Loctite Primers, Activators and Surface Preparation

Loctite primers, cleaners, and degreasers are highly effective and are available in both water-based and solvent-based formulations. When choosing a cleaner, degreaser, or primer, the major factors to consider are drying time, residue, odour, and substrate compatibility. Residue is a particularly important concern: if there is any secondary processing of the part, such as painting or bonding, a residue could interfere with that process. Browse their full range below.

Types of Loctite Primers and Activators

Loctite primers and activators are designed to optimise the performance of adhesives by enhancing surface preparation and curing. Loctite primers are ideal for preparing inactive metals, plastics, and other difficult-to-bond surfaces. These primers improve bond strength and adhesion reliability. Loctite activators, on the other hand, are used to accelerate curing times of adhesives—especially in applications where a fast fixture time is required or ambient curing is insufficient. Choosing the right primer or activator depends on your substrate material, bonding speed requirements, and specific application conditions.

Brochure Spotlight

loctite cleaners brochure

Find the right cleaner or Loctite primer for your application.

Degreasers and parts cleaners are available for removing metal filings, oil, grease and other contaminants from components, while hand cleaners should be used for removing dirt, grease, grime, oil and adhesive residues from hands.

Substrate compatibility is a common concern when dealing with plastics and solvent-based cleaners, especially when using Loctite primers for bonding or adhesive applications.

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.
