There are several types of bonding agents that can be used in mortar to enhance adhesion between the mortar and the substrate. Here are some examples of bonding agents commonly used in mortar:
1. Latex Bonding Agents: Latex bonding agents are based on latex polymers, such as acrylic or styrene-butadiene rubber. These agents improve the bond strength and flexibility of the mortar. Latex bonding agents are often used for bonding new mortar to existing concrete, masonry, or other surfaces.
2. Epoxy Bonding Agents: Epoxy bonding agents are two-component systems that consist of epoxy resin and a hardener. They provide excellent adhesion and high bond strength. Epoxy bonding agents are commonly used for bonding new concrete or mortar to existing concrete or for repairing concrete surfaces.
3. Polyvinyl Acetate (PVA) Bonding Agents: PVA bonding agents are based on polyvinyl acetate polymers. They improve the bond strength and workability of the mortar. PVA bonding agents are typically used for bonding new mortar to existing masonry or concrete surfaces.
4. Silane/Siloxane Bonding Agents: Silane or siloxane-based bonding agents are used to enhance the bond between mortar and masonry surfaces. They penetrate into the substrate and create a chemical bond, improving adhesion and water resistance.
5. Acrylic Bonding Agents: Acrylic bonding agents are based on acrylic polymers. They improve the bond strength and durability of the mortar. Acrylic bonding agents are often used for bonding new mortar to existing concrete or masonry surfaces.
It’s important to select the appropriate bonding agent based on the specific application, compatibility with the substrate, and manufacturer’s recommendations. Always refer to the manufacturer’s instructions and guidelines for the proper application and usage of bonding agents in mortar by foam coating machine.
