    Product Detail

    The Polyvinyl alcohol-sodium silicate interior wall coating is a hybrid material that leverages the adhesive properties of polyvinyl alcoholand the thermal and mechanical strength enhancements provided by sodium silicate. This coating is known for its high transparency, thermostability, and mechanical strength. It is prepared via a sol-gel process, which allows for the creation of a highly viscous gel with an intricate polymeric network structure.

    Key Features:

    • Durability:The coating exhibits excellent durability, maintaining its state over time without fading or peeling.
    • Breathability:It contains moisture, allowing the coating to breathe and reducing the buildup of indoor humidity, which helps prevent mold and moisture-related issues.
    • Environmental Compatibility:The Polyvinyl alcohol-sodium silicate interior wall coating coating is low in volatile organic compounds (VOCs), making it a safe and environmentally friendly option.
    • Adhesion Strength:The strong chemical interaction between polyvinyl alcoholand silica results in improved adhesive strength, which is crucial for wall coatings.

    Applications:

    • Interior Wall Decoration:Mainly used for indoor wall decoration and protection, providing both aesthetic appeal and functional benefits.
    • Humidity Regulation:Effective in areas prone to high humidity, such as bathrooms and kitchens, where it helps prevent mold growth and moisture damage.

    Technical Specifications:

    • Chemical Interaction:The interaction between polyvinyl alcoholand silica is indicated by the weakening of the C-OH peak and the formation of a Si-O-C peak in XPS results, confirming the strong chemical bonding.
    • Thermal Stability:The silica/polyvinyl alcohol hybrid coating shows excellent thermal stability, with a significant enhancement in melting point and resistance to hygrothermal aging.
    • Mechanical Strength:The coating's mechanical strength is greatly improved due to the compatibility between polyvinyl alcoholand silica, with a notable increase in Young's modulus and ultimate tensile strength.

    Conclusion:

    Polyvinyl alcohol-sodium silicate interior wall coating is a high-performance, eco-friendly coating that offers excellent durability, breathability, and adhesion. Its unique combination of properties makes it suitable for a wide range of interior applications, from residential to commercial settings. The coating's ability to regulate humidity and resist mold, coupled with its enhanced mechanical and thermal properties, positions it as a leading product in the interior coatings market.
