Initial Gloss vs. Long-Term Performance: The Truth About Resin Pads
1.Purpose of the Test
The objective of this study is to investigate and compare the differences between resin pads containing chemical active compounds and those relying solely on mechanical polishing. The test aims to determine which type of resin pad retains gloss and clarity for a longer period.
2. Test Preparation
2.1. Surface Condition: The floor was prepared using identical 200# resin pads to ensure consistency in testing conditions.
After completing the surface treatment, the prepared area was divided into three sections using adhesive tape. Each section was allocated for testing with one of the three groups of resin pads.
2.2. Test Subjects: The experiment was conducted on three group of resin pads:
|
Group A |
A brand of resin pads containing chemical active compounds. |
|
Group B |
Ashine resin pads. |
|
Group C |
A brand of resin pads without any chemical active compounds. |
3. The First Round of Testing
After polishing with 400# and 800# resin pads, data was collected from 9 points of gloss (GU) and clarity (DOI) for each group. This comprehensive sampling provided the basis for the following conclusions regarding the performance of each type of resin pad.
For each group, the results obtained from nine points were refined by removing the highest and lowest values. The average of the remaining data points was then calculated to minimize the impact of outliers and reduce errors in the final results.

Based on the results, Group A demonstrates the highest average values for both GU (57.2) and DOI (80.3) among the three groups. This indicates that Group A's resin pads are the most effective in retaining both surface gloss (GU) and clarity (DOI), showcasing superior overall performance in these metrics compared to Group B and Group C.
Next, we will calculate the standard deviation (SD) and coefficient of variation (CV) for these data.
SD = √(Σ(xi - x̄)² / n)
CV = (SD / x̄) × 100%
CV is the ratio of the standard deviation to the mean and is commonly used to compare the relative volatility of data across different scales or units. A higher CV indicates lower stability, while a lower CV reflects better stability.

Based on the results for the coefficient of variation (CV) in both GU and DOI, Group B (Ashine resin pad) demonstrates the best stability. Its CV values are the lowest among the three groups for both GU and DOI:
- GU Stability: Group B has a CV of 3.24%, lower than Group A (4.72%) and Group C (8.01%).
- DOI Stability: Group B has a CV of 1.53%, also lower than Group A (1.77%) and Group C (3.03%).
This indicates that Group B maintains surface gloss and clarity more consistently compared to the other two groups.
4. The Second Round of Testing
We conducted weekly maintenance on the three test areas using a single-head machine and a 3M 5100 Red Pad. After 50 days, a second round of data collection was performed to evaluate the performance of each test group.

Based on the data results, it is evident that after 7 weeks of regular maintenance, both the gloss (GU) and clarity (DOI) of the flooring decreased. However, the decline for Group A was significantly more pronounced compared to the other two groups, with a reduction of 63.7% in GU and 64.6% in DOI. Group B demonstrated the best stability, with reductions of only 17.9% in GU and 17.8% in DOI. Group C also showed moderate stability, with a 22.6% decrease in GU and a 16.9% decrease in DOI, performing better than Group A but less consistently than Group B.
5. Conclusion
It can be observed that although Group A (a brand of resin pads containing chemical active compounds) achieved higher GU and DOI values in the first round of testing, its operational stability was still inferior to that of Group B (Ashine resin pads). After 50 days, the chemical active compounds in Group A’s products failed to maintain adequate levels of gloss and clarity. Furthermore, these products not only pose risks to human health but also cause significant damage to the flooring.
Both Group B and Group C (a brand of resin pads without chemical active compounds) rely solely on mechanical polishing, and their performance remains excellent after 50 days. Among them, Group B stands out with superior stability and performance values, demonstrating its effectiveness in maintaining both gloss and clarity over time without relying on chemical active compounds.
