Direct from Shandong Jinfang's production hub: high-spec building envelope formulations designed for global distribution pipelines.
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.
Supported by a robust R&D infrastructure and a dedicated technical team, we maintain deep R&D partnerships with leading Chinese universities, including Shandong University, Xiamen University, and Linyi University, leveraging these collaborations to recruit top-tier research talent.
We have built an integrated manufacturing system that encompasses precise raw material formulation, fully automated adhesive production, precision injection molding, and intelligent packaging. Supported by advanced equipment and intelligent process control, this system ensures consistent product quality. The company has obtained a series of enterprise and product certifications, including ISO 9001, ISO 14001, and the EU IROS. We are committed to achieving green and sustainable high-quality development.
From Glossy Reflection to Matte Realism: Understanding the Architectural Shift in Modern Building Envelopes.
Traditional silicone sealants feature high surface specular glossiness (often exceeding 80 units), causing distracting reflections and highlights on joints. Our advanced Matt Silicone Sealants are engineered with synthetic fumed silica and precise matting agents that create sub-micron surface micro-roughness. This micro-texture scatters incident light, lowering gloss levels to under 10 units for a completely flat finish.
By blending structural integrity with aesthetic neutrality, our matte formulations eliminate the "wet-look" greasy appearance common in exterior sealants. This design matches non-reflective structural claddings, including anodized aluminum plates, natural sandstone, limestone, matte terracotta panels, and contemporary fiber-cement rainscreen systems.
Our formulation controls plasticizer migration, ensuring zero oily exudates bleed into adjacent porous natural stone. This prevents chemical staining (dark halos around joint edges) and minimizes airborne dirt pick-up, maintaining pristine, clean facades over decades.
Ensuring reliability in multinational supply chains, commercial development projects, and industrial manufacturing plants.
Global architectural bids require compliance with strict environmental standards. Our neutral cure formulations are designed to meet international VOC limits, obtaining certifications such as LEED v4.1, BREEAM, EMICODE EC1 Plus, and French VOC Regulation Class A+. Eliminating harmful solvents and MEKO (Methyl Ethyl Ketoxime) emissions ensures safety for indoor cleanrooms and public environments.
Commercial building envelopes face thermal expansion and contraction cycles. Our structural and weatherproof matte sealants conform to ASTM C920 Class 50 and ISO 11600 25LM specifications. They deliver ±50% movement capacity, high elastic recovery, and resist weathering, UV radiation, ozone, and extreme temperatures (-50°C to +150°C) without cracking or peeling.
How Jinfang implements smart manufacturing to reduce costs, optimize turnaround times, and guarantee high product quality.
Our production utilizes fully enclosed planetary mixers and dynamic loss-in-weight feeders. Raw base polymers, cross-linkers, catalysts, and matting silica agents are dosed continuously to prevent humidity introduction, ensuring high batch consistency and long-term shelf-life stability.
By integrating cartridge manufacturing, offset printing, and high-speed filling on a single shop floor, we minimize intermediate material transport damage. This automated line guarantees precise filling quantities and air-free packaging, eliminating application failures on-site.
Located in Shandong Province—the center of China's silicone chemical industry—we maintain direct supply links with premium organosilicon suppliers. This ensures stable raw material supply, offering protection against global price fluctuations and supply disruptions.
Understanding the unique needs of our global clients, we offer flexible OEM and customization services. Our expert technical team works closely with customers to tailor product specifications, packaging, and formulations to their exact project requirements. This client-centric approach, backed by stringent quality control from raw material sourcing to finished product, has been instrumental in our successful international expansion.
Tailoring viscosity, curing speed, gloss levels, and mechanical modulus to meet specific environmental needs.
Flexible choices from 300ml rigid cartridges, 590ml foil sausages, to bulk drums, with tailored brand labeling.
Ensuring reliable weatherproofing and durable bonding under demanding environmental conditions.
Ideal for commercial high-rise buildings where a non-glossy, matte finish is required to prevent visual disruption. Excellent UV resistance protects joints against degradation under intense solar radiation.
Used in high-traffic commercial building floors, plazas, and facades. Polyurethane and silicone hybrids with high-movement elasticity accommodate concrete slab shifting and temperature fluctuations.
Formulated with anti-microbial additives for kitchens, bathrooms, laboratories, and pharmaceutical cleanrooms, resisting mold, mildew growth, and exposure to cleaning chemicals.
Expert insights from our chemical R&D department to help you optimize installation and selection processes.
The difference lies in surface light-diffusion chemistry. Glossy silicone sealants cure with a smooth, reflective polymeric surface. Our matte silicone sealants contain specialized synthetic micro-silica particles that disperse during curing. This forms a micro-structured surface that diffuses light, reducing visible gloss to under 10% (matte) without compromising raw mechanical strength, tear-resistance, or adhesive elasticity.
No. The matting agent is physically integrated into the silicone polymer matrix. Under accelerated aging tests (including UV irradiation, moisture condensation, and ozone chambers), our matte silicone sealant retains its elastomeric properties, adhesive strength, and color stability comparable to high-gloss architectural-grade sealants.
Neutral Alkoxy curing release non-corrosive alcohols instead of acetic acid (acetoxy cure) or MEKO (oxime cure). Alkoxy is highly recommended for sensitive substrates like natural limestone, marble, copper, steel, and coated insulating glass. It protects mirror backing and laminated glass interlayers from chemical degradation and corrosion.
Our sealant offers excellent primerless adhesion to glass, anodized aluminum, PVDF-coated steel, clean concrete, masonry, glazed ceramics, and most plastics. For extremely porous natural stones, fiber cement, or low-energy plastics (PP, PE, PTFE), we recommend applying a dedicated surface primer to maximize mechanical bonding.
We operate under a strict ISO 9001 and ISO 14001 Quality Management System. Each production batch undergoes online viscometry, extrusion rate monitoring, and lab testing for skin-over time, tack-free time, durometer hardness (Shore A), and tensile adhesion. Retained samples are kept for 24 months to ensure full quality traceability.
Full portfolio solutions for commercial structural glazing, tile grouting, and interior air-barrier installations.
