Disposable cartridge packaging is another convenient option offered by Master Bond. This form of packaging is most suitable for use with multi component polymer systems such as epoxies, silicones, polysulfides. Pre-measured ratio sensitive compounds are contained in separate compartments within the Semkit® cartridge. This assures proper storage and when ready to use mixing is performed consistently, uniformly in accurate proportions. Material contained within the Semkit® is mixed within the transparent plastic high/low density polyethylene cartridge, eliminating waste and labor intensive tasks such as measuring. In addition to increasing productivity Semkits® enhance quality by avoiding air entrapment and product contamination which can occur when employing other packaging methods. Since the product is applied directly from the Semkit® package, skin contact at the work station is minimized.
Both foil barrier and injection style Semkits® are available for use. Injection kits are primarily used when the mix ratio is 100 to 1 or greater. They are able to handle a wide range of viscosities. Kits can be mixed/applied manually, semi-automatically or automatically. Packaging sizes are typically from 1 ounce to 20 ounce units. They have been found to be quite cost effective in benchtop and assembly applications. After mixing it is important to note that the nozzle and kit are disposable.
