By product type

By application area

SS628 Silicone Structural Sealant

BAIYUN SS628 Two Parts Silicone Structural Sealant is a two-component, high strength neutral curing silicone sealant designed and tested for glazing and structurally glazing 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 without primer adhesion to many substrates ensuring a durable, flexible, watertight bond

LIMITATIONS

BAIYUN SS628 Two Parts Silicone Structural Sealant should not be applied:

ŸIn 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.

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

ŸWhen surface temperatures below 10ºC (50ºF) or exceed 40ºC (104ºF)

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

ŸIn below-grade applications

ŸFor use as an interior penetration fire stop sealing system

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

ŸTo frost-laden or damp surfaces

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

ŸFor contact with strong acids or bases

ŸTo surfaces in contact with food

ŸFor continuous immersion in water

ŸFor water immersion applications.

Do not apply acid-curing (Acetoxy) silicone sealants to this product as this may cause loss of adhesion of SS628 Two Parts Silicone Structural Sealant to glass or other substrates used in the system.

 

HANDLING AND SAFETY

PRODUCT SAFETY INFORMATION REQUIRED FOR SAFE USE IS NOT INCLUDED IN THIS DOCUMENT. BEFORE HANDLING, READ PRODUCT AND MATERIAL SAFETY DATA SHEETS AND CONTAINER LABELS FOR SAFE USE, PHYSICAL AND HEALTH HAZARD INFORMATION. THE MATERIAL SAFETY DATA SHEET IS AVAILABLE FROM BAIYUN SALES APPLICATION ENGINEER, OR DISTRIBUTOR, OR BY CALLING BAIYUN CUSTOMER SERVICE.

 

HOW TO USE

BAIYUN SS628 Two Parts Silicone Structural Sealant, when used in structural applications,  must be reviewed by BAIYUN technical service specialists.

Complete design and installation guidelines are contained in the BAIYUN Technical Manual when using this product.

 

METHOD OF APPLICATION

BAIYUN SS628 Two Parts Silicone Structural Sealant should be mixed and dispensed using two-component mixing equipment, which is available from several equipment manufacturers. These mixing pumping systems are specifically designed to meter precise proportions of A base and B catalyst, in an air-free environment, and mix and dispense material at proper pressures and volumes to insure thoroughly mixed air-free material.

BAIYUN SS628 Two Parts Silicone Structural Sealant should be mixed in a ratio from 12:1 to 14:1 base to Catalyst and Base by weight, or equivalent 9:1 to 11:1 by volume for optimal properties. At this ratio, the sealant typically exhibits a working time of 20-90 minutes.
