Overview
Thermal insulation mortar fireproof coating is a composite material designed to provide both thermal insulation and fire protection. It is commonly applied to building exteriors, walls, and structural components to enhance energy efficiency and comply with fire safety regulations. The coating typically consists of inorganic binders, lightweight aggregates, and fire-retardant additives. Its dual functionality makes it a cost-effective solution for modern construction, reducing the need for separate insulation and fireproofing systems. The material is favored for its ease of application, compatibility with various substrates, and long-term performance under harsh environmental conditions.
Physical and Chemical Properties
The coating exhibits low thermal conductivity (typically 0.05–0.1 W/m·K), ensuring effective heat retention. Its fire resistance is achieved through endothermic reactions and the formation of a protective char layer, which can withstand temperatures up to 1,000°C for 1–2 hours. Chemically, it is stable and non-reactive under normal conditions. The water-based formulations are environmentally friendly, with low VOC emissions. The material adheres well to concrete, metal, and masonry surfaces, and its lightweight nature minimizes structural load.
Main Applications
Primary uses include insulating and fireproofing exterior walls, roofs, and pipelines in residential, commercial, and industrial buildings. It is also applied in high-risk areas such as electrical rooms, stairwells, and HVAC ducts to prevent fire spread. In addition to new construction, the coating is used for retrofitting older buildings to meet updated fire codes. Its versatility extends to offshore platforms and tunnels, where both insulation and fire safety are critical.
Safety and Storage
The cured coating is non-toxic and safe for indoor use. However, during application, workers should wear masks and gloves to avoid inhalation or skin contact with uncured material. Proper ventilation is recommended. Storage requires protection from moisture and extreme temperatures. Unopened bags or containers have a shelf life of 6–12 months. Once mixed, the material should be used within 2–4 hours to prevent hardening.
B2B Procurement Guide
Bulk buyers should prioritize suppliers with certifications like ISO 9001 and fire safety compliance (e.g., EN 13501-1). Request samples to test adhesion and drying time. Prices vary based on fire resistance duration and insulation performance; negotiate volume discounts for orders exceeding 1 ton. Logistics considerations include moisture-proof packaging and timely delivery to prevent material degradation. Preferred suppliers often provide technical support for large-scale projects.
