Matte Golf Ball Paint Composition Color Scattering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golf balls face challenges in maintaining their original color due to color scattering during injection molding, and existing materials like urethane and surlyn have limitations in adhesion and abrasion resistance, especially with glossy finishes.
Innovation Solution
A matte golf ball paint composition incorporating an urethane-modified alkyd resin, a specific curing agent, and a silicon-based matting agent, along with a light stabilizer, is used to create a durable and matte finish that resists weathering, water, and yellowing, while maintaining the original color and improving performance metrics like driving distance and spin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a glossy color coating is applied on the surface of cavity dimples after injection molding, then the golf ball has high visibility and aesthetic appearance, but the original color of the cover is difficult to deliver due to color scattering with light reflection
Solution Approach 1:
The patent changes the surface finish parameter from glossy to matte by incorporating a matting agent in the clear coat composition. This matte finish reduces light reflection and scattering, allowing the original cover color to be visible while maintaining golf ball visibility through the inherent color of the cover material itself
Solution Approach 2:
The patent uses a multi-layer coating system where a clear matte coat is applied over a colored base layer. The clear matte coat acts as an intermediary that protects the base color while allowing it to show through, solving the color scattering problem by eliminating the glossy reflective surface
2Productivity
If urethane or surlyn materials are used for the golf ball cover, then driving distance and spin performance are improved, but adhesion and abrasion resistance with color paints are poor
Solution Approach 1:
The patent employs a composite coating system consisting of a colored base layer and a clear matte top coat. The base layer provides color and the top coat provides protective properties including adhesion and abrasion resistance, while the urethane or surlyn cover material maintains its performance characteristics for driving distance and spin
Solution Approach 2:
The patent applies different functional layers to different aspects of the golf ball surface: the colored base layer provides color and the clear matte top coat provides protection and matte finish. This localized functional division allows each layer to optimize its specific property without compromising the overall performance
3Manufacturing precision
If a matte finish is applied to prevent color scattering, then the original color of the cover is delivered, but the abrasion resistance and durability of the surface may be compromised
Solution Approach 1:
The patent creates a composite coating structure where a colored base layer is covered by a clear matte top coat. The clear coat provides the matte finish for color accuracy while also providing a protective layer that enhances abrasion resistance and durability, solving both requirements simultaneously
Solution Approach 2:
The patent changes the surface optical parameter to matte finish while maintaining or enhancing mechanical strength parameters through the use of a protective clear coat formulation that cures to provide both matte appearance and durable surface properties
