Hanshi 919 Stone Interface Back Glue Sealant: An Efficient Choice for Enhancing Tile Adhesion Strength

I. Common Issues in Stone and Tile Adhesion

Hollowing and detachment are common problems during stone and tile installations, especially with tiles treated with release agents, which hinder proper bonding. These issues can compromise the quality and safety of the installation.

Hanshi 919 Stone Interface Back Glue Sealant addresses these challenges through its innovative small molecular structure and hydrophilic groups, which significantly enhance adhesion and provide excellent waterproofing​​.

II. Unique Features of Hanshi 919

1. Interface Bridging Function: The molecular structure of Hanshi 919 penetrates the release agent layer, creating a bridging interface that strengthens adhesion.
2. Superior Bonding Strength: Hydrophilic groups in the sealant react with cement silicates, forming strong bonds that greatly enhance adhesion​.
3. Waterproof and Anti-Alkaline: Hanshi 919 effectively prevents moisture infiltration and resists alkaline substances, reducing the risks of hollowing and cracking​.
4. Simplified Application: It is a single-component product, ready to use without mixing, which improves efficiency and minimizes material waste​.

III. Application Scenarios

1. Tiles Treated with Release Agents: Hanshi 919 solves bonding issues where conventional adhesives fail, providing reliable adhesion​.
2. High-Humidity Environments: Ideal for pools and bathrooms, it ensures long-lasting adhesion and waterproof performance.
