Common Causes of NBR Latex Coagulation and How to Prevent It

Introduction

Coagulation is one of  issues in NBR latex applications. It can disrupt production, reduce product quality, and increase operational costs. Understanding the root causes is essential for prevention.

Main Causes of Coagulation

1. Poor Mechanical Stability
Latex exposed to shear forces may break down if stability is insufficient, leading to particle aggregation.

2. Contamination
Impurities such as metal ions or dust can destabilize latex systems and trigger coagulation.

3. Temperature Fluctuation
Higher temperatures accelerate chemical activity and increase the risk of instability.

4. Improper Storage
Extended storage time or inconsistent conditions can degrade latex properties over time.

Prevention Methods

• Use latex with high stability
• Maintain clean production systems
• Control storage temperature and environment

Conclusion

Preventing coagulation starts with both material selection and proper handling. Stable latex ensures smoother production and fewer defects.
