I am currently engaged in a local project that requires a unique attachment solution. We need to securely affix a 100g object, coated with cross-linked polyethylene foam, to a board that is covered in synthetic fur. The attachment must be robust enough to endure shaking and bumps. Importantly, it should also be biodegradable, allowing the object to detach naturally after a period of 2-3 days. Any insights or suggestions on materials and methods that could facilitate this requirement would be greatly appreciated. Thank you for your expertise and assistance!
