Structural Glazing Silicone Sealant

Structural-Glazing Silicone Sealant (SG989+)

Main purposes:

npimg5 wall npimg4
  1. icn1 Structural glazing in high risk glass curtain wall;
  2. icn1 Can joint the surface of glass and metal to form a single assembly, suitable for curtain wall of SSG system design;
  3. icn1 For the situation of high requirement to adhesive safety and other purpose;
  4. icn1 Many other purposes. ?applied to structural bonding and sealing of glass, stone (marble, granite), aluminum curtain wall, glass lighting roof and metal structure engineering, bonding and sealing of large plates of glass, secondary bonding and sealing of insulating glass.)


  1. icn1 J1 Neutral Structural Silicone Sealant is RTV-1, neutral curing at room temperature, high modulus and high intensity silicone structural sealant;
  2. icn1 Excellent resistance to weather, and the service life is over 20 years in the condition of general weather;
  3. icn1 Excellent adhesion to most common building material (not including copper)without priming in general condition;
  4. icn1 Good compatibility with other neutral silicone sealants.


  1. icn1 Please follow JGJ102-2003”Technical Code for Glass Curtain Wall Engineering” in strict;
  2. icn1 The silicone sealant will release volatile compound during curing, it may be bad to heath if you in breathe the volatile compound for a long time .So please ensure adequate ventilation at workplace or curing area;
  3. icn1 The silicone sealant will not release any harmful substance and cause any damage to human body after cured;
  4. icn1 Keep uncured silicone sealant beyond children’s reach. If getting into eyes, wash with running water for several minutes, and then consult a doctor.


  1. icn1 Unsuitable for all kinds of material that can effuse grease, plasticizer or solvent;
  2. icn1 Unsuitable for the airproof location, because it is required to absorb moisture in air to cure for the silicone sealant;
  3. icn1 Unsuitable for the frosty or moist surface;
  4. icn1 Can not be used if the temperature is below 40C or above 400C on the surface of the materials;
  5. icn1 Can not be used if the surface is unclean or unfirm;

Shelf life: 12 months if keep sealing, and stored below 270C in cool, dry place after the date of production.

J1 Neutral Structural Silicone Sealant is a one part, neutral cure, versatile, high modulus architectural grade silicone sealant that exhibits outstanding physical properties projects, general building constructions as well as structural glazing adhesives uses. It has excellent weathering resistance, durability, compatibility, tensile strength; physical, mechanical and adhesive properties. Cured sealant forms tenacious bonds to substrates, typically structural glazing elements: glasses and metals members; and gives high performances silicone rubber sealant for curtain walls, for both weatherproofing and structural applications. It has the characteristics of cold resistance, heat resistance, ozone resistance, ultraviolet resistance and non-corrosion, which can ensure the safe use of the curtain wall structure for a long time.
