A |
|---|---|---|---|---|
| KA518 | 3.5 | 320 | 30 | 65 |
| KA520 | 4.5 | 450 | 40 | 60 |
| KA530F | 6.5 | 450 | 15 | 58 |
Typical values from the catalogue; the batch record carries the measured result.
Choosing one
Choose by the bay, not by the tensile figure. A workshop that can hold the vehicle uses KA518; throughput and winter work need KA530F and its 15-minute skin; a coach with an 8 m glass needs KA520 and its 40 minutes. The grades span 3.5–6.5 MPa, but the schedule decides more jobs than the strength number.
Tell us the vehicle type, glass perimeter and bay temperature and we will name the grade. ryan@pu-karmind.net
