MasterSeal 320 

A flexible twin pack polyurethane joint filler

Description:

A twin pack polyurethane compound designed to be used as a joint filler in floors where movement is limited and reinforcing of the edges is required. Due to its good compressive properties it helps reinforce the joint against the effect of wheeled traffic, but at the same time its poor tensile strength ensures that movement at the joint faces, particularly those caused when the joint opens, does not cause spalling of the concrete

Where is MasterSeal 320 applied:

MasterSeal 320 is suitable for use as reinforcing joint filler for joints in floors designed to handle heavy, hard wheeled traffic. Recommended for use in industrial flooring applications where “joint spacing” is typically a problem.
