With outstanding weatherability, temperature resistance, elasticity, and adhesion adaptability, silicone sealant has become an indispensable high-performance material.
Modern skyscraper designs rely heavily on structural glazing to maximize glass area and aesthetic sleekness. In these systems, structural silicone sealant forms the vital structural bond. Jinfang's architectural sealants withstand significant wind-load stress, seismic shear shifts, and thermal expansions, ensuring a safe building envelope. They provide long-term weatherproofing, thermal insulation, and structural integrity.
In the automotive sector, our sealants contribute to enhanced vehicle safety, noise reduction, and comfort. They provide durable damping properties, components bonding, and air/water sealing for windshield glass installation, sheet metal joints, and electronic housing elements, keeping out environmental debris and dampness.
Our solutions have earned trust in critical regional markets including Europe, Asia, and South America. We are dedicated to fostering long-term collaborations by delivering not just products, but comprehensive, reliable, and innovative sealing solutions that build value and success for our customers everywhere.
Leading the transition toward low-VOC, carbon-neutral, and bio-based adhesive solutions for the modern green building era.
In accordance with stringent international standards such as European EMICODE EC1 Plus, French A+ Regulations, and South Coast Air Quality Management District (SCAQMD) Rule 1168, Jinfang has minimized Volatile Organic Compounds in our formulations. Our water-based acrylics and neutral-cure silicone lines feature minimal VOC content, eliminating the release of offensive odors and toxic outgassing during indoor cure cycles. This facilitates points collection under major green building certification programs like LEED v4.1 and BREEAM.
Our long-term R&D roadmap focuses on replacing fossil-fuel-derived polydimethylsiloxane (PDMS) backbones with bio-based silicones derived from sustainable agricultural waste or plant-based raw materials. By partnering with domestic academic laboratories, we aim to decrease the carbon footprint of structural silicones by up to 30% over the next decade, while maintaining structural performance and tensile limits.
The environmental impact of a building facade is evaluated over decades. By engineering structural sealants with elevated UV resistance and thermal stability, Jinfang products prevent premature joint failure. A joint that survives 30 to 40 years without remediation saves significant raw materials, energy, and labor, lowering the environmental impact of modern architecture.
In-depth technical answers addressing application limits, curing, compatibility, and compliance protocols.
A: Structural silicone sealants are specifically formulated and certified (e.g., ASTM C1184, ETAG 002) to bear continuous tensile, shear, and compressive loads. They act as the structural "glue" that attaches glass, stone, or metal cladding panels to the building structure without mechanical framing. Weatherproofing sealants, on the other hand, are engineered primarily for high movement capacity (typically ± 50% or ± 100%) and UV/moisture resistance. They fill joints to prevent environmental ingress but lack the high tensile adhesion modulus required to carry permanent dead loads or wind loads.
A: Compatibility testing (in accordance with ASTM C1087) determines if accessories like spacers, gaskets, setting blocks, backer rods, and anodized aluminum profiles release plasticizers or oils that degrade the silicone bond. If incompatible components contact the structural silicone, it can lead to cohesive failure, discoloration, or complete detachment of the glass pane. Jinfang provides professional project compatibility testing in our corporate laboratories and issues official project certifications.
A: The choice depends heavily on where the glazing is executed. One-component sealants cure via atmospheric moisture, meaning the curing speed is dependent on humidity and temperature. This is highly suitable for on-site glazing, remediation work, or small-scale fabrication. Two-component sealants cure chemically throughout the joint depth once base and catalyst are mixed. Curing is fast and independent of humidity (achieving full structural strength within 24 to 48 hours), making it optimal for factory-controlled curtain wall production lines where rapid turnover of glazed frames is necessary.
A: "Structural bite" is the width of the structural silicone sealant joint that contacts both the glass panel and the metal support frame. It is designed to transfer wind load stresses and dead load forces from the glass to the frame. The calculation follows the trapezoidal wind load distribution method or the rectilineal method based on maximum wind pressure (Pa), glass dimensions (height and width), and the design stress limit of the silicone (typically 138 kPa for dynamic loads). Our technical engineering department assists clients in calculating exact bite dimensions for safety.
A: Proper cleaning is crucial. We recommend the "two-rag cleaning method." The first lint-free white rag is saturated with an approved cleaning solvent (e.g., Isopropyl alcohol or Methyl Ethyl Ketone) to wipe the substrate clean. The second clean, dry rag immediately follows to wipe the solvent off before it evaporates and redeposits contaminants. No primer should be applied unless specific adhesion tests dictate its necessity. Silicone must be extruded immediately after cleaning to prevent dust re-accumulation.
A: Our ISO 9001 and ISO 14001 certified plant employs fully automated raw material dosing and continuous processing. Each batch undergoes rigorous quality control checks, including extrusion rate testing, non-sag testing, density checks, tack-free time measurements, and mechanical performance verification (tensile strength and elongation at break). For two-component systems, we conduct daily butterfly tests to confirm uniform mixing of base and catalyst.
A: Alkoxy curing silicones release non-corrosive, mild alcohols (methanol or ethanol) during curing, which makes them highly compatible with all coated glass surfaces, copper, brass, and plastics without causing corrosion. Oxime curing silicones release methyl ethyl ketoxime (MEKO). While they offer excellent adhesion and shelf life, they may pose environmental and health challenges (subject to strict inhalation limits in Europe) and can cause light corrosion on certain sensitive metal foils. Jinfang provides optimized alkoxy formulations to meet European environmental regulations.
A: Modified Silane (MS) polymers combine the high weather and UV resistance of silicones with the paintability and non-staining characteristics of polyurethanes. They are excellent for perimeter joints, interior visible joints, and hybrid structural bonding where paint coat compatibility is required. However, for structural glazing curtain walls with continuous exposure to heavy wind loads and direct solar UV radiation, traditional high-performance structural silicones remain the industry standard due to their higher silicone-oxygen (Si-O) bond energy.
A: For European markets, structural sealants must hold European Technical Assessments (ETA) verifying compliance with ETAG 002 guidelines, and bear CE marking. In North America, they must conform to ASTM C1184 (Standard Specification for Structural Silicone Sealants) and meet the requirements of ASTM C920 (movement class). Jinfang's architectural lines conform to these international benchmarks, ensuring compliance for global project deployment.
A: The standard shelf life of Jinfang silicone sealants is 12 months from the date of manufacture when stored in the original, unopened containers in a dry, ventilated area below 27°C (80°F). Storage in temperatures above 30°C for extended periods can accelerate chemical degradation, resulting in slower cure times, reduced physical strength, or product hardening within the cartridge.
