Dimensional changes may occur MelaTech in foam dependant on the relative humidity of the surrounding air. Allowances should therefore be made to overall sizes based on the anticipated moisture content of the MelaTech when in-situ.

Permanence
MelaTech is resistant to hydrolysis, alcohols, hydrocarbons, most organic solvents and dilute acids and bases.
