Pre-sales-1. Product recommendation
According to the construction type, design requirements and curtain wall materials, we recommend the most suitable sealant.

Pre-sales-2. Details confirmation
Our engineers confirm with the client regarding sealant size, material type and joint design, and offer a report.

Pre-sales-3. Sample testing
We perform the adhesion test, compatibility test, staining test and other tests to provide the correct construction instructions.
The adhesion test is conducted to determine the proper cleaning solvent and decide whether it’s necessary to cover a base coat.

Adhesion test (GB 16776-2005 construction silicone sealant)
The test materials and sealants are of excellent adhesion.

Compatibility test (GB 16776-2005 construction silicone sealant)
The compatibility test is to make sure that the substrate will not discolor and affect the bonding effect.

Test specimens of compatibility test
During the compatibility test, if the specimen discolors, the sealant will not be used.

Staining test (GB/T 23261-2009 stone silicone sealant)
According to the result of the staining test, we choose the sealant product that will most effectively seal the stone or similarly porous materials, ensuring the sealant is suitable for the stone curtain wall and avoids stains.

Staining test oven
The specimen is compressed to 50% and tested in the oven at 70 degrees.

Pre-sales-4. Amount estimation
We estimate the total sealant consumption depending on the curtain wall design information supplied by client.

During sales-1. Technical communication
Our employees visit the client’s construction site and discuss the sealing requirements with the client.
