Adhesives are among the most widely used products. According to incomplete statistics, over 6,000 types of adhesives are applied across industries such as manufacturing, construction, and national defense to address bonding needs between different materials. With the rapid modernization of urban construction in China, the consumption of adhesives in building engineering and home decoration has grown quickly. Increasing attention is being paid to the quality and environmental performance of adhesives. How to provide environmentally friendly, high-performance adhesives is a critical issue facing every manufacturer.
Starting from product application areas and intended uses, we provide comprehensive testing services covering the selection of hazardous substance content and physical property items. Through authoritative third-party testing, we enable you to deliver accurate and reliable quality assurance to your customers.
