MG Chemicals 435-1L Thinner, 32oz Can, Case of 6
MG Chemicals 435-1L Thinner, 32oz Can, Case of 6
MG Chemicals 435-1L is a super-fast-drying, low-VOC thinner for compatible MG Chemicals conformal coatings and EMI/RFI shielding paints. Its fast evaporation makes it useful for spray processes requiring quick drying, while the formulation is designed to promote adhesion to plastic substrates. This listing supplies a case of six cans.
Package-size clarification: The manufacturer specifies 945 mL (approximately 31.9 US fl oz) per can, despite the 435-1L part number. The existing 32 oz product title is retained; do not interpret the part number as a full 1,000 mL fill.
Best Uses / Applications
- Thinning compatible conformal coatings for spray application.
- Viscosity adjustment of compatible EMI/RFI shielding paints.
- Electronics coating processes requiring fast solvent evaporation.
- Industrial and laboratory coating work involving suitable plastic substrates.
Use only where the coating's own technical data sheet specifies compatibility. Select dilution ratios from that coating's instructions; there is no universal mixing ratio for every coating or application method.
Key Features
- Super-fast drying and fast evaporation.
- Low calculated VOC, as reported by the manufacturer.
- Designed to enhance adhesion to plastic substrates.
- Highly miscible with other common organic solvents.
- Compatible with most substrates used in electronic parts and enclosures, subject to material testing.

Thinner Selection Comparison
| Option | Selection consideration |
|---|---|
| 435 | Super-fast drying; manufacturer highlights spray applications needing fast evaporation and low VOC. |
| 4352 Thinner 2 | Manufacturer describes moderately fast drying, blush resistance, leveling and gloss. Verify suitability with the exact coating. |
| Coating-specific dilution instructions | Control thinner choice, ratio and process settings. Do not substitute solely because another thinner is in the same brand family. |
Application and Material Compatibility
Check the exact coating's technical instructions before mixing. Validate dilution and spray settings on a test piece, and test the thinner on the intended plastic, finish or assembly before broader use. Compatibility with many electronics substrates is not a guarantee for every plastic or coating. Do not assume dip or brush suitability from the thinner name alone.
Safety, Storage and Manufacturer Use Notice
Manufacturer notice: For industrial or laboratory use only. The manufacturer TDS states: “Not for retail sale in California, Utah, Colorado and New Hampshire.” The existing listing also specifies industrial use only in Canada and states with similar VOC regulations. These are manufacturer/listing notices, not a determination that a particular transaction is permitted.
Highly flammable liquid and vapor. The SDS also identifies serious eye irritation and possible drowsiness or dizziness. Keep away from heat, sparks, flames and other ignition sources. Avoid breathing mist, vapor or spray; use only outdoors or in a well-ventilated area with appropriate gloves, protective clothing and eye protection. Follow SDS grounding, bonding and static-discharge precautions. Store cool, in a dry, well-ventilated area away from sunlight, and keep secured as directed in the SDS.
Frequently Asked Questions
Is 435-1L a full liter?
No. The manufacturer packaging table specifies 945 mL per can. The part number contains “1L,” while the existing title rounds the package to 32 oz.
How many cans are included?
This listing supplies a case of six 945 mL cans.
What is it used to thin?
It is intended for compatible MG Chemicals conformal coatings and EMI/RFI shielding paints. Confirm the exact coating's recommended thinner before use.
What dilution ratio should I use?
Use the ratio specified by the particular coating's TDS and your validated application process. A universal ratio is not specified here.
Is it safe on every plastic?
No blanket compatibility claim should be assumed. The manufacturer says it is compatible with most substrates used in electronic parts and enclosures; test the actual material first.
Does low VOC mean nonflammable?
No. The TDS lists a −17°C flash point, and the SDS classifies it as a highly flammable liquid and vapor.
Why choose 435 rather than a slower thinner?
Its super-fast evaporation suits compatible spray processes requiring quick drying. Other evaporation profiles may be more suitable for different coatings and methods.
What is its shelf life?
The TDS lists five years. Follow the SDS and manufacturer storage instructions.
