Import 511 Acetic General Purpose Silicone Sealant — Buy in wholesale FOB from Supplier in China

Foshan Gaojian 511 Acetic General Purpose Silicone Sealant is a one-part, room temperature acetoxy-cure silicone formulated for glazing, sealing and general construction bonding applications. The material cures at ambient conditions through reaction with atmospheric moisture, releasing acetic acid as a by-product during the cross-linking process. It demonstrates adhesion to glass, ceramics, aluminium and typical building substrates, with stated resistance to weathering and water ingress after full cure. The product is positioned for auto windscreen installation, window panel glazing, and repair of general building materials where a flexible, durable seal is required.

As an acetoxy silicone, the 511 contains acetic acid as the cure by-product, which produces a characteristic vinegar odour during application and initial cure. This chemistry typically achieves faster tack-free times and stronger initial bond development than neutral-cure alternatives, though it may cause corrosion on sensitive metals such as copper, brass or unpassivated steel unless specifically formulated otherwise. The sealant's movement capability, shore A hardness, and tensile strength at break are not stated in the source data, but are standard parameters for classifying general purpose silicone sealants in accordance with ISO 11600 or ASTM C920 building sealant standards. Typical acetic GP silicones in this category offer 25-50 percent movement capability and shore A hardness in the 15-35 range.

The primary buyers for this product are glazing contractors, automotive aftermarket windscreen installers, hardware distributors and construction material wholesalers. The acetic cure system makes it particularly suitable for non-porous substrates like glass and glazed ceramics where rapid skin formation and early water resistance accelerate project schedules. Buyers should confirm with Foshan Gaojian whether the 511 formulation contains fungicidal additives for high-humidity applications, as this specification is not disclosed. The supplier is located in Foshan, Guangdong Province, with no response rate data currently available.

Foshan Gaojian Silicone Sealant Industrial Co. Ltd operates from Wufuwei, Pingzhou, Foshan, in Guangdong Province, China, with the postal code 313001 listed in its address record. The company holds a harbour trust tier classification within the marketplace framework and markets the 511 Acetic General Purpose Silicone Sealant as a core construction chemical product. No response rate or average response hour data is available, which means communication reliability and quotation turnaround must be established through direct enquiry rather than platform metrics.

The supplier profile does not disclose manufacturing floor space, annual output capacity, number of employees, year of establishment, export licence status, or quality certifications such as ISO 9001. There is no mention of in-house R and D, laboratory testing capabilities, or third-party accreditation to standards such as ASTM C920, ISO 11600, or GB/T 14683. Buyers should request business licence copies, factory audit reports, and product test certificates before committing to volume orders. The Foshan location places the company within China's silicone manufacturing corridor, but trading company versus manufacturer status requires verification.
