Hard Splint Resin
Key Features
RF-HS-12 Hard Splint Resin is a biocompatible material for producing bite plates, occlusal splints, and retainers. It delivers high accuracy and dimensional stability, along with high abrasion resistance, high flexural strength, and high impact strength — making printed products easy to clean and reliable in long-term clinical use.

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
Open-system compatible with all major LCD / MSLA / DLP dental 3D printers. Parameter profiles available upon request.
