APPLICATION: For fastening together numerous types of material or to be fastened into pre-tapped holes. Widely used in many engineering applications. Zinc coatings prevent oxidation of the protected metal to create a longer lasting finish. It does this by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust that (in contrast to iron oxide) does not trigger a breakdown of the substrates surface integrity ForgeFix A04 B2052
