Sealing and Adhesive Material Testing

China’s sealant and adhesive material industry started at the end of the last century. With the rapid development of construction, automotive, new energy and other fields, the increasing requirements for material sealing performance, durability and environmental friendliness have driven industrial technological upgrades and product iteration. Especially since the beginning of this century, guided by national energy-saving and environmental policies, the demand for high-performance sealants and green adhesives has grown significantly, becoming a key driver of industry development. In recent years, with the expansion of emerging applications such as prefabricated construction, electronic packaging and photovoltaic modules, sealant and adhesive materials have entered a new phase of rapid growth. Since 2014, the average annual growth rate has continuously exceeded 30%, making China the world’s largest producer and consumer market for sealant and adhesive materials.

We have a professional testing team and advanced laboratory equipment. We can provide you with differentiated testing services for sealant and adhesive materials, covering key items such as bond strength, durability and environmental indicators. Our services help your products highlight performance advantages under standard requirements and enhance market competitiveness.
