Permabond ASC10 Anaerobic Surface Conditioner & Accelerator for Threadlockers

Product Name

Permabond ASC10 Anaerobic Surface Conditioner & Accelerator for Threadlockers

Brief Description

Permabond ASC10 is a rapid-drying anaerobic activator designed to significantly accelerate the cure of anaerobic adhesives and sealants. It is particularly effective on inactive or passive materials such as stainless steel, aluminum, zinc plating, cadmium plating, glass, and painted surfaces. This product also enhances adhesive performance on difficult-to-bond materials, speeds up curing in cold-temperature environments, and improves bonding on poorly mated parts or those with larger gaps. Additionally, it serves as a surface cleaner, helping to remove contaminants for better adhesion.

Popular Applications & Uses

• Pre-treatment for anaerobic threadlockers, retainers, and sealants.
• Improving adhesion on passive metals (e.g., stainless steel, aluminum, zinc, cadmium).
• Accelerating cure speed in cold-temperature environments.
• Enhancing bonding on poorly mated parts or large gaps.
• Locking screws and studs.
• Retaining bearings and shafts.
• Sealing threaded pipe.
• Making form-in-place gaskets.
• Surface cleaning and preparation.

Special and Unique Features

• Rapid drying formula for efficient production and assembly.
• Enables cure to take place on passive surfaces.
• Faster curing in cold conditions.
• Improves cure on poorly mated parts.
• Helps remove contaminants from surfaces.
• Leaves a thin initiator film on treated surfaces, allowing bonding up to 30 days after application.
• Contains a non-halogenated solvent formula, making it environmentally friendly and free of ozone-depleting agents.
• MIL-SPEC Compliant: Meets MIL-S-22473E (Grades N & T) and MIL-S-46163A (Type N & T) for military and industrial applications.

Surface Compatibility

Permabond ASC10 is designed for use primarily on inactive or passive surfaces. These include, but are not limited to: stainless steel, aluminum, zinc plating, cadmium plating, gold, glass, plastic, and painted surfaces. It can also be used to increase the cure rate on less active substrates such as aluminum.

Known backups / known substitutes

• Loctite® 7649
• 3M™ Scotch-Weld™ AC09
• Permatex® Surface Prep Activator for Anaerobic
• Loctite SF 7471
• Permabond A905 (similar product, more widely available in Europe)

Comparison Note

Permabond ASC10 offers a high-performance solution for enhancing anaerobic adhesive reliability and significantly reducing cure time, serving as a direct alternative to products like Loctite® 7649 and 3M™ Scotch-Weld™ AC09. It is specifically formulated to activate inactive surfaces and to speed up the cure process, or to increase the maximum gap through which anaerobic adhesives and sealants can effectively cure.
