Burst pressure testing for adhesive and coating performance evaluation
A cost-effective burst pressure testing setup for rapid screening of adhesive and coating performance using internal pressure and image analysis. It supports high throughput and automation, providing quantitative data on adhesive effectiveness with minimal labor.
Overview
The proposed burst pressure testing technology offers a novel approach to rapidly evaluate the performance of adhesives and coatings. By applying internal pressure to a substrate sealed with an adhesive, the system measures the pressure at which failure occurs, known as burst pressure. This method, coupled with advanced image analysis, provides detailed insights into adhesive effectiveness by mapping substrate and adhesive deformation over time. The cost-efficient system is designed for easy operation without specialized training and is scalable for automated, high throughput testing.
Technical specifications
Key features:
- Utilizes internal pressure to evaluate adhesive performance on defect-sealed substrates.
- Integrates image analysis tools to map deformation and quantify local strain.
- Supports a variety of substrates and adhesives, including pressure-sensitive adhesives (PSAs).
- High throughput capability with potential for automation, enabling over 50 tests per day with minimal labor.
- User-friendly GUI for rapid data collection and analysis, avoiding complex force-distance measurements.
Technology readiness level
The technology is currently at TRL 4, indicating that it has been validated in a laboratory environment. Future plans involve developing hardware for compatibility with various substrate sizes and deformability, refining testing protocols, and enhancing analytical tools to support reliable, automated testing procedures.
