Product Description
Deep Penetration Epoxy for Granite Repair – DF270-10 / BCO25Q is a two-component epoxy resin system specially developed for repairing micro-cracks and internal fissures in granite. Its ultra-low viscosity allows the resin to penetrate deeply into dense stone structures, ensuring reliable internal reinforcement rather than surface-only repair. This precisely engineered viscosity range is what sets this product apart from conventional epoxy systems. At this optimal viscosity, the resin flows readily into microscopic cracks and pores that would remain unfilled by higher viscosity products, yet maintains sufficient body to stay in place during application. The result is complete internal reinforcement that strengthens the granite from within while leaving no visible surface. Unlike standard epoxies that merely coat the surface, our Deep Penetration Epoxy for Granite Repair becomes an integral part of the stone structure, providing long-lasting structural integrity.

Product System Description
This product is a two-component epoxy resin system:
Component A: DF270-10
Component B: BCO25Q
The system is carefully engineered to achieve optimal penetration and reinforcement when mixed according to the specified 100:25 ratio under recommended processing conditions at 24°C. The ultra-low viscosity is the result of extensive formulation development to provide the ideal balance between flowability for deep penetration and film-building properties for effective wetting. This precise control ensures that the resin flows readily into micro-cracks and pores as narrow as a few microns, while maintaining sufficient body to stay in place during application. The DF270-10 resin component is specifically formulated for low viscosity characteristics, while the BCO25Q hardener is designed to maintain these flow properties during the extended working time. Together, they create a system that can penetrate deeply into dense granite structures that would resist conventional epoxy systems. Mixing ratio, pot life, and curing conditions are available upon request for specific application requirements.
Unlike standard epoxy systems that may have higher viscosities, our DF270-10 / BCO25Q system maintains consistently low viscosity throughout its working life. This lower viscosity is critical for black granite applications, where the dense crystalline structure creates microscopic pathways that only low viscosity resins can navigate. The formulation has been proven through extensive testing to provide optimal penetration without sacrificing the mechanical properties needed for durable reinforcement.
Processing Suggestions
- Clean cracks thoroughly and remove all dust before applying this Deep Penetration Epoxy for Granite Repair. The low viscosity will flow best into clean, debris-free cracks.
- Mix components thoroughly according to the specified 100:25 ratio to achieve optimal viscosity and ensure proper curing.
- Apply epoxy by brushing, dripping, or injection methods to ensure complete coverage. The formulation will naturally flow into cracks and pores without forcing.
- Allow sufficient time for deep penetration – the low viscosity continues to flow for an extended period, so patience during this phase ensures complete filling.
- Maintain ambient temperature around 24°C for optimal curing results and to preserve the desired flow characteristics. Lower temperatures may increase viscosity and reduce penetration.
- Monitor application to ensure uniform coverage across all treated areas, reapplying if necessary to cracks that absorb the initial application.
- Allow full cure (24-48 hours) before proceeding with polishing or further processing. The extended cure time allows the resin to achieve maximum penetration before hardening.
- Proceed with polishing after full cure is achieved – the deep penetration ensures that repairs remain invisible after surface finishing.
- Clean tools immediately after use before epoxy cures.
Important: Following these processing suggestions ensures optimal performance of your Deep Penetration Epoxy for Granite Repair from professional China suppliers. The low viscosity is key to achieving the deep penetration and strong internal bonding that this system is known for. For best results, always verify that your application conditions are compatible with the formulation.

Frequently Asked Questions (FAQ)
What is this epoxy resin mainly used for?
A: DF270-10 / BCO25Q is designed for deep penetration granite repair, especially suitable for micro-cracks, fissures, and surface consolidation of black granite slabs. Its low viscosity is specifically engineered to penetrate deeply into dense granite structures that conventional epoxies cannot reach, providing true internal reinforcement rather than surface-only repair.
Why is low viscosity important for granite repair?
A: Low viscosity provides the ideal balance between flowability and wetting properties for dense granite. This allows the resin to flow deeply into micro-cracks and pores that may be only a few microns wide, while maintaining sufficient body for effective wetting. Higher viscosity products simply cannot penetrate these fine structures, resulting in surface-only repair that may fail over time.
What is the mixing ratio of this epoxy system?
A: The recommended mixing ratio is 100:25 by weight (Component A : Component B). Proper mixing is essential to achieve optimal viscosity and penetration performance. Always measure carefully and mix thoroughly before application.
How long does it take to cure?
A: The curing time is typically 24–48 hours at a working temperature of around 24°C. This extended cure time is actually beneficial for deep penetration applications, as it allows the resin to continue flowing into cracks throughout the cure cycle. Lower temperatures may extend the curing time, so maintaining recommended temperatures is important.
Is this epoxy suitable for light-colored granite?
A: This product has normal yellowing resistance and is primarily recommended for dark or black granite applications. For light-colored granite where color stability is critical, please contact our technical team for alternative recommendations.
Can this epoxy be used before polishing?
A: Yes, it is commonly used before polishing to reinforce granite slabs, fill micro-cracks, and improve overall slab stability. The deep penetration ensures that cracks are completely filled from within, so after polishing there are no visible repair marks.
How does this epoxy compare to standard granite epoxies?
A: Most conventional epoxy systems have higher viscosities that limit their ability to penetrate dense granite. Our formulation is specifically engineered for deep penetration applications. The lower viscosity allows the resin to flow into microscopic cracks and pores that would remain unfilled by higher viscosity products, achieving true internal reinforcement rather than superficial surface treatment.
What causes micro-cracks in black granite?
A: Micro-cracks in black granite can occur during quarrying, processing, transportation, or due to natural geological stresses. These fine fissures may not be visible to the naked eye but can compromise the structural integrity of slabs over time. Our Deep Penetration Epoxy for Granite Repair is designed specifically to reinforce these vulnerable areas.
Can this epoxy be used in automated production lines?
A: Yes, the system is suitable for both manual application and conventional automatic resin processing lines used in stone factories. The consistent viscosity ensures reproducible results across different batches and application methods.
How should I store this epoxy to maintain its properties?
A: Store both components in a cool, dry place away from direct sunlight at 10°C to 25°C. Proper storage is essential to maintain product specifications. Avoid temperature extremes that could alter the flow properties. Keep containers tightly sealed when not in use.
Are you a factory or trading company?
A: We are a professional manufacturer and factory based in China, specializing in epoxy systems for stone applications. As direct China suppliers, we offer factory direct supply, OEM services, and customized solutions for bulk orders worldwide.
Do you provide samples for testing?
