| Method Of Use | In general a good adhesion without a primer on polyester, polystyrene foam, polyurethane foam, plaster and plywood. On metal sheets, an excellent adhesion is achieved by roughening and degreasing with acetone. For lacquered and coated surfaces we advise to remove the layers by roughening and degreasing with acetone. For detailed information about these applications, please consult Bostik.
Application conditions: Application temperature between +15ºC and +25ºC and a relative humidity between 40% and 60%. Substrate: The substrate should be dry, clean and free of dust and grease. Smooth non porous materials, such as metals, should be roughened and degreased. Application method: Machine, spatula, roller, calender roll. Pot life C20°C/55%R.H.: 100 minutes. The pot life depends on the amount of product, the temperature and the relative humidity. The indicated pot life is measured with 100 g mixed product at a temperature of 20°C and a relative humidity of 55%. Application: The mixture has to be applied within 100 minutes. Apply Marocol 18576 one side (on strong porous surfaces two sides). Open time 20°C/55% R.H.: 110 minutes. The open time depends on temperature and the relative humidity. The open time is measured after mixing at a consumption of 200 - 400 g/m², a temperature of 20°C and a relative humidity of 55%. Assembling: After applying the adhesive, assemble the parts (within the open time) and immediately clamp or press (0.1 - 1 kg/cm²). Pressing time: ca. 8 hours at 20°C. The pressing time depends on temperature and relative humidity. The pressing time is measured at a consumption of 200 - 400 g/m², a temperature of 20°C and a relative humidity of 55%. Curing time: Complete curing will take about 24 hours at a temperature of 20°C and a relative humidity of 55%. Depending on higher or lower temperatures the curing time will be shorter or longer. Consumption: 200 - 400 g/m² (depends on type of substrate and on the expected differences in thermal expansion). Cleaning: Uncured Marocol 18576 can be removed with Solvent 5 or acetone. |
