Absorbent and protective composition containing an elastomeric copolymer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current masking and cleaning methods in the automobile, building, and aviation industries are time-consuming, expensive, and often damage surfaces, while also generating toxic fumes and hazardous waste, as they rely on traditional materials like masking tape and chemical solvents.
Innovation Solution
A liquid composition comprising an elastomeric copolymer dissolved in a solvent, which forms a protective film that can be easily applied, dries quickly, and is oleophilic, allowing it to absorb oil-based contaminants and prevent paint overspray, while being easily removable and safe for various surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If masking tape and paper are used to protect surfaces during painting operations, then paint overspray is prevented, but the process becomes time-consuming and labor-intensive
Solution Approach 1:
The patent replaces mechanical masking systems (tape and paper) with a chemical masking system consisting of a liquid composition that forms a protective film. This liquid composition contains polymers and additives that create a barrier against paint overspray without requiring physical application of tape or paper, thereby reducing the time and labor required for masking operations
Solution Approach 2:
The patent utilizes changes in the physical and chemical parameters of the masking material. The liquid composition transitions from a liquid state (easy to apply) to a film state (protective barrier) through controlled evaporation and curing. This parameter change allows the masking material to be applied quickly as a liquid while forming a durable protective film that prevents paint overspray
2Reliability
If chemical solvents are used to clean oil and grease from surfaces, then cleaning effectiveness is improved, but toxic fumes and hazardous waste are generated
Solution Approach 1:
The patent employs a masking composition that can be applied, used for its protective function, and then easily removed without leaving harmful residues. The composition is designed to be discarded after use rather than requiring complex disposal procedures, and it does not generate hazardous waste or toxic fumes during application or removal, thereby eliminating the harmful factors associated with traditional chemical solvents
Solution Approach 2:
The masking composition is formulated as a disposable, single-use product that is applied to surfaces, provides temporary protection during painting operations, and is then easily removed. This disposable approach eliminates the need for complex solvent systems that generate toxic fumes and hazardous waste, as the composition itself is non-hazardous and can be safely discarded
3Reliability
If traditional masking materials are used, then paint protection is achieved, but surface damage can occur during removal
Solution Approach 1:
The patent utilizes controlled changes in the physical parameters of the masking film during the removal process. The film is designed to transition from a strongly adhered state (during painting operations) to an easily removable state (after painting is complete). This is achieved through parameter changes such as temperature variation, solvent application, or mechanical flexibility that allow the film to be peeled off without damaging the underlying surface
Solution Approach 2:
The masking composition exhibits dynamic properties that change over time and under different conditions. The film becomes more flexible and easier to remove after the painting process is complete, allowing for clean removal without surface damage. This dynamic behavior ensures both effective paint protection during the painting operation and safe removal afterward
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition significantly reduces the time and cost of masking and cleaning processes, prevents surface damage, and minimizes exposure to toxic fumes and hazardous waste by forming a protective, absorbent film that can be peeled off without leaving residue.
Implementation Method 1
the elastomeric copolymer is oleophilic
Implementation Method 2
the composition is configured to dry after being applied to a surface, leaving an elastomeric copolymer film

AI summary
An improved composition for protecting a vehicle, building, or airplane surface that will be painted or mechanically processed. For example, certain regions of a vehicle, building, or airplane may be masked in accordance with the present disclosure to protect those regions from paint overspray. The composition produces a film which adheres well to a surface to be protected, with few or no pinholes. Additionally, the composition can absorb any oil or grease present on the surface which can eliminate the need for towels and chemical solvents that may create toxic fumes, hazardous waste, and flammable hazards. Further, the material can be removed easily from the surface after use by peeling the film layer away from the surface.
