We provide curtain wall sealant and structural sealant production line EPC solutions.
Weather-resistant sealants typically require the incorporation of substantial quantities of solid powders (such as carbon black or calcium carbonate) to achieve specific performance characteristics and desired coloration.
Triple-shaft multi-functional agitation: This system combines low-speed wall-scraping agitation with high-speed shear dispersion, enabling the rapid breakdown of powder agglomerates.
High-capacity design: To meet the high-volume demands of the weather-resistant sealant market, we offer large-capacity equipment ranging from 1,000L to 5,000L.
Automated filling: Integrated with a fully automated discharge and packaging system, the entire process—from mixing to final canning—is executed seamlessly in a single continuous workflow.

Structural adhesives have zero tolerance for air bubbles (even microscopic bubbles can lead to adhesive tearing under mechanical stress).
Ultra-high vacuum system: Ensures the mixing process is conducted under an extremely high vacuum, thereby completely eliminating air from the raw materials.
Precise kneading force: Utilizes dual-planetary paddles to deliver powerful, dead-zone-free agitation, ensuring that high-viscosity base materials and additives are blended uniformly at the molecular level.
Temperature control system: Since structural adhesive reactions are temperature-sensitive, our jacketed temperature control system maintains a temperature deviation of less than ±1°C.

We offer not only standalone machinery but are also dedicated to providing global clients with comprehensive turnkey production line solutions—an area in which we possess extensive experience, particularly within the Russian and Middle Eastern markets:
