Reviewer 1 Report
This paper reports an investigation on synthesis and characterization of tannin-epoxidized soybean oil as bio-based resin to replace phenol-formaldehyde (PF) resin and fabricate biobased grinding wheels.
Epoxidized soybean oil and tannin originating from agricultural sources and 1,6-hexanediamine as a cross-linking agent were reacted together to obtain TEH resin. Then TEH was mixed wood powder, coffee powder and walnut powder, with these mixtures grinding wheels were prepared.
Synthesis is rather simple. Materials were characterized by FTIR and electrospray ionization (ESI).
The appearance, hardness, compressive strength and wear resistance of the resulting biobased grinding wheels were studied. It was shown that they have smooth surface, and hardness and wear resistance were greater than that of phenolic resin based grinding wheels.
In my opinion, this paper can be accepted for publication in Polymers with minor revisions.
Figure 2, Figure 4and Figure 7 should be magnified, it was difficult for me to read them without zooming
In the caption of Figure1 Figure 2and Figure 3 please use THE instead of THE
Please add a Table to explain differences in S1, S2, S3, S4

- Figure 2, Figure 4and Figure 7 should be magnified, it was difficult for me to read them without zooming。
Reply to reviewer: Thank the reviewers for their comments. We have re-edited Figure 2, Figure 4 and Figure 7, which should meet your requirements now.
- In the caption of Figure1 Figure 2and Figure 3 please use TEH instead of THE
Reply to reviewer: I revise it and mark it with yellow highlighting.
- Please add a Table to explain differences in S1, S2, S3, S4
Reply to reviewer: I added Table 1 to distinguish S1-4 in the article.
Reviewer 2 Report
The work is very interesting. The topic is very timely due to the reference to natural resources and renewable biomass. In addition, the obtained results are very promising. Therefore, I request the publication of the article after a few minor graphic corrections:
- in Fig. 4 showing SEM photos, the S1-S4 markings are not very legible. Please change the color, e.g. to white or black.
- Figures 5 and 6 are hard to read. Please enlarge the font of the legend, and in the case of Fig. 5 change one of the colors to a less bright one.
