ASM DEK 431093 Pro Understencil Cleaner, 20 Liter, Case of 1
ASM DEK 431093 Pro Understencil Cleaner, 20 Liter, Case of 1
ASM DEK 431093 is the 20-liter DEK Pro cleaning agent for SMT stencil-printing processes. The manufacturer identifies it for understencil cleaning on vacuum and non-vacuum printers, as well as manual cleaning. This listing supplies one 20-liter container, suited to production teams purchasing cleaning chemistry in a larger format.
DEK Pro is designed to improve print-process performance without affecting the thixotropic properties of solder paste. ASMPT describes the chemistry as residue-free after evaporation and formulated to reduce the risk of solder slump and solder balling. Part 431093 is standard DEK Pro, not DEK Pro XF.
Best Uses / Applications
- Automated understencil cleaning in SMT solder-paste printing operations using compatible vacuum printers.
- Understencil cleaning on compatible non-vacuum stencil printers.
- Manual stencil-cleaning tasks permitted by the equipment and chemistry instructions.
- Electronics assembly facilities selecting a 20-liter supply format for their approved stencil-cleaning process.
Key Features
- Purpose-designed DEK Pro understencil cleaning chemistry.
- Manufacturer-listed suitability for vacuum and non-vacuum printers and manual cleaning.
- Designed not to affect solder-paste thixotropic properties.
- Residue-free after evaporation, according to ASMPT's product brochure.
- Manufacturer states compatibility with solder-paste materials; validate the complete process with your specific paste, stencil, and printer.
- 67°C flash point, verified in the manufacturer's US safety data sheet.

Frequently Asked Questions
What is included with part 431093?
This listing is for one 20-liter container of standard DEK Pro understencil cleaning agent. The store SKU is 431093; ASMPT's brochure also identifies SAP reference 03130223.
Can it be used with a non-vacuum stencil printer?
Yes. ASMPT's English product brochure lists standard DEK Pro for vacuum and non-vacuum printers and manual cleaning. Confirm compatibility and operating settings for your particular equipment before use.
Is this the same as DEK Pro XF?
No. Part 431093 is DEK Pro. DEK Pro XF is a distinct formulation with different part numbers and flash-point characteristics. The English brochure lists XF for vacuum printers.
Does DEK Pro leave residue or change solder-paste properties?
ASMPT describes DEK Pro as residue-free after evaporation and states that it does not affect the thixotropic properties of solder paste. Establish the appropriate cleaning cycle and drying conditions through your process validation.
Does the 67°C flash point mean no safety precautions are needed?
No. A flash-point value is not a blanket safety classification. Follow the current safety data sheet and facility procedures for ventilation, protective equipment, handling, storage, and disposal.
Can DEK Pro be used for manual stencil cleaning?
Manual cleaning is among the manufacturer's listed applications for standard DEK Pro. Follow the equipment instructions and current product documentation; do not infer dilution ratios, dwell times, or cleaning-cycle settings from this listing.
