 Epoxy River table


The artistic resin River table is really pleasing to the eye, which is mostly made by resin infusion process. Most resin River tables are usually made of epoxy resin, and few are made of unsaturated resin based on cost considerations.


First of all, epoxy resin And Unsaturated resin Performance difference of


  • The epoxy resin with high curing rate and high yellowing rate usually needs to be cured for more than 24 hours, but the epoxy resin with high yellowing resistance needs to be cured for 5 hours.

  • Unsaturated polyester resin The curing speed of epoxy resin is 20 minutes, the curing speed is lower than that of epoxy resin, the curing time is less than 20 hours, and the curing time is about 2 hours.


Why is it that epoxy resin is widely used for the river table? Although the unsaturated resin curing fast, the potential risk is relatively brittle, in the absence of reinforced materials, the resin thick layer is very easy to crack. Most unsaturated resin gels are even exothermic when the peak temperature exceeds 150 ℃, which is also a potential hazard.


 Resin cracking


Another problem is the difference in bond strength. If you look at the figure below, even if the bonding force of ordinary epoxy resin is still weak, unsaturated resin is even less suitable for the situation without reinforcement around.

Which epoxy resin is more suitable for the production of resin River table?


Ordinary epoxy resin can, but usually can not get higher appearance and performance. The optimum epoxy resin for river table should be the modified epoxy resin with slow heat release and high weather resistance.
