Description

SEALANT-72N is a one-part, neutral-cure, odorless and non-corrosive silicone sealant.  Once cured, this sealant becomes a medium modulus and flexible silicone rubber suitable for conventional glazing and weatherseal applications (non-structural glazing).  This sealant contributes to the superior design and high reliability of buildings.

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 temperatures
  • +50% Joint Movement Capability of the original joint width

*RTV stands for ‘room temperature vulcanizing’ which means that this material can be cured at room temperature

Applications

  • Conventional glazing and weatherseal applications
  • Polycarbonate and other plastic joint

SURFACE PREPARATION

All surfaces must be clean, dry, sound, and free from dust, oil, rust, or any other contamination.

Metals should be cleaned with a non-oily solvent soaked clean cloth, such as PROSIL CLEANER 1. Excess solvent should be wiped from the surface with a clean dry cloth. When used on remedial work all existing sealant must be removed. In some instances further cleaning or etching maybe required.
