What is PU Sealant?

PU Mastik is a multi-purpose sealant widely used in both the construction and automotive industries. Available in two-component or single-component versions, it acquires a flexible, rubber-like structure after drying. This provides excellent resistance to external factors such as vibration and impact. It is frequently preferred for sealing in the automotive industry and for joint filling in construction.

PU Sealant Properties

  • Dual sector compatibility: The ideal formula for construction and automotive applications.
  • Superior flexibility: Adapts to structural movements, preventing crack formation.
  • Waterproof: Offers excellent water and moisture resistance.
  • UV resistance: Shows high resistance to sunlight.
  • Strong adhesion: Effective bonding to various surfaces such as concrete, wood, metal, and glass.
  • Easy application: Can be easily applied with a sealant gun.
  • Paint compatibility: It can be painted over after it dries.
  • Fast curing: Dries quickly depending on ambient conditions.
  • Chemical resistance: Shows resistance to certain chemicals.

PU Sealant Application Tips

  • Before starting the application, ensure the surface is dust-free, dry, and clean. A surface primer can be used if necessary.
  • Applying masking tape to the area where the sealant will be applied provides a cleaner look and prevents leakage.
  • Using the correct joint filler according to the width and depth of the joint helps to achieve a professional result.
  • After application, the sealant should be evenly squeezed into the joint using a sealant gun and smoothed with a spatula within approximately 5-10 minutes.
  • Care should be taken to prevent water contact with the surface during the curing period. Full drying time may vary depending on the product type and environmental conditions.
  • If painting is necessary, the surface can be sanded after the sealant has completely dried to achieve a smoother finish.
