Approved by the China National Accreditation Service for Conformity Assessment (CNAS), our R&D center is equipped with a comprehensive range of more than 60 sets of national-level and international-level testing instruments and devices, enabling us to perform several levels of product testing programs. In mechanics lab, test items include tensile strength, bonding strength, displacement capacity, elongation and other physical properties.

According to the construction type, design requirement and curtain wall materials, we recommend the most suitable sealant. Our engineers confirm with the client regarding sealant size, material type and joint design. Next we perform an adhesion test to determine the proper cleaning solvent and decide whether it’s necessary to cover a base coat.
