BST-INS-006IC -Aerogel Thermal Insulation Intermediate Coating For Building Interior Walls
BST-INS-006IC BST-INS-006IC is a water-based thermal insulation intermediate coating formulated with nano-SiO aerogel powder as the core component, supplemented by hollow glass microspheres, specialized emulsion, and functional additives through a proprietary process. Utilizing a multi-scale material system combining "micrometer-scale framework + nanoscale aerogel filling," it maintains over 90% porosity (with pore sizes ranging from 20 to 50 nm), creating an "infinite thermal insulation plate effect" that delivers exceptional thermal performance. Additionally, it integrates multiple functionalities including Class A1 fire resistance and sound insulation. Upon application, it forms a dense, uniform insulation layer; its 2 mm thickness is equivalent to that of 30 mm of conventional insulation material, reducing heat transfer by 90% and effectively lowering building energy consumption by 15–20%. As an intermediate product, it must be combined with a dedicated primer to form a complete coating system.
