changing materials and the compatibilities between surface treatment and materials. Our company gives construction
project give technical services as follows:
Adhesion Testing
Our company Silicone will evaluate tests about the adhesion of our products to job site or representative job site materials
in standard laboratory. Results of the adhesion testing, product
Recommendations and surface preparation will be forwarded in writing.
Compatibility Testing
Incompatibility of glazing materials can lead to sealant discoloration and/or loss of adhesion. To help protect against
these problems and to ensure compatibility, ZHONGTUO will also test and provide information on the compatibility
of accessory materials (gaskets, spacers, etc.) and other ZHONGTUO Silicone sealants.
Stain Testing
Because of the staining problems that may occur with porous substrates,ZHONGTUO is willing to run laboratory tests
and provide information to you on the possibility of staining occurring with the construction materials being used.
