TEP
Anionic Pretreatment Surfactant TEP is a high-performance, industrial-grade chemical additive with 96~100% purity. It boasts exceptional alkaline stability, strong penetration, emulsification, and oil removal capabilities, paired with reliable corrosion inhibition. Designed for pre-processing in textile, metal, and coating industries, it effectively cleans, degreases, and activates surfaces, ensuring optimal adhesion and uniformity for subsequent processes. This versatile surfactant maintains stability in high-temperature and harsh chemical environments, making it a trusted choice for industrial pretreatment needs.
Product Advantage
Outstanding Alkaline Stability: Maintains efficient performance in solutions with 100gNaOH/L, achieving penetration within ≤60s, ensuring consistent degreasing and cleaning in strong alkaline systems.
High Purity & Efficacy: With ≥98.2% content, it delivers powerful emulsification, oil removal, and wetting, significantly enhancing surface cleanliness and subsequent process adhesion.
Oxidation Resistance & Compatibility: Works well with oxidants like hydrogen peroxide and can be compounded with OEP-70/OASE for synergistic effects, suitable for diverse formulation needs.
Wide Applicability: Performs stably in high-temperature conditions, making it reliable for both textile scouring and metal surface pretreatment processes.
