In-Depth Review TG4G Review ·2026-06-26 · For reference only

Basic Site Overview

sealant-cn.com is the official B2B website for Longkou Tengyu Chemical, a chemical manufacturer based in Shandong, China. Founded in 2013, the company specializes in the R&D, production and export of a full range of sealing and bonding products. The website primarily serves global customers to showcase product lines, introduce application solutions, and coordinate custom development requests.

Core Services & Products

The site’s core business is split into two main categories: First, it handles sales of the company’s own full line of branded sealing products, covering acrylic sealant, silicone sealant, polyurethane sealant, MS modified silane sealant, waterproof coating, epoxy adhesive, and more than 50 other products. These products serve over a dozen industry scenarios including construction and renovation, automotive manufacturing, new energy vehicles, and prefabricated construction. Second, the company offers end-to-end OEM/ODM customization services: they can complete product design, sample prototyping, and mass production fully tailored to customer requirements. The customization process is clear and standardized, and private-label production is supported, with a minimum order quantity of 2400 units for private labeling.

The company operates an independent R&D center with a 30-member technical team, holds over 60 patents both in China and abroad, posts annual sales exceeding 50 million USD, exports products to more than 150 countries and regions worldwide, and has the capacity to fulfill large-volume orders.

Pros, Cons & Ideal Users

Advantages: Full product coverage, solid in-house R&D capability, mature and standardized customization process, and fast response times, that can meet the procurement needs of B2B clients of all sizes.
Disadvantages: The official website does not display public pricing, it only supports B2B wholesale and customization and does not offer retail to individual customers. In addition, there is no dedicated Chinese-language interface for domestic Chinese clients, making browsing inconvenient for local users.

This website is ideal for procurement and business matching for B2B clients including global building materials distributors, construction contractors, automotive and new energy vehicle manufacturers, and existing sealant brands. It is not suitable for individual consumers making small, personal purchases.

Accessibility for Users in China

Users based in China can access the website directly and normally, no VPN proxy is required.
