Explore our certified commercial-grade construction sealants engineered for extreme climatic resistance and structural load-bearing performance.
Strategically located in the heart of Shandong Province, a major industrial hub in China, Shandong Jinfang Adhesive Industry Co., Ltd. stands as a leading manufacturer specializing in the research, development, and production of high-performance adhesive and sealant products. With a steadfast commitment to innovation and quality, we have built a comprehensive portfolio that includes silicone sealant, PU Foam, MS sealant, nail-free glue, tile grout, and PU sealant.
Our Liquid Nails Extreme Heavy Duty products incorporate copolymer structures that resist shear forces, extreme pressure, and dramatic environmental fluctuations, ensuring zero bond failure across long lifespans.
Utilizing high-speed planetary mixing and volumetric dispensing systems, we minimize raw material variation, ensuring every batch meets consistent viscosity and mechanical profiles.
Aligning with modern green building standards (LEED v4, REACH, and GECA), we offer low-VOC solutions that provide strong structural bonding without compromising indoor air quality.
We provide comprehensive solutions tailored to the rigorous demands of the construction and automotive sectors.
Our heavy-duty nail-free adhesives offer superior load-bearing capacity for subfloors, concrete structural joints, plasterboards, and ceramic tiling. By replacing mechanical fasteners, they eliminate squeaks, distribute load stresses evenly, and prevent water ingress in external building facades.
In vehicle manufacturing, our elastomeric sealants absorb continuous mechanical vibration, dampen structural harmonics, and resist thermal expansion differences between steel, aluminum, and advanced composite materials.
We continuous invest in green chemistry and mechanical durability to keep Jinfang adhesives at the forefront of polymer science.
We are transitioning our core heavy-duty adhesives toward silane-terminated polymers (SMP). These systems combine the elastic weathering properties of traditional silicones with the high structural bond strength of polyurethanes, while remaining completely free of harmful isocyanates.
Our R&D team is developing smart-linked polymer matrices that alter glass transition temperatures under dynamic thermal stress, retaining high tensile shear strength (>3.5 MPa) in environments ranging from -45°C up to +130°C.
To support global carbon reduction goals, Jinfang's engineering pipeline aims to introduce bio-sourced tackifiers and natural oil derivatives, replacing up to 25% of traditional petroleum-based polymers without sacrificing instant grab performance.
At our manufacturing facility in Shandong, we combine advanced raw material formulation, fully automated adhesive production, precision injection molding, and intelligent packaging to guarantee consistent quality.
Our factory utilizes centralized closed-loop feeding systems and dual-shaft planetary dispersing mixers. Automated inline controls regulate moisture levels down to ppm thresholds, ensuring stability in our moisture-curing adhesives.
Our optimized manufacturing flow and raw material supply networks keep lead times stable. We ensure an average of just 15 business days from order confirmation to port dispatch, maintaining a 98% on-time delivery rate.
We combine manufacturing experience with theoretical research to drive ongoing material innovations.
Jinfang maintains deep R&D partnerships with leading Chinese universities, including Shandong University, Xiamen University, and Linyi University. These partnerships allow us to leverage high-performance analytical equipment, such as Fourier-transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA), to inspect polymer structures down to molecular levels.
We provide flexible customization services to meet the distinct project requirements of our global clients.
If you have established product formulations, we provide automated manufacturing capacity to produce material according to your technical requirements under strict quality controls.
Our technical team can adapt formulations to modify curing speeds, mechanical properties, and viscosity ranges for specific high-performance or challenging environmental installations.
We support various packaging sizes and styles, including sausage packs, standard hard plastic or aluminum tubes, and industrial bulk pails, complete with customized screen or offset printing.
With outstanding weatherability, temperature resistance, elasticity, and adhesion adaptability, silicone sealant is a core component in modern construction, glazing, and industrial fabrication.

Liquid Nails Extreme Heavy Duty is defined by its ability to achieve high initial tack—often referred to in structural engineering as "instant grab." This property is critical in vertical installation scenarios where temporary mechanical supports are impractical. The high green strength is achieved by incorporating synthetic elastomeric polymers combined with specific tackifying resins.
When the adhesive is extruded, the evaporation of carrier agents or the rapid surface moisture reaction triggers immediate physical cross-linking. This creates a cohesive network that holds structural materials, such as gypsum boards, wood framing, or wall cladding, in place. The high shear resistance is developed as the polymer chains cross-link, transforming the wet adhesive paste into an elastic, structural bond.
Outdoor construction materials are subjected to ongoing thermal cycles, UV exposure, and moisture ingress. Conventional adhesives can degrade under these conditions, leading to bond embrittlement and failures. Jinfang's heavy-duty formulations use UV-stabilized polymer backbones that resist oxidation and solar degradation.
The cured adhesive matrix functions as a viscoelastic bridge. It absorbs shear stress from the differential thermal expansion of dissimilar materials, such as bonding aluminum sheets to concrete walls. By maintaining flexibility down to -40°C and structural strength up to +120°C, the adhesive prevents cracking at the bond line, protecting the building envelope against water and air infiltration.
A key focus of our R&D team is the development of Silane-Terminated Polyethers (MS Polymers). Traditional polyurethane adhesives contain free isocyanates, which pose health concerns during application and are prone to bubbling when curing in high-humidity environments. MS polymers resolve these issues.
Our MS sealants react with atmospheric moisture through a neutral curing process, avoiding gas release and subsequent bubble formation. The resulting bond combines the UV resistance of silicone with the high mechanical strength of polyurethanes. This makes it an ideal option for modern glazing, architectural cladding, and industrial vehicle bodywork.
Producing high-performance adhesives at scale requires careful raw material management and process control. Our facility in Shandong Province uses automated weighing and planetary dispersing mixers to ensure consistent distribution of pigments, plasticizers, and polymers.
By producing our own cartridge packaging, we protect the supply chain from component shortages and maintain control over container tolerances. Our close proximity to major domestic chemical feedstocks and international shipping ports helps us offer a dependable 15-business-day shipping window, ensuring a reliable supply of adhesives for global infrastructure projects.
