Carboline Thermaline Range: Advanced Protection for High-Temperature Environments
The Carboline Thermaline range offers high-performance heat resistant coatings developed for extreme temperature applications across industrial sectors. Formulated for substrates exposed to high heat, thermal shock, and chemical exposure, these coatings provide long-lasting durability and structural protection. Ideal for exhaust systems, process equipment, and insulated surfaces, Thermaline ensures high-temperature performance where reliability is critical.
The range includes both single- and multi-component options featuring epoxy and silicone chemistries. Thermaline coatings are engineered for use in applications reaching temperatures up to 650°C, with specific products suitable for cryogenic cycling and under insulation (CUI) conditions. Designed to prevent blistering, peeling, and corrosion, these coatings extend maintenance intervals and reduce unplanned downtime. Thermaline supports operational safety, efficient application, and compliance in power, refining, and chemical processing facilities, providing confidence in the most challenging conditions.
Carboline FAQs
What temperature ranges can Carboline Thermaline coatings handle?
Carboline Thermaline coatings cover a wide temperature spectrum, with certain products suitable for continuous service at temperatures up to 650°C. Some formulations are also resistant to intermittent spikes beyond this range and are tailored to specific service environments.
Are Thermaline coatings effective in cryogenic or thermal cycling conditions?
Yes, selected Thermaline products are specifically designed to perform under severe thermal cycling, including cryogenic conditions. These coatings maintain adhesion and film integrity during rapid temperature changes, making them ideal for dynamic process systems.
Can Thermaline be applied to surfaces without shutting down operations?
Many Thermaline coatings can be applied to hot surfaces, helping reduce the need for costly operational shutdowns. However, each product has defined limits for surface temperature during application—always consult the technical datasheet for accurate parameters.
Is the range suitable for use under insulation?
Thermaline includes coatings specifically developed for CUI protection. These formulations resist moisture ingress and thermal degradation under insulation, offering long-term corrosion control in high-humidity or condensate-prone environments.
What surface preparation is required before application?
Proper surface preparation is essential for optimal performance. This typically involves abrasive blasting to a specified cleanliness and profile. The exact requirements vary by product and service condition, so always refer to Carboline’s surface prep standards in the relevant datasheet.
