Technical Support & Application Engineering

SEMITI's technical support team supports customers through the qualification process and ongoing formulation work.

Technical support team:

Our Shanghai-based technical team includes: - Senior application chemists with paint, plastic, ink, and cosmetic experience - Materials science engineers with TiO2 surface chemistry background - Regional support specialists in major markets (India, Vietnam, EU, Brazil) - English-speaking primary; Chinese and Spanish secondary

Support scope:

Grade selection consultation: - Recommend SEMITI grades for your specific application - Map your competitor reference grade to our equivalent - Discuss formulation implications of substitution - Provide cost comparison analysis

Qualification support: - Lab batch design recommendations - Dispersion / application procedure guidance - Test protocol recommendations - Result interpretation and troubleshooting

Production-scale support: - Production trial planning - On-site visits where geographically feasible (Asia, EU major markets) - Color match support (for tinted paint, automotive) - Process optimization

Ongoing customer support: - Batch-to-batch consistency monitoring - Quality issue investigation - Formulation upgrades / cost-down projects - Multi-year supply planning

Response times:

• Email response: within 24 hours UTC+8 business days
• Technical inquiry response: 1–3 business days for standard, longer for complex
• On-site visit: 2–4 weeks lead time for scheduling

Cost:

Technical support is included with SEMITI supply — no separate fee for typical qualification and formulation support. For extensive co-development projects or on-site visits, we may discuss reimbursement of travel costs.

Communication channels:

• Email: [email protected] (primary)
• WhatsApp: +86 156 3910 0440 (fast response)
• WeChat: same number (for China-side coordination)
• Video meetings: Zoom, Teams, Google Meet supported

Technical knowledge base:

Our /learn section (30+ articles) covers fundamental TiO2 science, application engineering, regulations, and trade. Customers often start here before formal inquiry.

For complex applications:

For premium qualifications (automotive OEM, pharmaceutical excipient, cosmetic specialty), we engage with extended technical dialogue, sometimes including supplier-side technical specialists for production-process-level discussions.

Limitations:

We support TiO2-specific technical questions. Broader paint formulation, complete polymer recipe development, or general chemical industry consulting is outside our scope. We can refer customers to formulation consultants where appropriate.
