In the field of stone processing and application, Veropoxy has successfully improved the comprehensive performance of stone products with its in-depth research and innovative application of epoxy resin, injecting new vitality into the development of the stone industry. This article will discuss in detail the application of epoxy resin on stone and how to cleverly use epoxy resin to improve the performance of stone products.
Epoxy Resin
Characteristics and advantages of epoxy resin
Epoxy resin is a high molecular polymer with many excellent properties, making it an ideal material for stone processing and protection. First of all, epoxy resin has extremely high bonding strength and can form a strong bond with the surface of stone, effectively preventing the cracking and falling of stone. Secondly, epoxy resin has good penetration performance and can penetrate into the tiny cracks of stone, fill and reinforce it, and enhance the integrity of the stone. In addition, the colloid shrinkage rate of epoxy resin is low, and the glue surface will not be concave after polishing, ensuring the flatness and beauty of the stone surface.
Compared with traditional unsaturated resins, epoxy resin has obvious advantages in stone repair and enhancement. Although unsaturated resin cures quickly, its bonding strength and moisture resistance are relatively poor, which can easily cause cracking and damage to the stone during use. Epoxy resin can maintain stable performance in various environments and provide long-term protection for the stone.
Application of epoxy resin in stone repair
(1) Repair of fine cracks
During the mining, transportation and processing of stone, some fine cracks are inevitable. These cracks not only affect the beauty of the stone, but may also become a hidden danger of stone damage. The high permeability of epoxy resin enables it to penetrate into these tiny cracks, fill them up, and restore the integrity of the stone.
During the repair process, the surface of the stone needs to be cleaned first to remove dust and impurities in the cracks, and then the epoxy resin is evenly applied to the cracks to allow it to fully penetrate. After a period of curing, the epoxy resin will form a whole with the stone, the cracks will no longer be obvious, and the strength and durability of the stone will also be significantly improved.
(2) Repair of large-area damage
Epoxy resin can also play an important role in some large-area damage on stone. By mixing epoxy resin with an appropriate amount of filler, a repair material with high strength and toughness can be made. When repairing, first grind the edges of the damaged part to make its surface rough so that the epoxy resin can adhere better.
Then fill the damaged part with the prepared epoxy resin repair material and smooth it with a scraper to make it flush with the surface of the stone. After the epoxy resin is completely cured, grind and polish it to restore the smooth surface of the repaired stone and integrate it with the undamaged part, with almost no trace of repair.
Application of epoxy resin in stone reinforcement
(1) Reinforcement of the back of the stone
In order to prevent the stone from breaking and breaking during use, epoxy resin can be used as stone back glue and applied on the back of the stone. Compared with traditional back glue materials, epoxy resin has better adhesion and permeability, can penetrate into the interior of the stone, and form a strong bond with the stone.
During construction, apply epoxy resin evenly on the back of the stone, then attach the backing net. After it solidifies, a solid protective layer is formed on the back of the stone. This protective layer can not only enhance the strength of the stone, but also effectively prevent the intrusion of moisture and harmful substances, extending the service life of the stone.
(2) Protective coating on the surface of stone
Epoxy resin can also be used as a protective coating on the surface of stone to provide all-round protection for the stone. This protective coating has excellent weather resistance, chemical resistance and wear resistance, can resist the erosion of the external environment, and maintain the color and texture of the stone.
During construction, first clean and dry the surface of the stone, and then evenly apply the epoxy resin protective coating on the surface of the stone to form a uniform film. After curing, this film will be tightly attached to the surface of the stone, forming a solid line of defense to prevent the stone from being polluted, worn and weathered.

Modification and innovation of epoxy resin
Although epoxy resin itself has many excellent properties, in order to better meet the needs of stone processing and application, Veropoxy continues to modify and innovate epoxy resin to further improve its performance.
(1) Optimization of curing speed
The traditional epoxy resin has a slow curing speed, which affects the efficiency of stone processing to a certain extent. In order to improve the curing speed, researchers have successfully shortened the curing time of epoxy resin to a few hours or even shorter by introducing special curing agents and accelerators. This fast-curing epoxy resin can greatly save time and improve production efficiency in the process of stone repair and enhancement, while also reducing the construction inconvenience and quality instability caused by long curing time.
(2) Enhancement of flexibility
Stone may be subjected to various external forces during use, such as impact, bending, etc., which requires epoxy resin to have a certain flexibility to adapt to the deformation of the stone without brittle cracking. By introducing flexible segments or adding toughening agents into epoxy resin, the flexibility of epoxy resin can be effectively improved.
The modified epoxy resin has good elongation and impact resistance while maintaining high bonding strength. It can better adapt to the requirements of stone in different use environments and improve the reliability and durability of stone products.
(3) Improvement of wear resistance
In some places with high wear, such as floors and stairs, the wear problem of stone surface is more prominent, affecting the service life and aesthetics of stone. In order to improve the wear resistance of stone, researchers added lubricants such as polytetrafluoroethylene micropowder and graphite to epoxy resin, and enhanced the wear resistance of epoxy resin through cross-linking modification technology.
These modification measures reduce the friction coefficient of epoxy resin coating and significantly improve wear resistance. It can effectively resist external wear, keep the surface of stone smooth and intact, and extend the service life of stone.
Comprehensive application cases of epoxy resin in improving the performance of stone products
(1) Production of high-end stone crafts
In the production of high-end stone crafts, the quality and appearance of stone are extremely high. Veropoxy has successfully improved the performance and quality of stone crafts by cleverly using epoxy resin. In the process of making handicrafts, epoxy resin is first used to repair and reinforce the stone to ensure the integrity and strength of the stone.
Then, the modified epoxy resin is used as a surface coating to provide all-round protection for the stone, while enhancing its gloss and color vividness. After such treatment, the stone handicrafts are not only exquisite in appearance, but also have high durability and stability, which can meet the needs of the high-end market and enhance the added value of the product.
(2) Application of large-scale stone building decoration
In large-scale stone building decoration projects, the installation and use of stone face many challenges, such as the heavy weight of stone, high installation difficulty, and complex use environment. Epoxy resin plays a key role in these projects. In the process of stone installation, epoxy resin is used as a binder to ensure the firm bonding of stone and the base layer and prevent the stone from falling off and shifting.
At the same time, epoxy resin adhesive and protective coating are applied on the back and surface of the stone respectively, which enhances the strength and weather resistance of the stone and enables it to better adapt to the test of the outdoor environment. Through this comprehensive application, not only the safety and durability of stone building decoration are improved, but also the overall beauty and quality of the building are improved.
