Low Melting Point Glass Powder Used In Building Materials

Application Scenarios 

Core Characteristics Of Low Melting Point Glass Powder

Technical Support & Advantage Description

Architectural Coatings (Exterior Wall/Floor)

1. Strong weather resistance & anti-aging: Low- melting point glass powder reflects UV rays, delays coating chalking and gloss loss, extending service life to over 15 years.

2. High wear & scratch resistance: Mohs hardness 6-7, improving wear resistance by more than 3 times and reducing scratches.

3. Optimized film-forming property: Fills pores, reduces water absorption, and prevents blistering and peeling.

Low-melting point glass powder ultra-fine particle size (≤5μm) ensures uniform dispersion and good compatibility with resins, suitable for spraying, rolling and other construction processes, especially for exterior walls in rainy and high-sunlight areas.

Cement-based Materials (Concrete/Mortar)

1. Enhanced mechanical properties: 20% dosage increases the 90-day compressive strength by 13.2% compared with the reference group, refining the pore structure.

2. Optimized durability: Improves sulfate corrosion resistance and inhibits alkali-aggregate reaction (ASR).

3. Eco-friendly & economical: Replaces less than 30% of cement, reducing costs and realizing solid waste utilization.

Particle size must be controlled at ≤75μm and dosage at ≤20%; pozzolanic activity generates hydration products with low calcium-silicon ratio, suitable for ultra-high performance concrete (UHPC) and other scenarios.

Wall Putty/Tile Adhesive

1. Enhanced adhesion: Reduces wall hollowing and chalking, improving the bonding strength between putty and substrate.

2. Impermeability & moisture resistance: Forms a dense structure, reduces water absorption, suitable for humid environments such as bathrooms and exterior walls.

3. Improved workability: Adjusts rheological properties, prevents sedimentation and enables easy sanding and leveling.

Low-melting point glass powder high chemical inertness and excellent compatibility with organic adhesives; can directly replace some traditional fillers such as ground calcium carbonate without affecting drying rate.

New Functional Building Materials (Fireproof Panels/Partition Panels)

1. Enhanced fire resistance: Melts above 600℃ to form a dense barrier layer, increasing fire resistance rating from 30min to 90min.

2. Optimized physical properties: Improves panel sound insulation and reduces overall density to achieve lightweight.

3. Dimensional stability: Low expansion coefficient, reducing cracking and deformation caused by temperature changes.

Low-melting glass powder is suitable for high-temperature pressing process of panels; inorganic components are non-combustible and aging-resistant, meeting green building material standards.

Artistic Decorative Coatings

1. Optical effect regulation: Achieves matte, pearlescent or textured effects through particle size differences.

2. Transparency retention: Refractive index matches that of resins (about 1.53), without affecting coating transparency.

3. Texture enhancement: Endows the paint film with fullness and a fine, smooth touch.

Transparent glass powder can be used with color pastes, suitable for scenarios requiring high visual effects such as interior wall artistic paint and antique brick finishes.
