Dental Water-washableResin
RP-405-TW01W
- RP-405-TW01W is a water-washable resin that only requires rinsing with water to remove excess resin from the surface.
- Elongation at break of 14–15% with high impact strength — tough, durable printed parts.
Material Features
Rinse with Water Only
RP-405-TW01W is a water-washable resin that only requires rinsing with water to remove excess resin from the surface — no alcohol baths, no solvent handling, and a safer, lower-cost post-processing workflow.
High Toughness & Elongation
Elongation at break of 14–15% and notched impact strength of 34–52 J/m give printed parts excellent flexibility and impact resistance — models withstand handling, film pressing and daily use without cracking.
Low Viscosity, Smooth Layers
A viscosity of only 90 ± 50 cps at 25 °C lets the resin flow and recoat quickly, forming smooth, even layers that reproduce crisp occlusal detail on every print.

Applications
Orthodontic Dental Models
High-precision orthodontic models printed with RP-405-TW01W water-washable resin. After printing, a simple water rinse removes excess resin from the surface — no alcohol or solvents — leaving clean, smooth models ready for aligner manufacturing, treatment simulation and appliance design.
- Water rinse removes excess resin — no alcohol or solvents needed
- High elongation and impact resistance for durable working models
- Crisp occlusal detail for accurate aligner fitting
