Solution Overview

Problem

Existing methods for forming coatings with metal compounds and halogen-containing compounds often result in uneven and unstable films due to particle generation, making it difficult to achieve a uniform and stable coating.

Innovation Solution

Incorporating an amine compound into a coating-forming liquid composition containing a metal compound and/or a halogen-containing compound, specifically using a solution with metal elements from period 2 to 6 of the periodic table, to form a coating that is uniform and stable.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a liquid composition including metal compound and halogen-containing compound is applied to form coating, then the coating can be formed on substrate surface, but particles are generated from the composition components resulting in uneven coating thickness and low stability

Solution Approach 1:

An amine compound is introduced as an intermediary substance between the metal compound and halogen-containing compound. The amine compound acts as a complexing agent that binds to metal ions, preventing direct precipitation reactions between metal compounds and halogen-containing compounds, thereby eliminating particle generation and ensuring uniform coating formation with high stability

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The chemical environment parameters of the liquid composition are modified by adding the amine compound, which changes the coordination chemistry of the metal ions. This parameter change prevents unwanted precipitation reactions and maintains the stability of the coating components in solution, resulting in uniform and stable coating formation
