Removable Moisture Barrier Composition for Clean Surface Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing moistureproofing methods lack the ability to provide effective, removable barriers that can be applied selectively and removed without causing significant damage to the surface, particularly in construction applications.
Innovation Solution
Formulations of polymer resin and curing agent chemistries are used to create a one-part, high-performance removable moisture barrier that can be applied via brushing, rolling, caulking, troweling, or spraying, and can be cured by exposure to moisture, allowing for easy removal when no longer needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If a moisture barrier is permanently applied to provide long term protection, then protection duration is improved, but removability deteriorates
Solution Approach 1:
The moisture barrier composition is designed to dynamically change its adhesion properties over time. Initially, it provides strong adhesion for permanent protection, but over time the bond weakens allowing for easy removal. This dynamic behavior resolves the contradiction between providing long-term protection and enabling easy removal when needed.
Solution Approach 2:
The composition undergoes parameter changes in its chemical structure and physical properties over time. The polymer resin and curing agent chemistry are formulated to change the bond strength parameter gradually, transitioning from strong initial adhesion to weaker later adhesion, enabling both long-term protection and easy removability.
2Strength
If a moisture barrier is applied to provide robust protection against moisture damage, then protection strength is improved, but damage to the surface during removal worsens
Solution Approach 1:
The composition acts as an intermediary layer between the moisture barrier function and the surface. It provides strong protection when applied but is designed to remove cleanly without damaging the underlying surface. The polymer resin and curing agent chemistry create a bond that is strong enough for protection but can be broken without harming the surface.
Solution Approach 2:
The moisture barrier composition is designed as a disposable protective layer that can be applied and then removed without causing harm. It provides robust protection during its service life and can be easily discarded or removed when no longer needed, leaving the surface intact.
3Ease of operation
If a moisture barrier is designed to be easily removable, then removability is improved, but adhesion strength deteriorates
Solution Approach 1:
The adhesion strength is designed to be dynamic rather than static. It provides strong adhesion initially to ensure good bonding, then gradually weakens over time to enable easy removal. This dynamic adhesion behavior resolves the contradiction between strong initial bonding and easy removability.
Solution Approach 2:
The composition is pre-formulated with polymer resin and curing agent chemistries that are designed to create a bond that will naturally weaken over time. The preliminary chemical formulation includes components that facilitate both strong initial adhesion and subsequent easy removal without requiring additional actions.
4Ease of manufacture
If a one-part composition is used to simplify application, then ease of manufacture is improved, but formulation complexity worsens
Solution Approach 1:
The polymer resin and curing agent are merged into a single unified composition that can be applied in one step. This combining of components simplifies the application process while the internal chemistry remains complex to provide the desired moisture barrier properties and removability characteristics.
