MG Chemicals 4354-1L, Thinner 4, 32 oz. Can, Case of 6
MG Chemicals 4354-1L, Thinner 4, 32 oz. Can, Case of 6
MG Chemicals 4354-1L Thinner 4 is a slow-drying solvent thinner for compatible MG Chemicals acrylic and urethane conformal coatings. Its slow evaporation supports leveling and gloss, while its water insolubility helps resist coating blush. This listing supplies six cans, each containing 945 mL (32 fl. oz.); the 1L catalog designation is not the actual net fill.
Manufacturer use restriction: For industrial or laboratory use only. Not for retail sale in California, Utah, Colorado and New Hampshire, as stated in the current manufacturer TDS.
Best Uses / Applications
Use 4354 for industrial electronics coating processes when the specific coating's current instructions approve Thinner 4. Its slower drying profile is useful where flow and leveling are priorities in spray application. Its solvent strength also makes it useful for oil and grease removal on compatible surfaces. Test substrate compatibility before use; it is not a universal cleaner or a substitute for every coating thinner.
Key Features
- Slow evaporation for leveling and gloss.
- Blush-resistant, water-insoluble solvent.
- Highly miscible with other common organic solvents.
- Manufacturer-described compatibility with most substrates used in electronic parts and enclosures; verify on the actual materials.
- Solvent strength for oil and grease removal.
- Case of six 945 mL cans for controlled dispensing in professional work areas.

Selection and Process Guidance
Select a thinner from the coating manufacturer's current instructions rather than choosing on drying speed alone. Add only the approved quantity, mix as directed and validate spray pattern, film thickness and finished appearance. A slower solvent can aid leveling but changes the coating process; do not transfer a dilution ratio from a different coating or thinner.
| Process need | Selection guidance |
|---|---|
| Approved acrylic or urethane coating needs slower evaporation | Consider 4354 where the coating instructions permit it; validate leveling and drying in the actual process. |
| Coating specifies a different numbered thinner | Follow that specification; Thinner 4 is not automatically interchangeable. |
| Oil and grease removal | Confirm material compatibility and workplace controls before using 4354 as a solvent cleaner. |
| Ready-to-spray aerosol coating | Follow the aerosol's own instructions; do not add liquid thinner to a pressurized can. |
Frequently Asked Questions
Does each can contain a full liter?
No. The manufacturer lists 945 mL (32 fl. oz.) net contents for 4354-1L. This listing is a case of six cans.
Which coatings can I thin with 4354?
MG Chemicals identifies it for its urethane and acrylic conformal products. Use it only where the specific coating's current instructions approve Thinner 4.
Why choose a slow-drying thinner?
Slower evaporation can support flow, leveling and gloss during application. Validate the drying time and finish within your production process.
Is 4354 water soluble?
No. The TDS lists it as insoluble in water and describes it as blush resistant.
Can it remove oil and grease?
The manufacturer describes its solvent strength as suitable for oil and grease removal. Test compatibility first and use the protective measures specified in the SDS.
What dilution ratio should I use?
There is no universal ratio for every coating. Follow the current instructions for the coating and your application equipment.
What is the shelf life?
The TDS lists five years. Keep the container tightly closed and follow manufacturer storage and safety instructions.
Is this intended for consumer retail use everywhere?
No. The manufacturer TDS states industrial or laboratory use only and not for retail sale in California, Utah, Colorado and New Hampshire.

Safety Information
Read the complete SDS before use. It identifies flammable liquid and vapor; harmful skin contact and inhalation; skin and serious eye irritation; suspected carcinogenicity; possible drowsiness or dizziness; possible hearing-organ damage through prolonged or repeated exposure; aspiration danger if swallowed; and toxicity to aquatic life. Use appropriate ventilation, protective equipment and ignition controls. Keep containers tightly closed and prevent environmental release.
