Decorated Glass With Silane Coating for Forming Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glass reinforcement methods, such as thermal and chemical tempering, limit the application of decorative coatings due to their impact on glass properties, and existing decorative coatings are compromised by these processes, leading to reduced mechanical strength and optical issues.
Innovation Solution
A combination of a decorative coating with a silane coating, such as tetraethoxysilane or 3-mercaptopropyltrimethoxysilane, applied on glass surfaces, along with optional particles and treatments like ion exchange or ion implantation, enhances mechanical strength while allowing decorative coatings to be applied before forming processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If thermal tempering is applied to reinforce glass, then mechanical strength increases, but decorative coatings are compromised and mechanical strength is reduced
Solution Approach 1:
The glass is tempered before applying the decorative coating, rather than after. This preliminary reinforcement ensures the glass has the required mechanical strength to withstand subsequent coating processes and handling, while the coating is applied to already-strengthened glass, preventing the coating from interfering with the tempering process
Solution Approach 2:
A primer layer is introduced as an intermediary between the glass surface and the decorative coating. This primer creates a stable bonding interface that allows the coating to adhere properly to the tempered glass without compromising the glass's mechanical properties or the coating's integrity
2Reliability
If decorative coating is applied before thermal tempering, then coating integrity is maintained, but the glass cannot be cut or formed after coating
Solution Approach 1:
The glass is tempered and cut/formed before the decorative coating is applied. This sequence allows all mechanical processing to be completed on the bare glass, after which the coating is applied to the finished shape, ensuring both coating integrity and manufacturing flexibility
3Strength
If chemical tempering with surface layer deposition is used, then compressive stress is generated, but decorative coating deposition is affected
Solution Approach 1:
The glass undergoes chemical tempering and surface layer deposition before the decorative coating is applied. This ensures the compressive stress is already established in the glass structure, and the decorative coating is applied to the chemically-tempered surface, avoiding interference with the stress-generating process

Function Achieved in This Case
The glass achieves high resistance to machining and bending without compromising decorative coatings, enabling various forming processes like cutting, bending, and maintaining optical properties.
Implementation Method 1
at least a second coating with at least one silane, selected from the group comprising tetraethoxysilane, 3-mercaptopropyltrimethoxysilane, 3-mercaptopropyltriethoxysilane, 3-glycidyloxypropyltrimethoxysilane, or a mixture thereof, deposited entirely or partially over said decorative coating
Implementation Method 2
The second approach involves exchanging ions in the glass with others from an external source, mainly by means of immersing the glass in baths containing metal salts
Implementation Method 3
ion implantation, physicochemical strengthening
