Shanghai Junbond Building Material CO.LTD

Silicon sealants are widely used in construction for waterproofing and bonding, especially in high-humidity environments like bathrooms and balconies. Shanghai Junbond Building Material CO.LTD has been in business since 2016, which shows they have experience in a competitive market and can offer reliable product performance. The lack of verified phone, work email, and business documents raises concerns about their legitimacy and responsiveness — buyers should request additional proof before placing large orders. While the company is based in China, a major manufacturing hub for building materials, the absence of verification makes it harder to trust their ability to meet specific technical or delivery requirements. Having a verified account email is a basic step for credibility, and its absence adds to the risk. Buyers should confirm contact details and business documents directly before initiating any trade discussions.
