About the Manufacturer

SAINT-GOBAIN JOINLEADER (HANGZHOU) NEW MATERIALS CO., LTD. is the legal name shown on the manufacturer's website. The company's own website states that in November 2018, the Saint-Gobain group set up a joint venture with Join Leader, and this site therefore describes the company only as operating within the Saint-Gobain Joinleader joint venture system. It does not describe Saint-Gobain as the company's own brand, and it does not describe the company as directly operated by the group.

The company's own website states that Join Leader provides products and solutions of adhesives, sealants and waterproofing, that it has a nationally certified CNAS laboratory of 3,000 square metres and three factories with 45,000 square metres of workshop area, that it has more than 2,000 kinds of products, and that its products are located in more than 120 countries and regions. All of those figures are the company's own statements; no third-party verification is claimed on this site. The company's website also carries superlative slogans about being the largest exporter and having the biggest laboratory in China; those slogans are not repeated as facts on this site because no third-party evidence is published for them.

The published brands on the manufacturer's website are Join Leader and Tekbond, presented here as brand names within the joint venture system. The product range on this site covers fourteen families, from silicone sealants to tapes, spray paints and accessories. Contact is by email only on this site: [email protected].
