Engineered to meet the rigorous demands of construction and industrial assembly lines globally.
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.
Through relentless iteration of formulation chemistry and state-of-the-art automated production lines, Jinfang has solved critical challenges in adhesive science, specifically optimizing clear construction adhesives for non-yellowing, elastic recovery, and instant tack under varying climate zones.
How structural advancements in Hybrid MS Polymers and Polyurethanes are replacing physical fasteners.
The transition from traditional solvent-based neoprene formulas to Silane Modified Polymers (MS Polymers) represents the biggest shift in construction adhesives. The market increasingly demands 100% solids, zero-solvent formulations that offer optical clarity, minimal shrinkage, and no volumetric collapse during the cure profile. Jinfang's MS Crystal Clear technology addresses this by using custom catalyst matrices to ensure fast cross-linking without bubbles.
Architectural glazing, interior glass mosaic tiling, and modern frameless construction designs necessitate completely clear joints. Traditional "nail-free" glues leave visible, unsightly margins. The newest clear liquid nail iterations match the refractive index of commercial glass, creating an invisible bond line that remains stable even when subjected to intense, concentrated UV radiation.
Contractors globally cannot afford failure points in structural adhesive joints. Jinfang's integration of precise raw material formulation, fully automated adhesive production, and intelligent packaging ensures that physical performance parameters, such as shear strength and aging coefficients, remain consistent from batch to batch.
Understanding what structural engineers, product managers, and procurement leads require.
In B2B sourcing, selecting the right clear liquid nail manufacturer is not just about price. Buyers look at high-precision performance factors that dictate safety, longevity, and regulatory compliance.
Adhesives exposed to sunlight can degrade and turn amber. Our formulations use hindered amine light stabilizers (HALS) and UV absorbers to keep bonds transparent long-term.
Determining the tensile shear capacity (measured in MPa) is critical to ensure the adhesive handles joint movements and structural loads without cohesive failure.
Global import requires compliance with regional environmental rules, including ISO 9001/14001, European IROS, and CE standards.

Durable protection for structural joints, weatherproofing, and glass bonding.
With outstanding weatherability, temperature resistance, elasticity, and adhesion adaptability, silicone sealant is an essential material in modern construction and home improvement.
It remains stable under extreme conditions, providing weatherproofing and seal stability for structural curtain walls, perimeter joints, and interior wet areas.
Answers to common technical, shipping, and chemical engineering questions.
Yellowing in clear adhesives is typically caused by UV-induced breakdown of the polymer backbone, often accelerated by certain catalysts and plasticizers. Our formulations use aliphatic polymer backbones combined with Hindered Amine Light Stabilizers (HALS) and UV absorbers. This prevents yellowing even under exposure to sunlight, passing xenon arc tests without significant color change.
While screws and nails provide localized mechanical points, clear liquid nails distribute stress evenly across the entire surface. This prevents concentration points, dampens vibrations, and seals joints from air and moisture. However, for structural, load-bearing applications, they are often paired with mechanical fasteners to handle permanent static loads.
When stored in their original unopened packaging in dry, cool conditions (between +5°C and +25°C), our MS and PU sealants have a shelf life of 9 to 12 months. Since moisture triggers the curing process, protecting the cartridges from humidity during storage is essential to prevent premature curing inside the nozzle.
For standard formulas with private label packaging, our average production lead time is 15 business days after design approval. The Minimum Order Quantity (MOQ) depends on the packaging configuration—usually starting at 10,000 units for custom printed 300ml cartridges, and lower volumes for larger industrial packaging like sausages or drums.
Our MS Polymer adhesives are paintable once fully cured. They can be coated with most water-based and industrial paints. However, we recommend testing compatibility with specific paints before full application, as some high-solvent coatings can affect cure rate and elasticity.
We maintain consistent quality through fully automated compounding systems that control temperature, mixing speed, and pressure. Every batch is tested in our lab for key metrics, including viscosity, skin time, cure rate, and tensile strength, before packaging.
We prioritize low emissions. Our main water-based acrylics and MS polymer sealants meet ISO 14001 guidelines and comply with international VOC limits. This supports LEED v4 and BREEAM certifications for green building projects.
