5.Technical Service:

Offer the integral technical data of the products.

Adhesion Test:

The products of YuanTong silicone sealant have excellent adhesion to most common building materials, as glassanodized aluminum ceramictile  granitebrickwood steel and most plastics. But we cannot ensure our sealants are suitable to all materials, as a result of the unceasing appearance of new building materials and the application of new surface treatment technology. In some cases, it is required to have the adhesion test on the substrates. In the laboratory of our company, we can carry out the adhesion test for clients and submit the test report that includes experimental result, recommended products, cleaning methods of the material surface etc.

Compatibility Test:

If the accessory materials like baker, 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 materials to us by mail (or other ways),then we will carry out the compatibility test and submit the test report.

Staining 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 staining test and submit the  test report.
