BIOACT EC-7R
Harmonization Code : 3208.20.90 | Paints and varnishes that are dispersed or dissolved in a non aqueous medium

Main features
- 99% USDA-Certified Biobased Cleaner
- Broad Electronics Residue Removal
- Water-Rinsable Ambient Processing
Product Description
BIOACT EC-7R is a USDA Certified Biobased Product (99%) and high-performance electronics cleaner for semi-aqueous spray and immersion defluxing. The citrus-terpene-based cleaner is water rinsable and separates from water in the rinse section, supporting solvent recovery and recycling. Used at full concentration and ambient temperature, BIOACT EC-7R removes lead-free, no-clean, RMA, and HMP flux residues, fingerprint oils, ionic contamination, and uncured SMD adhesives. It provides a Kauri-Butanol value of 95, low viscosity, high soil loading, and compatibility with commercially available immersion and spray-under-immersion cleaning equipment.
Key features
- USDA Certified Biobased Product: Certified biobased content of 99%.
- Broad defluxing performance: Removes lead-free, no-clean, RMA, and HMP flux residues.
- Ionic and process-soil removal: Removes ionic contamination, fingerprint oils, and uncured SMD adhesives.
- Ambient full-strength processing: Used without dilution for manual and immersion cleaning; heat is not recommended.
- Water rinsing and solvent separation: Separates from rinse water to support solvent recovery and recycling.
- High solvency and low viscosity: Kauri-Butanol value of 95 and viscosity of 0.8 cP.
Applications / Suitable for
- Semi-aqueous spray and immersion defluxing
- Removal of lead-free, no-clean, RMA, and HMP flux residues
- Removal of ionic contamination and fingerprint oils
- Manual cleaning and removal of uncured SMD adhesives

Cleaning and Rinse Process
Use BIOACT EC-7R at full concentration and ambient temperature. Select manual, immersion, or spray-under-immersion equipment according to the assembly, flux type, soil loading, and required rinsing and cleanliness controls.
Defluxing Sequence
Store BIOACT EC-7R in its original, sealed container above 50°F (10°C). The documented shelf life is 36 months under these conditions. Standard packages include 35 lb (16 kg) pails and 390 lb (177 kg) drums. Keep containers tightly closed in a cool, well-ventilated area away from heat, sparks, flames, and incompatible strong acids or oxidizing agents. Use appropriate ventilation and personal protective equipment and consult the current SDS for complete handling, storage, transport, and disposal requirements.
