Void Filler is used to displace water, inhibit corrosion, enhance adhesion, and control flow, and Denso has based it entirely on petrolatum hydrocarbons with additives to fulfill these functions. This injectable petrolatum compound is non-hardening, has excellent flexibility, is easy to pump, and is unaffected by water, acids, and salts.

Applying Void Filler is a very straightforward process. The first step is to heat this injectable petrolatum compound up to a temperature between 80 and 120 degrees Celsius. Then, the user should pump it into the lowest point until it exits the highest point in a continuous stream at about 70 degrees Celsius. It is a good idea to fill all voids completely between strands and ducts to exclude all air and water, in order to achieve the highest long-term corrosion protection.
