  • Eco-Stencil Cleaner is fully compliant with CARB (California Air Resource Board) requirements.  Also compliant with European REACH (Registration, Evaluation, Authorization & Restriction of Chemicals) and WEEE (Waste Electrical and Electronic Equipment Directive) initiatives.  It does not contain RoHS (Restriction of Hazardous Substances) restricted substances, SVHC (Substances of Very High Concern) list substances, or halides.
Instructions: Dilution 1 Part Eco-Stencil AQ : 9 Parts DI Water - Used as directed in your batch stencil cleaner equipment instructions.  Add 9 parts deionized (DI) water to every 1 part Eco-Stencil AQ.  Mix thoroughly.  Higher concentration can be used to clean more difficult soils or the increase cleaning speed.  A common method of checking concentration is by BRIX refractive index.  For refernce, the following concentrations and readings are provided.

Chemical Properties (MSDS available upon request):
Properties based on diluted materials, as recommended for use in batch system.
Exposure Limit: Limids on components not established.  Manufacturer's recommendation 1000 ppm.
Physical State: Liquid
Odor: Clean ethereal odor
Appearance: Clear, mobile liquid
pH: 7-8
Boiling Point: 97 Degrees C (207 Degrees f)
Flashpoint and Method (TAG Closed Cup): None to boiling point
Solubility in Water: Fully miscible
Density: 1 at 25 Degrees C
VOC (by wt): 5 percent by weight (EPA)
Performance (Ultrasonic Test Method):
Stainless steel stencil coated with 5 different pastes (Kester EM907 no-clean lead-free, no-clean lead-free, H531 OA lead, FL250D no-clean lead, and Alpha Metals RMA lead RMA390) and allowed to fully dry over at least 8 hours.  Branson 5200 ultrasonic used to simulate sonics used in batch stencil cleaners.  After allotted time, samples rinsed under DI water.  if no visible flux residues or solder spheres present, the stencil is considered clean and the time logged.  Cleanliness judged with 10X visual inspection per IPC-7526 Stencil and Misprinted Board Cleaning Handbook.

Test method: Eco-Stencil AQ tested on a stainless steel stencil in Austin American Technologies X30A Stencil Cleaner using 4 different pastes (Kester EM907 no-clean lead-free, no-clean lead-free, H531 OA lead, and FL250 no-clean lead).  Cleanliness
judged with 10X visual inspection per IPC-7526 Stencil and Misprinted Board Cleaning Handbook.
The following were the results:
1. Paste was removed from stencil in less than 1 minute into the cleaning cycle.
2. Foaming was minimal even after a 20 minute cycle.
The goal of compatibility testing is to test until the point of failure.  Test parameters are generally extreme and accelerated, so go beyond the real world environment.  Techspray considers Eco-Stencil AW compatible within normal operating conditions of batch stencil cleaning and with exposed materials normally found in the equipment and stencils.
