RTV Expiration Date

keep it very cold in a freezer. these things are 100% solid mixed monomers that absorb a little water to crosslink and exude acetic acid and a linked polymer ensues = solid rubbery mass.

They self link with no water after a year or so. do not open them and freeze them. Last for years.

If opened the little water that came in will slowly link them, but you still extend the life at low temperatures.

Buy a newer one with a later experation date....
