Application Profile

Sealing a grain storage bin with polyurethane foam sealant

• When storing grain, use polyurethane foam one component or polyurethane foam two component to keep the bin structure watertight.
• When drying grain, use ployurethane foam to minimize heat loss.
• Use polyurethane foam to avoid water contamination and eliminate the presence of pests and rodents.
