ZINC BASE TOOL JOINT COMPOUND
ZN40 Tool Joint Compound is manufactured with the finest powdered metallic zinc and a high temperature, extreme pressure, petroleum base composition. The zinc used in the manufacture of ZN40 meets API and IADC requirements. ZN40 reduces plating and buildup of zinc, a problem encountered with other zinc products. This product conforms to the recommendation of “Tool Pushers Manual” (IADC-International Association of Drilling Contractors), Section B-2, Pages 1 and 2, and API (American Petroleum Institute) RP 5A3/ISO 13678. ZN40 contains less than 0.3% sulfur as recommended by tool joint manufacturers. ZN40 has good brushability over a wide range of temperatures, is resistant to water washout, has good adhesion to surfaces, and prevents against rust and corrosion.
