Surface Dry Time: Only 0.1 hours (6 minutes), allowing for quick follow-up work and reducing project downtime.

Hardness: 25 Shore A (within the 20-60 range), balancing flexibility and structural stability.

Sag Resistance: Zero sag in vertical placement and no deformation in horizontal use, ensuring clean, even application on all surfaces.

Temperature Range: Maintains flexibility and performance from -40°C to 150°C, adapting to seasonal thermal changes and harsh environments.

Quality & Certification Compliance

Manufactured with high-grade environmental protection raw materials, the JY823 Excellent Silicone Sealant is free from cracking and yellowing over time. It passes rigorous quality tests, with a bonding destruction area of 0% and tensile modulus exceeding 0.4 Mpa, ensuring consistent, reliable results.

Product Uses

Construction-Specific Applications

Sealing and bonding glass windows, doors, and curtain wall panels for weatherproof and airtight protection.

Securing large flat glass, skylights, and sunrooms, preventing water infiltration and energy loss.

Sealing joints between glass and other materials (metal, wood, masonry) in architectural structures.

Repairing cracked glass surfaces in commercial buildings and residential properties.

Household Essential Uses

Sealing kitchen sinks, bathroom fixtures, and tiles to prevent water leakage and mold growth.

Bonding and sealing lubrication molds, fiberglass products, and aluminum surfaces.

Interior and exterior decorative projects, thanks to its customizable colors and weather-resistant design.

Product Operate Guide

Pre-Application Preparation

Confirm compatibility between the JY823 Excellent Silicone Sealant and the substrate material before use.

Work in a clean environment with temperatures between 4°C-40°C and relative humidity of 40%-80% for optimal adhesion.

Clean the substrate surface thoroughly to remove dirt, grease, and contaminants. Use a lint-free cloth with mineral spirits if needed, then let the surface dry completely.

Apply temporary protective tape along the edges of the application area to ensure clean, straight lines.

Application Steps

Cut the sealant nozzle at a 45-degree angle, ensuring the diameter is smaller than the thickness of the area to be sealed (nozzle should reach 1/2 the depth of the gap).

Extrude the sealant continuously to form a uniform, bubble-free cylinder. Move the gun slowly and steadily to fill the substrate interface completely—avoid rapid movements that cause holes.

Smooth the sealant surface immediately after application using a tool or gloved finger.

Remove the temporary protective tape before the sealant dries to achieve a neat finish.
