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. Sealers formulated from ceramic, epoxy, phenolic, silicone and urethanes, are suitable for applications from room temperature to 3000 °F (1650 °C).
