JY813 General Purpose Silicone Sealant

Product Advantage

Ultra-Fast Curing & Tack-Free Performance

With a surface dry time of just 0.1 hours (6 minutes), this sealant achieves tack-free status in record time, slashing project downtime and allowing for quick follow-up work. Its rapid crosslinking formula builds initial strength rapidly, enabling immediate handling of sealed components without compromising bond integrity.

Universal Adhesion Without Primers

Designed to bond seamlessly with glass, ceramic tiles, vitrified surfaces, engineered plastics, and most coated finishes, it eliminates the need for primers in 90% of applications. This not only simplifies the workflow but also reduces material costs and application time for both small repairs and large-scale projects.

Non-Sag & Wide Temperature Tolerance

The non-sag, high-viscosity formula ensures smooth application on vertical and overhead surfaces, preventing drips or deformation. It maintains consistent gunnability from +5°C to +40°C and retains flexibility between -40°C and +100°C, making it suitable for indoor, outdoor, and extreme-temperature environments.

Durable & Aging-Resistant Formulation

Resistant to yellowing, blackening, and UV degradation, the JY813 General Purpose Acetic-Curing Silicone Sealant retains its structural and aesthetic properties for years. It offers excellent tensile strength (0.49 MPa) and compression resistance, ensuring airtight, waterproof seals that withstand weathering and daily wear.

As a high-performance solution for construction, maintenance, and household sealing needs, the JY813 General Purpose Acetic-Curing Silicone Sealant has become a trusted choice for professionals and DIYers alike. This one-component, acetic-curing sealant combines rapid curing, superior adhesion, and long-lasting durability, making it adaptable to diverse substrates and environmental conditions. Below is a detailed, SEO-optimized breakdown of its core attributes, technical details, and practical usage.

Technical Parameters

Physical & Application Properties

Appearance: A fine, uniform paste free of bubbles, caking, gel particles, or undispersed precipitates, ensuring consistent extrusion and a professional finish.

Extrusion Rate: 480 ml/min (far exceeding the ≥80 ml/min requirement), enabling efficient, continuous application for large gaps or high-volume projects.

Sag Resistance: Zero sag on vertical surfaces (meets the ≤3 mm standard) and no deformation on horizontal substrates, ideal for precision sealing tasks.

Mechanical Performance Metrics

Hardness: 20 Shore A, balancing flexibility and structural support for dynamic joints that require movement accommodation.

Elongation at Break: 200%, allowing the sealant to stretch without cracking or losing adhesion, even as substrates expand or contract.

Tensile Modulus (23°C): Tensile strength of 0.49 MPa (exceeding the >0.4 MPa standard) with 0% destruction area, guaranteeing robust bond integrity.

Bonding & Durability Certifications

Stretching Adhesion: No bonding destruction in stress tests, ensuring long-term adhesion to diverse substrates without peeling or separation.

Compliance: Certified by IAF, CNAS, and SGS, validating its quality and performance for global construction and maintenance applications.

Product Uses

Construction & Building Sealing

Ideal for sealing gaps around door frames, window frames, suspended ceilings, and baseboards. It effectively seals joints in aluminum-plastic panels, glass curtain walls, and concrete structures, providing weatherproof and airtight protection against moisture and drafts.

Sanitary & Kitchen Applications

Perfect for sealing washbasins, bathtubs, toilets, and cisterns, as well as cooktops and shower room floors. Its waterproof and mold-resistant properties make it a top choice for wet environments, preventing leaks and maintaining hygiene.

Industrial & Transportation Sealing

Suitable for automotive, marine, and caravan sealing tasks, including glass-to-aluminum and aluminum-to-aluminum bonds. It works for general industrial bonding needs, such as sealing engineered plastics and coated metal components.

Household & DIY Repairs

Ideal for small-scale projects like sealing glass decor, fixing loose tiles, or repairing gaps in furniture. Its easy gunnability and fast curing make it accessible for DIY enthusiasts, while its professional-grade performance ensures long-lasting results.

Product Operate Guide

Pre-Application Preparation

Compatibility Check: Test adhesion on an inconspicuous area of the substrate to ensure compatibility, especially for sensitive materials.

Environment Setup: Work in temperatures between 4°C–40°C with relative humidity of 40%–80% for optimal curing.

Surface Cleaning: Remove dirt, grease, dust, and contaminants using a solvent-free cleaner. Allow porous substrates (e.g., concrete) to dry completely for 24 hours before application.

Application Steps

Tape Masking: Apply temporary protective tape along the edges of the sealing area to ensure clean, straight lines and easy cleanup.

Nozzle Trimming: Cut the nozzle at a 45° angle to match the gap size (nozzle diameter should be 1/2 the gap depth for full filling).

Sealant Extrusion: Load the cartridge into a caulking gun. Squeeze the trigger evenly to extrude a continuous, uniform bead. Move the gun slowly (5 cm/second) to avoid bubbles or gaps.

Post-Application Finishing

Smoothing: Use a silicone tool or damp finger to smooth the bead within 5–10 minutes of application, ensuring full contact with the substrate.

Tape Removal: Peel off the protective tape before the sealant cures (within 15 minutes) to prevent peeling.

Curing Period: Allow 24 hours for full curing. Avoid water exposure or physical stress during this period for maximum bond strength.
