Matte Surface Coating for Fingerprint Resistance in Decorative Laminates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High pressure decorative laminates are susceptible to fingerprint buildup on their surfaces, which existing chemically modified surfaces have not effectively addressed.
Innovation Solution
A surfacing material with a matte finish is created by applying an electron beam radiation curable epoxy acrylic or urethane acrylic coating to the substrate, which is then UV-irradiated to crosslink only on the surface and subsequently electron beam irradiated and thermally cured to form a micro-convolution effect, reducing fingerprint visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional smooth glossy surfaces are used for decorative laminates, then aesthetic appearance is improved, but fingerprint buildup susceptibility worsens
Solution Approach 1:
The patent applies a matte finish coating that changes the surface optical properties from glossy to matte, which diffuses light and prevents fingerprint visibility while maintaining aesthetic appeal. This transforms the surface appearance to eliminate the harmful effect of fingerprint buildup.
Solution Approach 2:
The patent modifies the surface parameters by applying a coating with specific micro-convolution characteristics (Ra 0.2-2.0 micrometers) that changes the surface topology. This parameter change creates a texture that masks fingerprints while preserving the decorative laminate's aesthetic qualities.
2Object-affected harmful factors
If chemically modified surfaces are applied to reduce fingerprints, then fingerprint resistance is improved, but manufacturing complexity worsens
Solution Approach 1:
The patent uses a practical, cost-effective coating application process that can be integrated into existing manufacturing lines. The matte finish coating is applied as a relatively simple post-processing step compared to complex chemical surface modifications, providing fingerprint resistance without excessive manufacturing complexity.
3Object-affected harmful factors
If deeply sculpted and embossed surfaces are used, then fingerprint visibility is reduced, but manufacturing precision requirements worsen
Solution Approach 1:
The patent applies a matte finish coating with controlled micro-convolution characteristics (Ra 0.2-2.0 micrometers) that provides fingerprint masking at the micro-scale surface level without requiring deep macro-scale embossing. This local quality change achieves fingerprint resistance with moderate manufacturing precision requirements.
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 solution results in a decorative laminate with a matte surface that is resistant to fingerprint buildup, maintaining a clean and clear appearance despite regular use.
Implementation Method 1
The epoxy acrylic or urethane acrylic is irradiated with UV-radiation produce a UV-irradiated layer wherein the epoxy acrylic or urethane acrylic is only crosslinked on the surface thereof
Implementation Method 2
The UV-irradiated layer is then subjected to an electron beam irradiation to crosslink and harden the entire layer

AI summary
A surfacing material includes a substrate having a top side and a bottom side. A matte surface is formed on the bottom side thereof, wherein the matte surface of the surfacing material is a coating of an electron beam radiation curable material applied to the bottom side of the substrate. The coating is an epoxy acrylic or urethane acrylic laid upon the substrate. The epoxy acrylic or urethane acrylic is irradiated with UV-radiation to produce a UV-radiation layer wherein the epoxy acrylic or urethane acrylic is neither hardened nor is an entire layer of the epoxy acrylic or urethane acrylic crosslinked but rather the epoxy acrylic or urethane acrylic only crosslinked on the surface thereof, which produces a matting surface through the effects of a micro-convolution.
