Colophony – Ideal properties for demanding applications

Colophony is characterized by unique properties that translate into its versatility and effectiveness across a wide range of applications. Its solubility in toluene is just 0.05%. The softening temperature reaches a minimum of 78°C, making the product resistant to the high temperatures encountered during soldering. An acid number ranging from 160-190 mg KOH/g and low ash content ensure purity and chemical stability. These factors are crucial for maintaining the quality of connections. Colophony is used as a base for standard flux, where it constitutes a 25% solution in isopropyl alcohol.
