Sealant-72N is a one part, neutral-cure and non-corrosive silicone sealant.

Once cured, this sealant becomes a medium modulus and flexible silicone rubber suitable for conventional glazing and weatherseal application (non-structural glazing).

This sealant contributes to the superior design and high reliability of building.

Special features:

  • One-part and neutral-cure RTV silicone sealant
  • Superior weatherability performance when exposed to a wide range of temperatures, moisture, ozone, and ultraviolet rays
  • Excellent storage stability within a wide range of temperatures
  • Excellent unprimed adhesion to most common building materials and easy-to-use in a wide range of temperature.
  • ±50% Joint movement capability of the original joint width

Standard:
- ASTM C920 Type S, Grade NS, Class 50, Use NT, G, A, M
- KS F 4910 G-25HM
