Techspray 1610-G4 Technical Grade 99.8% Isopropyl Alcohol | 1-Gallon Bottles
Techspray 1610-G4 — Technical Grade 99.8% Isopropyl Alcohol | 1-Gallon | Electronics Cleaning & Flux Thinning
Techspray 1610-G4 is a technical-grade 99.8% pure anhydrous isopropyl alcohol (IPA) formulated specifically for electronics cleaning, defluxing, stencil cleaning, tape head cleaning, and flux thinning. At 99.8% purity, it contains the minimum possible water content, enabling fast evaporation and eliminating the risk of water-induced oxidation on sensitive PCB assemblies and components. Plastic-safe and non-ozone depleting.
Don’t compromise with bargain-grade alcohols for critical electronics work. Lower-purity IPA contains significantly more water, which slows drying, leaves residue, and can cause oxidation on solder joints and metal contacts. Techspray 1610-G4 delivers the consistent purity that electronics manufacturing demands.

Key Features
- 99.8% anhydrous IPA — minimum water content — fast evaporation with no water residue; eliminates the risk of oxidation on solder joints, PCB traces, and metal contacts that lower-purity alcohols can cause
- Ideal for electronics cleaning and defluxing — removes flux residues, ionic contaminants, light oils, and assembly residues from PCBs, connectors, and electronic assemblies
- Excellent flux thinner — compatible with most rosin and no-clean fluxes for viscosity adjustment in wave soldering, selective soldering, and hand soldering applications
- Stencil and screen cleaning — effective for under-stencil wiper systems and manual stencil cleaning to remove solder paste before it dries
- Plastic-safe formula — safe for use on most plastics, making it suitable for cleaning connectors, housings, and PCBs with plastic components
- Non-ozone depleting — environmentally compliant; meets requirements for use in facilities with ozone-depleting substance restrictions
Industries & Applications
- Electronics manufacturing — post-solder flux removal, PCB defluxing, and general board cleaning in SMT and through-hole assembly lines
- Stencil printing — manual and automated stencil cleaning to remove solder paste and maintain print quality
- Rework and repair — cleaning solder residues and flux after hand rework, BGA reballing, and component replacement
- Tape head and contact cleaning — cleaning precision tape heads, connectors, relay contacts, and switches
- Laboratory and R&D — general-purpose cleaning solvent for electronics prototyping and test equipment maintenance
- Field service — portable cleaning of electronic assemblies and contacts in the field

Frequently Asked Questions
Why use 99.8% IPA instead of 70% or 91% isopropyl alcohol for electronics?
Lower-purity alcohols (70%, 91%) contain significantly more water as the remaining volume. Water slows evaporation, leaves residue, and can cause oxidation on solder joints, PCB copper traces, and metal contacts. For electronics cleaning where fast, residue-free evaporation is critical, 99.8% technical-grade IPA is the correct choice. The small cost premium of high-purity IPA is negligible compared to the risk of board damage or field failures from water contamination.
Can Techspray 1610-G4 be used to thin solder paste flux?
Yes — 99.8% IPA is widely used as a flux thinner for rosin and no-clean fluxes in wave soldering, selective soldering, and hand soldering applications. Always consult your flux manufacturer’s documentation for recommended thinner ratios and compatibility before adjusting flux viscosity.
Is Techspray 1610-G4 safe for use on plastics?
Yes — Techspray 1610-G4 is formulated to be plastic-safe for most common engineering plastics used in PCBs, connectors, and electronic housings. For sensitive or unusual plastics, test on an inconspicuous area first before full application.
How does Techspray 1610-G4 compare to aerosol IPA products?
The 1610-G4 1-gallon bottle format is designed for bulk use — refilling spray bottles, ultrasonic cleaning baths, stencil wiper systems, and high-volume cleaning processes. Aerosol IPA products are better suited for spot cleaning and field service. The gallon format offers significantly lower cost per ounce for production environments.
What is the shelf life of Techspray 1610-G4 IPA?
IPA has a long shelf life when stored properly in a tightly sealed container away from heat, ignition sources, and direct sunlight. Refer to the Techspray SDS for specific storage requirements and shelf life information. Once opened, keep the container tightly closed to minimize evaporation and water absorption from ambient humidity.
