The 824 Isopropyl Alcohol (IPA) liquid is a high purity(99.9%), multipurpose cleaner and solvent. The purity level meets Grade A standard for MIL Spec TT-I-735A and ASTM D770, ensuring that no contamination occurs from its use.

As a cleaner, it is fully miscible in water and most organic fluids, making it good at dissolving dirt, light organic contaminants, and ionic flux residues. Since the 824 is highly anhydrous (without water) and hygroscopic (absorbs humidity), it readily scavenges water off surfaces, trapping the water in the IPA solution as an azeotropic mixture. This helps to dehumidify surfaces.

As a solvent, it acts as a moderate evaporation, ‘plastic safe’ diluent (see compatibility chart) and is used to improve the properties of paint resins and other heterogeneous solid mixtures. Therefore, it serves as a useful carrier solvent to adjust the rheological properties and compatibilities of complex mixtures. Due to IPA’s volatility, it resists entrapment in the coating. As it dries, it gives off a very light odor, which is not bothersome but serves as a cue to limit over-exposure due to poor ventilation.

Applications & Usages

Since the 824 is safe for most plastics, seals, ceramics, and printed circuit board components, it is used heavily in the electronics industry. It is great for cleaning screens, stencils, fiber optics, cables, keypads, printed circuit board components, or electrical contacts and connectors. It is also used to clean oxides and grime on audio or video tape heads. It effectively removes light greases, oils, and flux without adding additional residues to contacts, relays, and circuit boards connectors. It is quick drying relative to water. Further, it can be used to wash off more aggressive organic solvents like acetone or toluene.

Plastic safe can be used in all of these applications.
