How To Clean Pumpprint from Adhesives
How To Clean Pumpprint from Adhesives
WHAT IS THE CUSTOMER‘S STORY?

The customer used water-based cleaning agent from our competitor, which did not clean the pumpprints properly, so the adhesive got cured in the apertures (holes), which has caused printing errors. Moreover, the pummprint got devalued after some time and the cleaning system got clogged because of the cured adhesive as well.

WHAT WE TESTED?

We tested the cleaning of uncured one-component epoxy adhesive from pumpprints.

Type of Adhesive: Three Bond 2217H

Adhesive Solubility Test

The adhesive solubility test method determines which solvent can dissolve the adhesive without damaging the original object. Testing can be used to see how the adhesive reacts with different materials and solvents. This is crucial for applications where damage to the substrate could occur.

RESULTS OF TESTING
Success rate: 100%

The customer was pleased about Proton® 69 and its results as the adhesive dissolved completely and in a very short time. The reason is quite simple, adhesives get cured in water, so water-based cleaning fluids are ineffective. Proton® 69 is an alcohol-based cleaning agent with high efficiency.

The second positive effect is that we prolonged the life of the cleaning system, especially of the nozzles and pumps, which are not polluted by cured adhesive anymore. The customer has been using ours cleaning chemistry since the testing.
