MG Chemicals 402B, Super Duster 152, 285g/400g, Aerosol, Case of 10
MG Chemicals 402B, Super Duster 152, 285g/400g, Aerosol, Case of 10
MG Chemicals 402B Super Duster 152 is a pressurized HFC-152a gas duster for blowing microscopic dust, lint and loose foreign particles from surfaces. This listing offers two size variants, 402B-285G and 402B-400G, each sold as a case of 10 aerosols. Select the required size before ordering.
Important safety correction: The manufacturer's December 5, 2024 SDS classifies 402B as a Category 2 flammable aerosol (H223). Although the September 24, 2025 TDS includes conflicting “non-flammable aerosol” wording, do not treat this product as non-flammable. Keep away from heat, sparks, flames and other ignition sources. Power off electrical or electronic equipment before cleaning, hold the can upright and follow the SDS.
Best Uses / Applications
Choose 402B for general dust and lint removal in home and office maintenance, especially where a directed gas stream can reach corners that are difficult to wipe. MG Chemicals recommends 402B for home or office use over 402A, which it describes as specifically designed for electronics. Do not assume suitability for energized electronics, cleanroom use or ignition-sensitive work.

Use and Handling
Read the SDS before use. Power equipment off, remove ignition sources and use with suitable ventilation. Hold the can upright and apply short bursts, working from top to bottom to avoid redepositing dust. Use the extension tube for hard-to-reach areas. Do not invert the can: liquid discharge can cause frostbite and presents a flammability hazard. Do not intentionally inhale the contents. Protect the pressurized container from sunlight and temperatures above 50°C; do not pierce or burn it.
Frequently Asked Questions
Do you offer the 400g version?
Yes. Select the 400G variant for SKU 402B-400G. The 285G variant is SKU 402B-285G. Both are sold here as cases of 10.
Is this ordinary compressed air?
No. “Air duster” describes its function; the propellant is HFC-152a, also called 1,1-difluoroethane.
Is 402B non-flammable?
No. Follow its SDS classification as a flammable aerosol. The TDS contains conflicting wording, which must not be used to dismiss the safety precautions.
Can I clean powered electronics?
The manufacturer's application instructions say to power off electrical or electronic equipment before cleaning. Do not use the listing as authorization to spray energized equipment.
Can I spray with the can upside down?
No. Hold it upright to avoid ejecting liquid. Liquid contact can cause frostbite.
Does it leave residue?
MG Chemicals describes zero-residue performance; the TDS lists a maximum nonvolatile residue of 0.01%.
Is it suitable for food facilities?
The TDS describes use as a non-food chemical in food facilities and says recognition letters are available on request. This is not permission for food contact; confirm the applicable documentation and facility procedure before use.
How should I store it?
The TDS recommends -20 to 27°C in a dry, ventilated area away from sunlight. Observe the SDS pressure-container precautions and maximum exposure temperature of 50°C.
