Water Washable Dental Model Resin
Key Features
RF-ZJ-02 is a water washable photosensitive resin with low odor, low shrinkage, strong tensile and flexural performance, and good toughness. Printed models can be cleaned with tap water instead of alcohol, shortening post-processing time while delivering fast forming, high precision, and strong detail reproduction for dental model production.

Post-Processing & Storage
-
1
Wash – Wash residual surface resin with water first, then clean with water or IPA in an ultrasonic cleaner. Avoid high-frequency shock or forceful scrubbing to protect fine surface details.
-
2
Dry – Thoroughly blow the model dry with a hair dryer, air gun, or similar tool.
-
3
Remove Supports – Remove supports before post-curing. Removing them after curing can easily damage the support contact surface.
-
4
Post-Cure – For applications requiring certain toughness, UV cure for about 5 minutes. Store printed parts in a cool, dry place after curing.
Storage
Store below 25°C in a cool place away from direct sunlight. Keep away from visible light to prevent resin polymerization and gelation.
Safety
Eyes: Flush with clean water for at least 20 minutes and seek medical attention immediately. Skin: Remove contaminated clothing and wash thoroughly with soap and water. Not approved for food, drink, or medical application on the human body. See MSDS for details.
Machine Compatibility
RF-ZJ-02 is processed with LCD and DLP systems. The TDS lists reference starting parameters for these representative machines; validate the settings before production.
For another LCD or DLP printer, request a starting profile and validate the complete workflow before production.
Dental Model Applications
Developed for dental models, including laboratory workflows that use heat and pressure from hot-pressing molding instruments. Validate the complete cycle before production.

- 1
What is RF-ZJ-02 used for?
It is a gray, water-washable LCD/DLP resin for printing dental models. - 2
Can printed models be cleaned with water?
Yes. Rinse the surface first, then use water or IPA in an ultrasonic cleaner. Avoid high-frequency shock or forceful scrubbing to protect details. - 3
Which printing systems are listed?
The processing methods are LCD and DLP. The TDS includes reference parameters for the five representative printers shown above. - 4
What are the main post-processing steps?
Clean with water or IPA, dry thoroughly, remove supports before post-curing, and use about 5 minutes of UV curing when added toughness is required. - 5
Is RF-ZJ-02 approved for direct use on the human body?
No. The TDS states that it is not approved for food, drink, or medical application on the human body. - QHow does RF-ZJ-02 differ from RF-ZX-03 during model production?
RF-ZJ-02 offers a water-cleaning option: its TDS permits tap-water cleaning and reports 85 Shore D hardness. RF-ZX-03 specifies IPA cleaning and reports 83 Shore D. Compare the cleaning process as well as the model properties required by your laboratory; a different washing method alone does not establish equivalent printed performance. - QHow do retail and B2B resin purchasing differ?
For retail resin purchases, open the matching store product. For bulk supply or distributor pricing, send a B2B resin inquiry. Include the resin, required quantity, printer model and target market so the order and current material documentation can be matched to your workflow.
