JY913 Multi-Purpose Neutral Silicone Sealant

Product Advantage

Neutral-Curing & Non-Corrosive Safety

Unlike acidic sealants, it cures without releasing corrosive byproducts, making it safe for marble, granite, stainless steel, and aluminum. It won’t stain or damage sensitive surfaces, ideal for luxury renovations and high-end commercial spaces.

UV-Resistant & Weatherproof Durability

Infused with advanced UV stabilizers, it withstands prolonged sunlight exposure without fading, cracking, or aging. It excels in outdoor applications, providing weatherproof sealing against rain, wind, and temperature fluctuations (-40°C to +100°C).

Fast Drying & High Efficiency

With a surface dry time of 0.7 hours (42 minutes) and full curing in 24 hours, it accelerates project timelines. The quick-dry formula reduces downtime, allowing for faster follow-up work and project completion.

Superior Bonding & Flexibility

Boasting a tensile strength of 0.79 MPa and elongation at break of 267%, it offers exceptional structural support and flexibility. It accommodates substrate movement (e.g., thermal expansion) without losing adhesion, ensuring durable, long-lasting seals.

Non-Toxic & Low-Odor Formula

Free of harmful toxins and low in odor, it is safe for indoor use in kitchens, bedrooms, and children’s spaces. Its family-friendly formulation meets global safety standards, making it suitable for residential and commercial environments.

The JY913 Multi-Purpose Neutral-Curing Silicone Sealant is a premium, non-corrosive solution designed for demanding sealing tasks across residential, commercial, and industrial settings. Its neutral-curing formula ensures safety for sensitive substrates, while its UV resistance, fast drying, and superior adhesion make it a versatile choice for indoor and outdoor applications. Below is a comprehensive SEO-optimized guide to its features and usage.

Technical Parameters

Physical & Application Properties

Appearance: A smooth, uniform paste available in 80+ colors (including white, transparent, and custom shades). It is free of bubbles, lumps, or undispersed particles.

Sag Resistance: Zero sag on vertical surfaces and no deformation on horizontal substrates, guaranteeing neat, professional results.

Mechanical Performance Metrics

Hardness: 40 Shore A, striking a balance between rigidity and flexibility for both static and dynamic joints.

Elongation at Break: 267%, allowing the sealant to stretch significantly without cracking or peeling.

Tensile Modulus (23°C): Tensile strength of 0.79 MPa (well above the >0.4 MPa standard) with 0% destruction area, ensuring robust bonding.

Quality & Safety Certifications

Stretching Adhesion: No bonding destruction in stress tests, validating long-term adhesion to diverse substrates.

Certifications: Approved by IAF, SGS, and CCMSA, meeting global quality and safety standards for construction and industrial use.

Product Uses

Building & Construction Sealing

Perfect for weather-proof sealing of glass curtain walls, aluminum plate joints, and door/window frames. It seals gaps in bricks, tiles, and concrete, providing airtight and waterproof protection against the elements.

High-End Interior Renovations

Ideal for sealing marble/granite countertops, bathroom fixtures (bathtubs, sinks, toilets), and decorative metal components. Its non-corrosive formula preserves the integrity of luxury materials, making it a top choice for hotels and luxury homes.

Industrial & Specialized Sealing

Suitable for PVC pipe joints, HVAC systems, and automotive components. It works for marine and caravan sealing tasks, offering corrosion-resistant and water-tight bonds in harsh environments.

Sensitive Substrate Applications

Safe for use on stainless steel, coated metals, and delicate plastics. It is ideal for commercial spaces (offices, retail stores) and projects requiring non-damaging sealing solutions.

Product Operate Guide

Pre-Application Preparation

Compatibility Testing: Apply a small amount of sealant to an inconspicuous area and cure for 24 hours to check adhesion and avoid staining (critical for marble/granite).

Environment Control: Work in temperatures of 4°C–40°C with relative humidity of 40%–80%. Avoid rainy or extremely humid conditions.

Surface Preparation: Clean substrates with a non-abrasive cleaner to remove dirt, grease, and oil. Allow porous materials to dry for 24 hours before application.

Application Process

Tape Masking: Use temporary protective tape to cover adjacent surfaces, ensuring clean edges and minimizing cleanup.

Nozzle Cutting: Trim the nozzle at a 45° angle to match the gap size (nozzle diameter = 1/2 gap depth for full filling).

Sealant Extrusion: Load the cartridge into a caulking gun. Squeeze evenly to extrude a continuous bead. Move the gun steadily to avoid air pockets, ensuring the gap is fully filled.

Post-Application Care

Smoothing: Smooth the bead with a silicone tool or damp finger within 10 minutes of application for a professional finish.

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

Curing Time: Allow 24 hours for full curing. Avoid water exposure for 6 hours and physical stress for 24 hours to ensure maximum strength.
