Product Name
LOCTITE 7360 ADHESIVE REMOVER CLEANER (25658)
Brief Description
LOCTITE SF 7360 is a non-CFC, low-odor, solvent-based formulation specifically engineered for the efficient removal of uncured adhesive and adhesive residues. It is an aliphatic ester blend cleaner primarily utilized in the PCB (Printed Circuit Board) assembly industry.
Popular Applications & Uses
- Cleaning of stencils, screens, and dispensing nozzles used for applying surface mount adhesives.
- Removal of uncured adhesives from misprinted circuit boards.
- Dissolving and removing uncured epoxy adhesives and their residues.
Industries that Commonly Use It
- LED/Electronics: Primarily used in the PCB assembly industry for cleaning and maintenance of electronic components and equipment.
- Chemical Industry: As a specialized solvent cleaner, it is a product of and used within the broader chemical industry.
- General Manufacturing: Applicable in manufacturing processes involving adhesive application and cleanup, particularly in precision assembly.
- Distributers & Resellers: Companies that supply industrial maintenance, repair, and operations (MRO) products to end-users.
Special and Unique Features
- Non-CFC Formulation: Environmentally conscious, as it does not contain ozone-depleting chlorofluorocarbons.
- Low Odor: Provides a more comfortable working environment compared to high-odor solvents.
- Epoxy Compatibility: Fully compatible with epoxy adhesives, ensuring it will not cause hardening during soaking, which is crucial for effective cleaning.
- Solder Resist Compatibility: Compatible with commonly used solder resists, preventing damage to circuit board components.
- Low Volatility: Ideal for use in open reservoirs, though it requires drying by cloth or compressed air.

Known backups / known substitutes
While direct, specialized substitutes for LOCTITE 7360 are typically other industrial-grade solvent cleaners for electronics, general adhesive removers and cleaning agents can serve as backups for less critical applications or different adhesive types. These may include:
- Other specialized solvent cleaners for uncured epoxy adhesives in electronics assembly.
- Isopropyl alcohol (rubbing alcohol) for general adhesive residue removal on some metals.
- Acetone (found in nail polish removers) for adhesive residue on glass.
- Commercial stain removers for fabric.
- General surface prep cleaners.
Comparison Note
LOCTITE 7360 stands out as a specialized, non-CFC, low-odor solvent cleaner formulated specifically for the delicate and precise requirements of the PCB assembly industry. Unlike general-purpose cleaners or mechanical removal methods, it is designed to effectively remove uncured epoxy adhesives and residues from sensitive components like stencils, screens, nozzles, and circuit boards without causing hardening of the adhesive during soaking or damaging compatible solder resists. Its specific chemical composition (aliphatic ester blend) ensures optimal performance for its intended applications, providing a clean surface essential for proper adhesive bonding and cure in electronic manufacturing.
