Engineered for structural durability, thermal performance, and environmental compliance.
Where industry-leading academic research meets high-capacity automated production lines.
Shandong Jinfang Adhesive Industry Co., Ltd.
Strategically located in the heart of Shandong Province, a major industrial hub in China, we stand 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.
We maintain deep R&D partnerships with leading Chinese academic institutions, including Shandong University, Xiamen University, and Linyi University. This dynamic collaborative network enables us to recruit top-tier research talent, translate advanced polymer science into commercial formulas, and maintain our edge at the forefront of global adhesive technology. Our integrated manufacturing system encompasses precise raw material formulation, fully automated adhesive production, precision injection molding, and intelligent packaging under ISO 9001, ISO 14001, and EU IROS standards.
Technological transformations shaping the next generation of architectural adhesives.
Strict global regulations (e.g., EU REACH, EMICODE EC1 Plus, and US SCAQMD Rule 1168) are pushing the industry from traditional solvent-based formulations toward bio-derived water-based acrylics and hybrid MS polymers, ensuring indoor air quality safety.
MS polymers represent the fastest-growing sector for interior joints. By combining the UV resistance of silicones with the paintability and strength of polyurethanes, they prevent plasticizer migration and minimize staining on substrates.
Modern off-site construction demands sealants with high elastic recovery and rapid curing profiles to withstand transport stresses and structural shifts in modular building envelopes.
A technical guide to selecting the appropriate chemical composition based on performance requirements.
| Performance Characteristic | MS Polymer (Modified Silane) | Neutral/Acetic Silicone | Polyurethane (PU) | Water-Based Acrylic |
|---|---|---|---|---|
| Movement Capability | High (±25% to ±50%) | Very High (±50%) | High (±25%) | Low-Medium (±12.5%) |
| Paintability | Excellent (Water-based coatings) | Non-Paintable | Excellent (Requires primer) | Excellent (Direct coat) |
| VOC Emissions & Odor | Extremely Low / Odorless | Low (Neutral) / Sharp (Acetic) | Moderate (Isocyanate content) | Virtually Zero / Odorless |
| Substrate Adhesion | Primeless on most (Porous/Non-porous) | Excellent on glass, ceramic, metals | Excellent on masonry, concrete | Good on drywall, wood, plaster |
| Primary Applications | Cleanrooms, perimeter joints, interior floors | Glazing, sanitary, kitchen & bath | Expansion joints, automotive body structural | Drywall joint filling, skirting boards, gap sealing |
Eliminating supply chain uncertainties through bespoke formulation and strict quality assurance.
Our dedicated laboratory adjusts shore hardness, cure speed, and viscosity profiles to perform under specific regional climate conditions, from high-humidity equatorial zones to freezing sub-arctic climates.
We pack in standard 300ml rigid plastic/aluminum cartridges, 600ml foil sausages, and bulk 200L drums, offering custom printing (offset/screen) to fit white-label and private-label branding initiatives.
From custom chemical formulation and precision tooling for plastic cartridges to robotic filling lines and automated carton packaging, we manage the entire value chain in-house to reduce lead times.
Solving engineering challenges across commercial, industrial, and transportation sectors.
Our MS crystal clear and water-based acrylic sealants are formulated with anti-microbial and anti-fungal agents to prevent mold growth inside ventilation ducts. These systems meet strict hygiene requirements for microelectronics and pharmaceutical cleanroom settings.
For modern multi-family residential and high-rise office towers, our B1 fire-retardant PU foams and specialized acrylic intumescent sealants prevent fire spread and air leakage, providing acoustic insulation to achieve high Sound Transmission Class (STC) ratings.
Our professional-grade polyurethane and MS polymer formulations supply automakers and repair facilities with high-elongation adhesive bounds that reduce vibration, dampen noise (NVH control), and seal joints against environmental moisture.
Driving sustainable sealant chemistry and manufacturing innovation over the next decade.
Our research partnership with Shandong University focuses on substituting petroleum-based polyols and silicon fluid backbones with plant-derived, renewable organic acids and natural silicates to reduce product carbon footprint.
To prepare for upcoming toxicological restrictions on organotin catalysts used in silicone and MS polymer curing, we are developing alternative titanium and organic amine catalyst platforms that maintain long shelf-life and fast tack-free times.
We are piloting micro-encapsulated healing agents within polyurethanes. When micro-fractures occur due to seismic stress or building settling, the capsules rupture, releasing reactive monomers that seal the crack and restore structural integrity.
