Furan is a type of mortar bond coat that utilizes what?

Furan as a type of mortar bond coat utilizes catalysts to initiate and accelerate the curing process. These catalysts are essential because they facilitate the polymerization of the furan resin, resulting in a fast-setting and durable bond. This is especially important in environments that require resistance to chemicals, heat, and moisture, making furan a preferred choice in industrial applications.

While other options like water, heat, or additional cement are relevant in various bonding processes, they do not align specifically with the nature and functionality of furan bond coats. The use of catalysts is what distinguishes furan from traditional mortar bond coats, enabling it to serve its unique purpose effectively.
