To use PlatSil® SiliFoam, first, make sure you've got all the parts of the two - part kit. Mix them well following the instructions. You can use it for various projects, especially when making prosthetic appliances with PlatSil® Gel Silicone Rubber. Just back - fill the surface layers of the gel with this foam to reduce the weight. When handling the foam, wear appropriate protective gear as per the safety data sheet. Store it in a cool, dry place to keep it in good condition. If you notice any strange changes in the foam's appearance or texture, don't use it and check the technical bulletin for guidance.
