DTI TC200 is an organic-inorganic hybrid sol-gel coating designed specifically for shell-and-tube heat exchangers operating in demanding high-temperature environments. This transparent, 3-6 μm coating provides exceptional fouling resistance and corrosion protection while maintaining optimal heat transfer characteristics.
Engineered for continuous operation up to 662°F (350°C) with short-term exposure capability to 752°F (400°C), TC200® delivers low surface energy properties (<30 mN/m) that significantly reduce deposit adhesion in crude oil processing, FCC reactor systems, and high-temperature heat exchanger applications.
High-temperature fouling in shell-and-tube heat exchangers represents a persistent challenge across petroleum refining and petrochemical processing. Conventional surface treatments often fail under extreme thermal conditions, leading to frequent maintenance cycles and operational disruptions. Thermal cycling degradation of conventional coatings. Substrate adhesion failures under thermal stress
Coating Integrity Breakdown Threshold
DTI TC200’s hybrid sol-gel technology addresses these challenges through its unique organic-inorganic composition, providing exceptional thermal stability while maintaining low surface energy characteristics essential for fouling mitigation. Surface energy maintained at <30 mN/m after high-temperature exposure. Perfect adhesion rating across multiple substrates. 1000-hour crude oil exposure validation
Thermal stability during continuous operation
Reduce deposit adhesion through maintained low surface energy properties even after extended high-temperature exposure, enabling longer operational periods between maintenance cycles.
Withstand continuous operation at 662°F with short-term exposure capability to 752°F, ensuring coating integrity during normal operating conditions and thermal cycling events.
Provide excellent chemical resistance including 37% hydrochloric acid exposure and extended immersion in aggressive environments without coating degradation.
Achieve superior adhesion across carbon steel, stainless steel, and aluminum substrates with appropriate surface preparation protocols. Applicable on new fabricator or existing equipment.
Maintains properties that preserve heat transfer characteristics while providing superior fouling resistance.
Extend equipment operational uptime through reduced fouling accumulation and enhanced resistance to acid attack in corrosive process environments.
