Isopropyl Alcohol IPA 99% 500ML

Ultra-High Purity 99.9% ACS Reagent Grade Isopropyl Alcohol

Engineered to meet and exceed strict American Chemical Society (ACS) specifications, this 99.9% anhydrous Reagent Grade Isopropyl Alcohol (IPA) sets the absolute industry benchmark for high-reliability electronics manufacturing, microelectronics fabrication, and precision optical maintenance. Free from denaturants, added water, and trace organic or inorganic impurities, this critical-process solvent delivers rapid, zero-residue evaporation. By maintaining an ultra-low Non-Volatile Residue (NVR) specification of under 0.001% (10 ppm), it prevents dielectric breakdown, ionic contamination, and parasitic leakage currents on high-density printed circuit board assemblies (PCBAs) and sensitive semiconductor substrates.

Superior Solvency for Polar and Non-Polar Residues

Formulated with an optimal solvency energy profile and low surface tension, this high-purity IPA effectively breaks down and dissolves a wide spectrum of polar and non-polar soils. It rapidly strips away heavy organic oils, synthetic greases, fingerprint lipids, particulate soils, uncured adhesives, and complex flux residues, including rosin (R, RMA, RA), water-soluble, and stubborn no-clean formulations. With a surface tension of 21.7 mN/m, the fluid quickly wets surfaces and penetrates ultra-low-standoff surface-mount technology (SMT) components, fine-pitch micro-BGAs, quad-flat no-leads (QFN) packages, and high-density interconnects (HDI) to flush out trapped flux activators and microscopic contaminants.

Broad Material Compatibility and Process Safety

This technical-grade anhydrous solvent exhibits outstanding material compatibility across a broad range of sensitive electronic substrates. It is safe for direct, repeated application on standard electronic-grade polymers such as FR-4, polyimide, ABS, polycarbonate, PTFE, PEEK, and polyphenylene ether, as well as delicate elastomers, synthetic rubbers, anodized aluminum, copper, and optical antireflective coatings, without inducing stress crazing, swelling, softening, or embrittlement. As a non-halogenated hydrocarbon alternative, this low-toxicity, ozone-benign solvent helps cleanrooms and ISO-certified manufacturing facilities maintain stringent environmental compliance while providing reliable chemical performance.

Multi-Industry Precision Applications and Substrate Prep

Essential for surface activation prior to critical downstream assembly processes, this solvent removes microscopic oil films to ensure maximum mechanical keying and chemical adhesion for conformal coatings, encapsulation potting compounds, underfills, and structural bonding agents. It serves as the primary cleaning standard for bare fiber optic splices, optical lenses, laser windows, magnetic read and write heads, SMT stencils, and automated fluid dispensing nozzles. For precision defluxing, benchtop rework, and heavy particulate removal, pair this solvent with lint-free technical wipes, high-density foam swabs, or ESD-safe conductive brushes.

Optimized for Ultrasonic and Critical Industrial Workflows

Due to its completely anhydrous formulation and low viscosity, this solvent excels in specialized immersion baths, ultrasonic agitation systems, and manual cold-cleaning stations. Its rapid evaporation rate accelerates line throughput in high-volume production environments by eliminating extended drying cycles and thermal baking requirements. Whether utilized in medical device manufacturing, aerospace avionics maintenance, or semiconductor wafer preparation, this ACS Reagent Grade solvent yields immaculate surface purity without leaving water spots, film lines, or ionic salts.

IPA is effective at removing oils, light greases, ink, grime, oxides, solder paste residues, adhesive residues, and flux residues. It is recommended for cleaning any of the following:

• Audio, video, magnetic, and optical heads
• Cables
• Electrical contacts and connectors
• Fiber optic connectors
• Optical equipment
• POS devices and scanners
• Precision instruments
• Printed circuit boards
• Production equipment and workstations
• Smart phones, pads, laptops, keyboards, and office equipment
• SMT stencils and screens
• Surfaces being prepared for coating application

Cleaning with IPA is often more effective when used in conjunction with the right brush, swab, or dry wipe
