NOVEL DUAL CURE 3D PRINTING RESINS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240279508 titled 'NOVEL DUAL CURE 3D PRINTING RESINS
The composition described in the abstract consists of an aliphatic polyurethane and a urethane (meth)acrylate prepolymer, along with optional components like a thiol, catalyst, reactive diluent, and photoinitiator.
- The aliphatic polyurethane is a reaction product of a first aliphatic polyisocyanate, a first polyol, and a thiol.
- The urethane (meth)acrylate prepolymer is a reaction product of a second aliphatic polyisocyanate, a second polyol, and an acrylate, along with a reactive diluent comprising a (meth)acrylate monomer.
- The first aliphatic polyisocyanate and second aliphatic polyisocyanate, as well as the first polyol and second polyol, may be identical or different.
Potential Applications: - 3D printing applications - Coatings - Adhesives - Sealants
Problems Solved: - Enhanced material properties - Improved adhesion - Faster curing times
Benefits: - Increased efficiency in production processes - Versatile applications in various industries - Enhanced performance characteristics
Commercial Applications: "Aliphatic Polyurethane and Urethane (Meth)acrylate Composition for Advanced Coatings and 3D Printing"
Frequently Updated Research: - Ongoing studies on optimizing curing processes - Research on expanding the range of applications for the composition
Questions about Aliphatic Polyurethane and Urethane (Meth)acrylate Composition: 1. How does the presence of a thiol impact the properties of the aliphatic polyurethane? 2. What are the key differences between using the same polyisocyanate and polyol versus different ones in the composition?
