Gentle on Sensitive Formulations
Paint and ink manufacturers love the QBY because it doesn’t shear their products. The gentle diaphragm action moves paint without breaking down pigments or altering viscosity.
What It Transfers
•
Automotive paints and primers
•
Printing inks and varnishes
•
Industrial coatings
•
Resins and adhesives
•
Pigment dispersions
•
Thinners and solvents
Material Recommendations
Use stainless steel for solvent-based paints. Polypropylene works for water-based coatings. PTFE diaphragms resist solvent swelling.
