Loctite Primers and Activators: Frequently Asked Questions

Q1: Do you need primer for Loctite adhesives?

A: In many cases, Loctite primers are recommended—especially when bonding inactive metals like stainless steel or anodised surfaces. Primers help improve cure reliability and bond strength. However, some Loctite products are formulated to work without a primer on active surfaces.

Q2: What is the purpose of Loctite activators?

A: Loctite activators are used to speed up the curing process of anaerobic adhesives. They are ideal for applications that require a fast fixture time or when bonding non-reactive surfaces like plated or anodised metals.

Q3: How do Loctite primers improve adhesive performance?

A: Loctite primers enhance surface energy, promote chemical adhesion, and ensure faster and more consistent curing—particularly useful when bonding low-energy or inactive substrates.
