Industrial Equipment Maintenance & Repair:
Used for sealing joints, seams, and gaps in industrial machinery, pumps, compressors, gearboxes, and piping systems. Provides reliable sealing against dust, moisture, oils, and mild chemicals – ideal for routine maintenance and on-site repairs where quick, durable sealing is required. Excellent adhesion to metals, plastics, and ceramics commonly found in industrial equipment.
HVAC & Refrigeration Systems:
Used for sealing duct connections, air handler joints, refrigeration lines, and equipment interfaces in heating, ventilation, air conditioning, and refrigeration systems. Ensures air-tight and moisture-resistant seals that improve system efficiency and prevent energy loss. Bonds well to galvanized steel, aluminum, copper, and plastic components.
Electrical & Electronic Equipment Sealing:
Used for sealing cable entries, junction boxes, control panels, and electrical enclosures. Provides reliable protection against dust, moisture, and contaminants in industrial environments. Neutral-cure system ensures non-corrosive performance, making it safe for use with sensitive electronic components and wiring.
