Deformulation Analysis of an OTR Tire Sealant Through Advanced Analytical Techniques

Deformulation Analysis of an OTR Tire Sealant Through Advanced Analytical Techniques

Background & Client Challenge

A leading global manufacturer of heavy-duty industrial vehicles approached us with a critical supply chain and quality assurance challenge. The client relies heavily on high-performance Off-the-Road (OTR) tire sealants to prevent punctures and minimize downtime for vehicles operating in extreme mining and construction environments. However, the client was facing sudden performance variations from their incumbent supplier's sealant, which led to premature product drying and reduced sealing efficiency. Because the exact chemical formulation was a proprietary secret of the supplier, the client lacked the technical insights required to establish an internal quality benchmark, audit incoming batches, or source an equivalent alternative. They required a comprehensive deformulation analysis (reverse engineering) to decode the complex chemical blueprint of the high-performance sealant.

Our Solution

To achieve comprehensive formulation characterization, our experts developed a multi-technique analytical workflow integrating complementary spectroscopic and chromatographic approaches.

The analytical workflow included comprehensive sample preparation, preliminary inspection, instrumental optimization, spectral data acquisition, and cross-validation among multiple analytical platforms. By combining qualitative and semi-quantitative approaches, our team was able to reconstruct the formulation profile and determine the contribution of individual components.

Key Findings & Results

The deformulation analysis successfully identified the major components and functional additives within the OTR tire sealant formulation. The analysis revealed that the product primarily consisted of:

Through FTIR and NMR analysis, the primary organic structures were confirmed, while GC/MS enabled identification of specific low-level additives. EDS analysis further supported the presence of inorganic fillers and mineral-based components, providing a complete understanding of the formulation composition.

Value Delivered to the Client

Our deformulation report provided the client with actionable, high-value business intelligence:

• Supply Chain Independence: The client successfully neutralized the risk of single-source dependency by utilizing this exact chemical blueprint to evaluate alternative blending partners.
• Rigorous Quality Control: Armed with specific concentrations of key ingredients, the client established a foolproof incoming raw material inspection protocol to prevent future batch failures.
• Cost Optimization: Understanding the exact composition allowed the client to negotiate fairer pricing based on raw material market costs.
