Chemtronics DEL1692 Flux-Off Delta Flux Remover, 12oz Aerosol
Chemtronics DEL1692 Flux-Off Delta Flux Remover, 12oz Aerosol
Chemtronics DEL1692 Flux-Off Delta is a 12 oz / 340 g high-pressure aerosol flux remover for heavily encrusted and oxidized flux deposits on printed circuit boards and electronic assemblies. The manufacturer describes it as a powerful, nonflammable, fast-drying solvent that removes R, RA, RMA and synthetic fluxes, as well as oil, grease and production contaminants, then evaporates without solvent residue.
Its strong cleaning action requires careful substrate selection. It is not universally compatible with plastics, and nonflammability does not make it free of health or pressurized-container hazards. Read the applicable SDS and container label before use.
Best Uses / Applications
- Removal of stubborn flux deposits on compatible printed circuit boards and surface-mount pads.
- Cleaning chip carriers, heat sinks and metal housings or chassis.
- Cleaning compatible plugs, sockets, switches, relays and contacts after testing the complete assembly.
- Localized flushing of flux and production contaminants during bench rework.
- Hard-to-reach areas where aerosol penetration and controlled runoff are useful.
Key Features
- Extra-strength cleaning of encrusted and oxidized flux deposits.
- Removes R, RA, RMA and synthetic fluxes.
- Non-corrosive and safe for metals according to the TDS; evaluate the complete assembly separately.
- Fast evaporation with no solvent residue.
- All-Way Spray valve supports upside-down spraying.
- Manufacturer lists no ozone-depleting compounds; this does not establish general environmental or handling safety.
- 12 oz / 340 g aerosol format for localized application.

These typical physical-property values are from the September 2021 TDS. Confirm applicability to the supplied product and current process requirements. The manufacturer provides separate SDS documents for the aerosol and bulk-liquid formats; do not substitute a bulk-liquid SDS for this aerosol.
Material Compatibility
The TDS warns against use with acrylics, ABS resins, polycarbonates and polystyrenes. Its table rates ABS and polystyrene as non-compatible, and Noryl and silicone rubber as poor. Although the table rates Lexan as fair, the general warning includes polycarbonates; obtain manufacturer confirmation before use on that material rather than treating the table as approval.
Graphite, HDPE, nylon 66, cross-linked polyethylene, polypropylene, PVC and Teflon are rated excellent in the TDS; other listed materials have good or fair ratings. Always test on a non-critical area, including coatings, labels, adhesives and component materials, before cleaning the actual assembly.
Application & Safety
The TDS directs spraying from 4–6 inches away and washing parts from top to bottom so dissolved flux is carried away. Solvent evaporation alone does not remove dissolved contamination if it is allowed to dry back onto the assembly.
The linked U.S. SDS warns that the product is harmful if swallowed, causes skin and serious eye irritation, is suspected of causing cancer, and is a pressurized container that may burst if heated. It calls for reading all safety precautions before handling, protective gloves, protective clothing and eye/face protection, locked storage, protection from sunlight and a well-ventilated storage location. Follow the complete applicable SDS and label, including exposure controls and handling instructions.
Aerosol vs. Bulk-Liquid Formats
| Format | Package listed in TDS | Selection consideration |
|---|---|---|
| DEL1692 | 12 oz / 340 g aerosol | Localized high-pressure spray cleaning |
| DEL192 | 1 gal / 3.7 L liquid | Bulk-liquid process; confirm compatible equipment, current instructions and liquid SDS |
| DEL5592 | 53 gal / 200 L liquid | Larger bulk-liquid requirements; qualify process separately |
The series TDS mentions ultrasonic cleaning, but that does not authorize dispensing this pressurized aerosol into an ultrasonic or immersion bath. Select the proper liquid format and obtain manufacturer and equipment guidance for the proposed process.
Frequently Asked Questions
What is the DEL1692 package size?
DEL1692 is the 12 oz / 340 g aerosol package. DEL192 and DEL5592 are separate bulk-liquid formats.
Which flux types does it remove?
The TDS lists R, RA, RMA and synthetic fluxes, including heavily encrusted and oxidized deposits. Verify cleaning performance and compatibility on the actual assembly.
Is it safe on all plastics?
No. The manufacturer warns against several plastics, including acrylics, ABS, polycarbonates and polystyrenes. Test the complete material system and seek confirmation where its compatibility guidance is ambiguous.
Does nonflammable mean safer handling without precautions?
No. The SDS lists significant health hazards and pressurized-container hazards. Follow its exposure controls, protective-equipment, handling and storage instructions.
Can the aerosol spray upside down?
Yes. The TDS identifies an All-Way Spray valve that supports upside-down spraying. Continue to follow the container label and application precautions.
Can I use this aerosol in an ultrasonic bath?
Do not assume that a series-level ultrasonic-cleaning statement applies to aerosol dispensing. Confirm the appropriate bulk-liquid product, equipment and safety procedure with the manufacturer before using a bath process.
Does it leave residue?
The manufacturer describes the solvent as leaving no residue. Flush dissolved contamination away so flux and other soils do not redeposit as the solvent evaporates.
