MG Chemicals 403C-235G, 403C Super Cold HFO-1234ZE, 235G, Aerosol, Case of 10
MG Chemicals 403C-235G Super Cold HFO-1234ZE is a non-flammable, non-conductive freeze spray for diagnosing thermally intermittent faults in electronic components. Its targeted cooling helps technicians isolate temperature-sensitive problems on PCBs, motherboards and other electronic assemblies. This listing is a case of 10 aerosols, each containing 235 g / 200 mL.
Best Uses / Applications
- Electronics repair and diagnostic benches: cool suspect components while investigating intermittent thermal faults.
- PCB rework: protect heat-sensitive components during soldering and desoldering, or rapidly cool solder joints when appropriate to the repair procedure.
- Trace inspection: help locate hairline cracks in circuit-board traces.
- Test laboratories: low-temperature testing of instruments and electromechanical devices.
- Maintenance: freeze gum and selected adhesives to assist removal after checking surface compatibility.
Key Features
- 100% HFO-1234ze formulation, as identified in the SDS.
- Non-flammable and non-conductive, as described by MG Chemicals.
- Moisture-free formulation with zero-residue performance, per the manufacturer.
- Directed application using short trigger bursts; an extension tube can be inserted when needed.
- Manufacturer describes cooling to approximately -50°C (-60°F); actual temperature depends on environmental and physical conditions.

Freeze Spray vs. Other Bench Products
| Product type | Primary purpose | Selection consideration |
|---|---|---|
| 403C freeze spray | Localized cooling and thermal fault diagnosis | Choose when cooling a specific component is the objective. |
| Gas duster | Blow away loose dust and particles | Not an interchangeable substitute for a dedicated diagnostic cooling spray. |
| Electronics cleaning solvent | Remove compatible oils, flux or other contamination | Select by contaminant and material compatibility; 403C is not a general-purpose flux remover. |
Application and Safe Handling
Read the SDS before use. Firmly hold the trigger-nozzle head, remove the security tab, insert the extension tube if needed and apply short bursts. MG Chemicals describes 403C as suitable for energized circuits; this does not remove the electrical hazards of live diagnostic work. Follow your equipment's service procedure and appropriate workplace controls.
The cold jet or liquid can cause frostbite to skin or eyes. Use with adequate ventilation: the gas can displace oxygen, and confined-space exposure or intentional inhalation can be dangerous. Keep away from heat, hot surfaces, sparks and flames. Do not pierce or burn the container, even after use. Protect from sunlight and do not expose it to temperatures above 50°C (122°F).
Frequently Asked Questions
How much is included?
This listing is for 10 aerosols. Each 403C-235G can contains 235 g / 200 mL.
What is 403C used for?
Its primary use is cooling electronic components to help locate thermally intermittent faults. Additional manufacturer-listed uses include soldering support, trace-crack investigation and low-temperature testing.
How cold does it get?
The manufacturer describes cooling to approximately -50°C (-60°F). Its TDS also lists -51°C in a feature bullet and cautions that actual results depend on environmental and physical conditions.
Is it non-flammable?
MG Chemicals describes 403C as non-flammable. The November 2025 SDS classifies it as a Category 3 aerosol with the warning that the pressurized container may burst if heated. Continue to observe all handling precautions.
Can it be used on energized circuits?
The manufacturer lists this use. Live circuit diagnosis still requires suitable training, equipment-specific procedures and electrical safety controls; non-conductive spray does not make the circuit safe to touch.
Does it leave residue or contain moisture?
MG Chemicals describes the formulation as moisture-free and zero-residue. Avoid assuming that all surfaces or environments are moisture-free after cooling.
Is it the same as a dust-removal aerosol?
No. 403C is intended for targeted cooling and thermal diagnosis, rather than primarily blowing loose debris from surfaces.
What precautions matter most?
Avoid skin and eye contact with the cold discharge, maintain ventilation, prevent exposure to heat and sunlight, and follow the SDS. Never intentionally inhale the contents.
