Kester 135 Soldering Flux Non-Activated Rosin

Kester 135 Soldering Flux (Non-Activated Rosin Flux) is an amber-colored, homogeneous solution composed of pure water-white rosin dissolved in a suitable solvent. Manufactured by Kester, this specialized solvent formulation exhibits non-corrosive and non-conductive properties identical to those of pure rosin itself, ensuring high reliability in electronic assembly.

Technical Features of Kester 135 Soldering Flux

To deliver consistent quality, Kester 135 is carefully processed to eliminate foreign particles commonly found in natural rosin. Under the former MIL-F-14256 specification, this non-activated rosin flux earned Qualified Products List (QPL) approval as Type R.

Due to its optimized solids content and the low surface tension of its high-purity alcohol solvent, the flux offers enhanced mobility across circuit surfaces. This high-grade solvent formulation makes the flux exceptionally reliable for critical solderability testing applications.

Key Product Highlights

• High Purity: Thoroughly processed to remove natural rosin contaminants.
• Non-Corrosive Properties: Solvent system matches the non-conductive and non-corrosive nature of rosin.
• Enhanced Mobility: Low surface tension alcohol solvent allows fluid movement.
• Testing Reliability: High-grade solvent ensures reliable performance in solderability testing.
