6.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 glass,anodized aluminum, ceramictile,  granite,brick,wood ,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.

7.Warranty

As an ISO:9001 certified company, we are committed to establishand implement the ISO:9001 Quality Management System.

8 .Maintenance

Generally there needs no repairing. If impaired in sealing Joints, clean with proper solvent and repair with our products.That can adhere well.

Important

The information contained in this instruction is correct. However, by no means can it be considered an absolute guarantee, as usage and application of the product in accordance with the instruction given and their success in application is beyond our control and is dependent on a number of factors. Clients should have a good knowledge of the product and make independent  judgments of optimal usage before application.
