SPS -2280 adhesive is an adhesive used for composite extrusion/injection molding of thermoplastic elastomers (such as TPV, TPE) and metals (steel strips, aluminum strips), and has good adhesion to thermoplastic elastomers and metals.
1. The method of use is as follows:
- Shake the glue bucket before use Evenly and ready to use. It can also be used after dilution, the maximum dilution should not exceed 300%.
- Metal (such as steel strip, aluminum strip ) The surface should be degreased and derusted first to ensure that it is clean and oil-free, then apply shaken glue, cure at 200±10°C for 30-15 seconds, and then enter the extruder head for compound extrusion and self-curing. Increasing the curing temperature can shorten the curing time, and the residence time at temperatures above 300°C should not exceed 5 seconds.
- There must be enough The pressure makes the TPV and the metal belt tightly combined.
- Thinner formula: toluene can be used as thinner.
- Storage conditions and expiration date: Store at room temperature, The shelf life is 12 months. If possible, it is best to store in a dry environment at 5-30°C.
- SPS-2280 glue is solvent-based glue , need to be stored, transported and used as dangerous goods.
