AI Technical Summary

Benefits of technology

This patented technical solution described in this patents relates to improving fireproof coatings that resist contaminations while also having good environmental protection capabilities like moisture barrier or gas separation characteristics. These improvements include increased durability against pumping out liquids (fume), reduced surface temperatures at combustible surfaces, reducing volatile organics emissions during fires, increasing stability under extreme conditions, maintaining long term weatherworthiness, protecting metal components from damage due to lightning strikes, and modifying the composition of the paint before application without affecting its quality. Additionally, these solutions aim to enhance the overall function and lifespan of the painted product. Overall, they provide superior results over existing methods but offer unique benefits compared to other options.

Problems solved by technology

This patents describes how traditional methods for applying an Anti-Foam FlashOver Coat (AFC) onto surfaces contaminated with heavy metals like lead or mercury often result in cracks that allow harmful substances from these materials to enter into homes around them through gaps where there may be other objects nearby. These cracks make repairs difficult without damaging surrounding structures. Additionally, this method does little work because some particles stick out easily during use leading to reduced durability over time.
