| Cleaning | Remove main portions mechanically („dab off”). Residuals can be cleaned with Bostik Solvent 280 or white spirit. |
| Safety Instructions | Observe the standard hygienic precautions for chemical goods when working with Butyl 1148. ? Do not eat, drink or smoke ? Avoid contact with eyes and skin ? Wash hands before breaks and after end of work ? Contact with melt causes thermal burns FOR FURTHER INFORMATION PLEASE REFER TO OUR SAFETY DATA SHEET |
| Stability | From -30°C to 80°C temperature and form stable. Butyl 1148 behaves thermoplastic: At low temperature the hardness increases, at high temperatures the mass becomes softer and tackier. Good aging resistance, especially under warm and humid conditions. Stable against water and saltwater in the range of pH 5 - 9. Not resistant against oil, grease, white spirit and other solvents. Butyl 1148 must be protected against permanent UV radiation. |
| Storage | Store under dry conditions, protect against mechanical deformation. Product is not affected by frost. Shelf life at least 24 months. |
| Adhesive Technology | HM BUTYL SEALANT – profiles |
| Colors | Black |
| Adhesion | Good adhesion to a variety of different materials. In contact with plastic materials a migration of plasticizer may occur – we recommend to carry out tests before application! Surfaces must be dry and mostly clean, free of dust, oil or grease. |
| Chemical Base | Synthetic rubber (IIR; PIB) |
| Density | 1,25 – 1,35 g/ml Pycnometer; 23°C (similar to DIN EN ISO 2811-1) |
| Melt Index | 130 - 170 ml/10 min 140°C;2,16 kg; 2 mm nozzle (similar to DIN EN ISO 1133-1 |
| Processing | Butyl 1148 is applied by using common drum unloaders (temperature and pressure). The exact processing conditions have to be adjust for each equipment individually and depend on the substrates and line speed too (Your equipment manufacturer will assist you). For Butyl 1148 an application temperature range from 120°C to 150°C is recommended. A longer temperature load above 160°C has to be avoided (Risk of carbonization and decomposition). |
