QX-5 Red Emulsion | Fast Exposing
QX-5 Red is a universal, ready-to-use, fast-exposing SBQ-photopolymer direct emulsion. Its relatively high viscosity (5000 cps) and solids content (41%) result in better mesh bridging on coarse mesh, and fast drying.
Features-At-a-Glance:
- Fast exposing
- Fast stencil throughput for high volume shops
- Dependable polymerization assures durability and ink resistance
- High (41%) solids content
- Dries quickly
- Better mesh bridging on coarse mesh
- Lower Rz value yields sharper printed edges
- High viscosity (5000 CPS)
- Easier to control during coating
- Solvent Resistant - Resists a wide range of solvent-based inks
- Moisture Resistant - Will not become tacky under high humidity conditions
- Red color - Easy stencil inspection, even on colored mesh
- Shelf life - unopened: 1 year at 70º F. (21º C.)
