DESCRIPTION

SS622 Silicone Structural Glazing Sealant is a two-component, high strength neutral curing silicone sealant designed and tested for structurally glazed curtain wall applications. Uncured, both the A and B components are thixotropic pastes and, when mixed, cure quickly to an extremely tough elastomeric silicone rubber and sealant at room temperature with primerless adhesion to many substrates ensuring a durable, flexible, watertight bond.

.

CHARACTERISTICS

   High strength and high elongation

   Odorless, non-corrosive cure system

   Excellent weatherability and high resistance to ultraviolet radiation, heat and humidity, ozone and temperature extremes

   Remains flexible over a temperature range of -55°F (-48°C) to 250°F (121°C)

   Successfully tested for use in protective glazing applications

  Excellent unprimed adhesion to wide range of substrates including coated, enameled and reflective glasses, anodized and polyester coated or painted aluminum profiles including most fluoropolymerbased paints

   Good compatibility with other neutral silicone sealants

   Meets global standards for structural glazing (American, China, Europe)

   Lot matching of base and curing agent not necessary

APPLICATIONS

   Silicone structural glazing in curtain wall; such as factory glazing of unitized curtain wall systems or in field constructed stick curtain wall systems.

   Structural attachment of many panel systems.

   Protective glazing applications.

   Panel stiffener applications.

Base: BAIYUN SS622 Base is available in 41.6 gallon drum (containing ~50 US gallons (189 L)) with a polyethylene bag liner.

Catalyst: BAIYUN SS622 Curing Agent is available in a 4.18-gallon pail (containing ~5.02 US gallons (19 L)).

LIMITATIONS

SS622 Silicone Structural Glazing Sealant should not be used, applied or is not recommended:

   In structural glazing applications unless Guangzhou Baiyun Chemical Industry CO., LTD. has reviewed shop drawings for applicability and has performed adhesion and compatibility tests on project substrates, spacer materials and all accompanying accessories. Review and testing is done on a project-by-project basis. No blanket approval is given by Guangzhou Baiyun Chemical Industry CO., LTD. for structural glazing applications. Structural glazing industry guidelines (ASTM C1401) suggest that drawings and details are to be reviewed by all parties involved in the manufacture of an SSG system and for each building project.

  To building materials that bleed oils, plasticizers or solvents – materials such as impregnated wood, oil-based caulks, green or partially vulcanized rubber gaskets or tapes

   When surface temperatures below 4ºC (39.2ºF) or exceed 40ºC (104ºF)

   Where painting of the sealant is required, as the paint film may crack and peel

   In below-grade applications

   For use as an interior penetration fire stop sealing system

   In horizontal floor joints where abrasion and physical abuse are likely to be encountered

   To frost-laden or damp surfaces

   For structural adhesion on bare metals or surfaces subject to corrosion (i.e., mill aluminum, bare steel, etc.)

   For contact with strong acids or bases

   To surfaces in contact with food

   For continuous immersion in water

   For water immersion applications.

Do not apply acid-curing (Acetoxy) silicone sealants to this product as this may cause loss of adhesion of SS622 Silicone Structural Glazing Sealant to glass, and/or other substrates used in the system.

TECHNICAL SERVICES

Complete technical information and literature are available from Guangzhou Baiyun Chemical Industry CO., LTD.

The following materials are required to be submitted to Guangzhou Baiyun Chemical Industry CO., LTD. to receive suggestions for the use of SS622 Silicone Structural Glazing Sealant.

   Architectural and shop drawings for review and comment.

   Design wind load requirement(s) for project.

   Glass or panel sizes.

   Production samples of metal, glass, gaskets, spacers and setting blocks with type and manufacturer identified.

   Specification and/or identification of paint or finish to which SS622 Silicone Structural Glazing Sealant is intended to adhere (i.e., 215-R1 anodized or if paint; manufacturer, finish system and ID#).

Guangzhou Baiyun Chemical Industry CO., LTD. will provide the following, after reviewing the materials above:

   Determination as to whether the submitted joint dimensions meet the minimum design criteria necessary for the use of SS622 Silicone Structural Glazing Sealant.

   Short-term adhesion data using (typically) the ASTM C794 and/or ASTM C1135 test method. Other test methods may be employed.

  Short-term compatibility test results on gaskets, spacers and setting blocks and other accessories per ASTM C1087 or Guangzhou Baiyun Chemical Industry CO., LTD. test method for compatibility.

   Information regarding suggested primers, when required.

Guangzhou Baiyun Chemical Industry CO., LTD. will not:

   Design sealant joints.

   Provide comments on the structural integrity of overall framing system(s).
