Gamma-hydroxy carbonates as biodegradable and reversible crosslinkers
Innovative gamma-hydroxy carbonates offer a biodegradable and reversible crosslinking solution for thermoplastic resins, applicable in hot melt adhesives, powder coatings, and as asphalt replacements. This technology enhances adhesion and sustainability in various industrial applications.
Overview
Gamma-hydroxy carbonates are revolutionizing the field of thermoplastic resins with their ability to act as biodegradable and reversible crosslinkers. Developed by Instrumental Polymer Technologies, this innovative solution provides a sustainable alternative to traditional crosslinking agents. By heating above 120°C, these carbonates facilitate a reversible crosslinking process that can be utilized in hot melt adhesives, low bake powder coatings, and even as an asphalt replacement. The technology not only promises enhanced performance but also aligns with environmental sustainability goals.
Technical specifications
Key features include:
- Reversible crosslinking: Achieved by heating above 120°C, enabling a transition from a solid state to a low viscosity liquid and back.
- Biodegradable: Utilizes sustainable raw materials, making the resulting systems environmentally friendly.
- Versatile applications: Applicable in coil coatings, hot melt adhesives, and powder coatings, offering improved adhesion to metals and glass.
- Snap-set cure: A unique feature that leverages the kinetic reactivity of hydroxyls with carbonates, forming a highly strained six-membered ring.
Technology readiness level
