Chem-Crest 905
Free Rinsing
Mildly Acidic
Liquid Detergent Concentrate for Aqueous Displacement
Chem-Crest 905 is an aqueous displacement solution capable of displacing and dispersing various hydrophobic films produced by oils, organic solvents or lubricants on its own, or where a non-halogenated solvent is used first to remove heavy contaminants (dual process, patented). It is capable of producing hydrophilic surfaces upon rinsing with water, is free rinsing, and also removes various machining oil residues, fingerprints, and particulates. Chem-Crest 905 is often combined with Chem-Crest 715 to increase detergency for highly contaminated substrates.
Chem-Crest 905 is effective on light to medium oils, greases, carbon residues, particulate matter, fingerprints, and electrolytic fluids, as well as many other contaminants.
Chem-Crest 905 is compatible with various plastics and metallic surfaces such as stainless steel, aluminum, and brass — when used as directed.
Operating Conditions:
Chem-Crest 905 is typically used at 4–8% by volume. Typical operating temperatures: 120–150°F. Chem-Crest 905 is easy to rinse and leaves no residues when ultrasonically rinsed with deionized water. The ultrasonic frequency of the rinses is recommended to be 40 kHz or 132 kHz, dependent on the material makeup of the substrate, and the contaminants being removed. Contact your Crest representative for product-line specific recommendations.
