Silicone and Polyurethane Sealants

PTFE Bushings

WEICON's silicone and polyurethane sealants are durable, paintable, and resistant to weather, aging, fresh and salt water. 

These flexible adhesives and sealants are often based on polyurethane (PUR) or silicone and may be used to bond and seal a wide range of materials, including metals, plastics, ceramics, wood, glass, and stone.

WEICON Silicone and Polyurethane Sealants can be utilized in tank and apparatus engineering, carriage, container and vehicle building, ventilation and air conditioning systems, and the energy and electrical industries.

Key Features:

  • Durability: WEICON's silicone and polyurethane sealants remain effective over time, especially under tough circumstances.
  • Paintability: Many formulations may be painted over, providing for seamless incorporation with existing surfaces.
  • Weather resistance: WEICON's silicone and polyurethane sealants can survive UV radiation, rain, and temperature variations.
  • Aging resistance: The sealants maintain their characteristics for long periods of time without considerable breakdown.
  • Water resistance: They efficiently protect against both fresh and saltwater incursion.

Applications:

  • Automotive: Sealing joints, gaps, and seams in car bodywork and components.
  • Construction involves weatherproofing windows, doors, and expansion joints.
  • Marine: Bonding and sealing in boat construction and repair.
  • Industrial: Putting together equipment and mechanical components.
  • Plumbing involves sealing pipes, fittings, and connections.
