Ø        DESCRIPTION

FF9228 Silicone Structural Sealant is a two-component, neutral curing silicone sealant, specially designed for building Structural curtain wall applications with excellent weather ability and adhesion. 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 primer less adhesion to many substrates ensuring a durable, flexible, watertight bond.

Ø        CHARACTERISTICS

1  Two-part, Curing speed adjustable, Depth of fast-curing ,Suitable for construction of factory

2  Neutral curing, applied to most construction materials and will not cause adverse reactions or corrosion

3  Excellent resistance to weather, over 30 years duration under normal climatic conditions

4  Excellent resistance to low and high temperature, performance changes little between -40℃ and 150℃

5  Excellent adhesion to most common building material without using bottom coating after cured

6  Good compatibility with other neutral silicone sealants of our company.

Ø        APPLICATIONS

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

2          As a secondary edge adhesive sealant in insulating glass units.

3          Structural attachment of many panel systems. Many other uses.

Ø        TECHNICAL SPECIFICATION

Ø        APPLICABLE STANDARDS

1  China standard: GB 16776－2005

2  ASTM Specifications: ASTM C 1184－2005

RESTRICTIONS ON USE

FF9228 Silicone Structural Sealant should not be used

1  To building materials that substrates oozing grease, plasticizers or solvents– materials, such as impregnated wood, oil-based caulks, green or partially vulcanized rubber gaskets or tapes, In totally confined spaces without ventilation because sealants need absorb moisture form the air for curing.

2  The surfaces being frosted or wet, the places constantly water or wet throughout the year

3  Paint surface, paint may be peeling or cracking lead to the failure of sealing adhesive

4  the surface temperature of the materials is below 4℃ or higher than 40℃

Ø        TECHNICAL SERVICE

Adhesion Test

The laboratory of our factory can carry out the adhesion test for clients and give the test report that includes experimental result, recommended products, cleaning methods of the material surface and whether or not to use bottom coating of the material surface etc.

Compatibility Test:

If the accessory like foam strips, double-sided glue strip can not be compatible with silicone rubber, it may cause silicone rubber to turn colors, even lose adhesion. To avoid these problems, we provide services of compatibility test for clients. Clients can send the accessory to us by mail (or other ways), then we will carry out the compatibility test and give the test report.

Pollution Test:

We provide services of pollution test for clients. Clients can send the substrates to us by mail (or other ways), then we will carry out the pollution test and give the test report.

Ø        INTERFACE DESIGN

1  The interface design of the silicone structural sealant must be designed by professionals and based on JGJ102 "glass curtain wall engineering and technical norms"

2  The width and thickness of the silicone structural sealant can not be less than 6mm

3  The width of the silicone structural sealant must be greater than or equal to its depth

4  The interface of the silicone structural sealant must be able to filled up by standard constructing method

5  The interface of the silicone structural sealant must be allowed the silicone rubber in contact with air and can’t move in curing period

6  Structural silicone sealant used to support permanent load, the intension of permanent load design is 6.9Kpa

Ø        APPLICATION METHODS

Please refer to Fenfa Silicone Structural Sealants use guide

Ø        CURING TIME

1  The mixed ratio of FF9228 is A: B = 9 ~ 11:1 (volume) or 12 ~ 15:1 (weight), the recommended mixing ratio of A: B = 10:1 (volume) or 13.5:1 (weight) Increase the proportion of FF9229B can improve the curing speed, but the ratio should not exceed the scope of the above.

2  FF9228 begin to have a cross-linking reaction after the two components mixed, Tack-free time is related to the mixing ratio of the components A and B.

Ø        SAFETY TIPS

The products have no toxicity after fully cured, but before curing they should be avoided contacting with eyes. If contacted with eyes, please rinse with plenty of water and see the doctor. Ensure that it is beyond the reach of children before curing. The products in the curing process will produce Methanol, so attention should be paid to ventilation in the construction and curing area, in case of too a negative impact on human beings from Methanol.

Ø        ASSURANCE

Our factory will issue product warranty after purchase and determination of the construction units and projects.

Ø        MAINTENANCE

Not required to maintain normally. If the seam of sealant container is damaged, seal the damaged part with sealant after removing the accumulated dirt with solvent.
