Product Description

BAIYUN SS628 Two Parts 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:

In structural glazing applications, unless Guangzhou Baiyun Technology 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 Technology 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 10ºC (50ºF) 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 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.

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.
