Denso Void Filler is a petrolatum compound specially formulated for hot injection into voids. The compound is based entirely on petroleum hydrocarbons with additives to displace water, inhibit corrosion, enhance adhesion and control flow.

Uses

Denso Void Filler is pumped into the voids occurring between pipes, cables, ducts and protective sleeves to exclude air and water. It is generally pumped warm and sets to a semi-solid paste to provide corrosion protection of the steel.

Features

• Non-hardening
• Excellent flexibility
• Penetrates and wets existing corrosion
• Can be pumped
• Unaffected by water, acids orsalts
• Can be supplied in large quantities

Application

The void filler is heated between 176°F to 248°F (80°C to 120°C) and pumped into the lowest point until it exits the highest point in a continuous stream at about 158°F (70°C). For full long-term corrosion protection, it is essential to completely fill all voids between strands and ducts to exclude all air and water. Designs shall allow for expansion and contraction due to temperature change without creating pressure in the ducts.
