Muyu Series Anti-Ablation Thermal Protection Coating
Product Overview
A sprayable ablative thermal protection coating for metal structural surfaces, curing at room temperature with controllable costs. Designed for short-duration extreme heat flux and long-duration open-flame protection. Available in two grades: SER-1A and PSER-8A.
Details & Technical Specifications
Series Positioning
The Muyu series is a sprayable, ablation-type thermal protection coating platform designed for metal structural components. It cures at room temperature via air spraying with controllable costs, making it ideal for short-duration extreme heat flux and long-duration open flame protection scenarios. Available for temperatures ranging from 700°C to 1300°C, it is compatible with aluminum, magnesium, and titanium alloy surfaces.

SER-1A Details
Uses a silicone-modified epoxy matrix, cures via room-temperature air spraying with controllable costs. After ablation, it forms a rigid carbonized shell without delamination or cracking; exhibits linear deformation of less than 2% following thermal shock at 300°C. Suitable for aluminum, magnesium, and titanium alloy surfaces in environments involving aerodynamic heating and high-temperature open flames.
PSER-8A Details
Utilizes a silicon carbide-reinforced phenyl silicone rubber matrix, cured via room-temperature air spraying. After ablation, it forms a SiCO ceramicized shell that withstands strong aerodynamic shear, instantaneous scouring, and moderate thermal shock. Suitable for aluminum, magnesium, and titanium alloy surfaces; designed for aerothermal heating and high-temperature open-flame environments.
