Permanent Crown Resin 55%
Key Features
The current TDS identifies RF-YG-08 55% as an A1 resin processed by LCD or DLP. It reports high strength, good hardness, high precision and high-temperature resistance, with 140 MPa tensile strength, 140–150 MPa flexural strength and Shore D 94. Its application field states “Dental model,” while the safety section says the resin is not approved for medical application on the human body.
Use-status notice
Before any clinical or patient-contact use, confirm the current intended use, regulatory status and applicability with RayForm and the responsible local professional.

Post-Processing & Storage
-
1
Wash – Clean the model with isopropyl alcohol using an ultrasonic cleaner. Avoid high-frequency or forceful brushing as it may damage the surface details of the model.
-
2
Dry – Thoroughly blow the model dry with a hair dryer or similar tool.
-
3
Remove Supports – Remove supports before post-curing. Removing supports after post-cure may damage the contact surface at support points.
-
4
Optional Post-Cure – For occasions where certain toughness is required, UV cure for 5 minutes. Store printed parts in a cool, dry place.
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-YG-08 55% is processed by LCD and DLP. The current TDS provides reference parameters for these representative printers.
Use the TDS values as starting points and validate them for your equipment and workflow.
TDS-Described Dental Workflow
The product name and TDS narrative describe permanent-crown and restorative workflows, but the same document lists the application as “Dental model” and states that the resin is not approved for medical application on the human body. Confirm current intended use and applicable documentation before patient contact.
Frequently Asked Questions
Planning a material trial? Read our temporary vs permanent crown resin selection guide for the dental lab qualification checklist and documentation checks.
- QWhat are the core TDS values for RF-YG-08 55%?
Density 1.60–1.70 g/cm³, viscosity 4500 mPa·s, Shore D 94, tensile strength 140 MPa, elongation 5%, flexural strength 140–150 MPa and flexural modulus 2500 MPa. - QWhich printing technologies and machines are listed?
The TDS specifies LCD/DLP and provides starting parameters for Phrozen Sonic Mini 8K S, Creality Halot-MAGE Pro, Elegoo Saturn 4 Ultra and Saturn 3 Ultra, Anycubic Mono 4 Ultra and M7 Pro. - QHow should parts be post-processed?
Clean with IPA in an ultrasonic cleaner without high-frequency shock or forceful brushing, dry fully, remove supports before post-curing, and use 5 minutes of UV curing when toughness is required. - QDoes this page establish clinical approval?
No. The current TDS lists “Dental model” as the application and states that the resin is not approved for medical application on the human body. Confirm current product and market documentation before patient contact. - QWhat should a lab compare before choosing 55% rather than 25% crown resin?
The 55% TDS lists A1 shade, 140 MPa tensile strength and 5% elongation at break; the 25% TDS lists A2, 120 MPa and 6%. Both list a 2500 MPa flexural modulus but different starting exposures. Compare the two TDS documents and validate each process; percentage alone does not establish suitability or safety. - 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.
