Room-temperature vulcanizing (RTV) silicones are well-known for their extreme durability. They are convenient one-component sealants that cure by reaction with moisture from the atmosphere.

Pressure-sensitive adhesives (PSAs) offer easy application and secure bonding, including adhering wound care dressings to skin. Skin is a variable substrate, however, and consideration must be given to various skin types to ensure dressings can be securely attached and easily removed without skin damage. 

Bonding polystyrene foam to steel and wood is an application that was traditionally done with contact cements or other solvent-based adhesives. Due to health and flammability concerns, however, the modern trend is to use 100% reactive systems.

You have a wide range of possibilities here. Normally, you would require an adhesive that has been toughened with a rubber for this.
