LIGBOND: Sustainable Drop-In Binder for Carbon-Containing Refractories
LIGBOND is a phenol-formaldehyde-free binder developed as a drop-in alternative to conventional phenolic resin for carbon-containing refractories.
It is designed for use in MgO-C and other carbon-containing refractory products without fundamental changes to existing raw materials, mixing procedures, pressing conditions, curing systems, or production equipment.
LIGBOND combines excellent graphite wetting, stable processing behavior, high carbon yield, and the formation of a dense carbon-bond structure after carbonization.
Its objective is simple to provide the processing reliability and refractory performance expected from conventional phenolic resin while reducing dependence on phenol-formaldehyde-based binder systems.
Why LIGBOND
A Practical Alternative to Phenolic Resin.
The challenge in replacing phenolic resin is not simply to develop a bio-based or environmentally preferable binder.
A practical refractory binder must satisfy the complete manufacturing and performance requirements of carbon-containing refractories.
LIGBOND has been developed specifically for this purpose
Characteristics of LIGBOND
Phenol-formaldehyde-free: Contains no Phenol, Cresol, Xylenol, Toluene, Benzene, Benz(a)pyrene, etc.
Guarantees Excellent Workability: It has good wettability for graphite, so mixing is excellent.
100% Compatible with Existing Production Processes: It can be used perfectly identical to the mixing, molding, and curing processes of existing phenolic resins (Curing Temperature: 200~220℃).
Maintains Excellent Physical Properties: It has secured physical properties at a level similar to products using phenolic resin, and specifically, its HMOR is good.
Heat Treatment Stability: Excessive expansion or contraction does not occur during the heat treatment process.
Efficient Carbonization: Lignin carbonizes stably after reduction firing.
Minimizes Burden of Waste Recycling: Since there is no phenol-formaldehyde component, it drastically reduces the environmental burden that occurs when recycling waste bricks later.
Excellent Long-term Storage: It can be stably stored for 6 months in a sealed state.
