How Loctite 574 Works and Where It Excels

Loctite 574 is a dimethacrylate ester anaerobic adhesive sealant in an orange paste format. It cures between mated rigid metal flanges in the absence of air remaining stable on the surface until the joint is assembled and metal contact activates the anaerobic cure. This gives assemblers adequate open time to position components correctly before the cure begins. With a thixotropic viscosity of 70,000–120,000 mPa·s, it stays where it's applied. A 0.25 mm gap tolerance makes it suitable for machined gearbox and engine casing flanges. Importantly, after assembly it provides an immediate low-pressure seal a useful feature when systems need to be tested quickly before full cure is achieved. Loctite 574 is approved for manual bead application, rolled film, and screen printing supporting everything from field maintenance to high-volume automated production lines.

Strength, Sealing, and Chemical Resistance

After 24 hours at 22°C, Loctite 574 delivers a lap shear strength of 8.5 N/mm² on grit-blasted steel and a compressive shear strength of ≥6.0 N/mm². Tensile strength on steel is 5 N/mm². These are solid performance numbers for a flexible anaerobic gasket sealant used in medium-pressure flange applications. Chemical resistance is strong where it counts most: motor oil at 125°C shows 100% strength retention after 1000 hours, water/glycol mixture at 87°C holds at 85%, and heat aging is stable at 120°C over the same duration. For gasoline exposure, retention is 75% adequate for most automotive and general industrial applications. UV fluorescence allows post-assembly verification of sealant coverage, and the cure can be accelerated using SF 7471 or SF 7649 activator when rapid production demands it.
