High Temperature Thermal Spray Sealants

Tech Bulletin A5-S3

Aremco's thermal spray sealers enhance the effectiveness and longevity of thermal spray coatings by penetrating their porous structure through capillary action. This process results in a smoother, denser surface, improving overall performance. These sealers are utilized across various industries, including aerospace, automotive, marine, and power generation. Aremco provides epoxy and phenolic sealers suitable for low-temperature applications up to 400°F (204°C), as well as silicone and ceramic sealers designed for high-temperature environments.
