Heavy-Duty Anti Corrosion Silicone Resin | SIOResin® SIO-516
SiO-516 is a high-performance, two-component, room-temperature curing Heavy-Duty Anti Corrosion Silicone Resin system. It cures quickly at room temperature and provides outstanding aging resistance, excellent high and low-temperature resistance, and strong anti-staining properties. The coating is easy to clean, highly durable, wear-resistant, and retains both color and gloss over time. Designed for heavy-duty anti-corrosion systems, SiO-516 offers exceptional chemical and UV resistance, making it ideal for environments requiring long-lasting protection.
This innovative resin simplifies traditional three-layer heavy-duty anti-corrosion systems into a two-layer system: an epoxy primer (or epoxy zinc-rich primer) paired with the heavy-duty anti-stain silicone resin topcoat. It is suitable for use in C5 and higher corrosion-resistant environments. SiO-516 is packaged as A and B components for easy application. Unlike fluorocarbon paints, which release toxic gases like phosgene and fluorolefin during combustion, SiO-516 is fluorine-free and does not produce harmful gases under high temperatures, making it a safer and more environmentally friendly alternative.

Typical Physical Data
Curing Conditions
Recommended room temperature curing: surface dry within 2 hours at 25°C, optimal performance after 7 days. To speed up curing, low-temperature baking is recommended: 80-100°C for 15-30 minutes, with optimal performance achieved after 7 days. Refer to application experiments for specific conditions.
Usage Instructions
1. Paint Preparation: Add pigments, fillers, leveling agents, wetting agents, defoamers, and other additives to component A and mix thoroughly before combining with component B. Use a diluent (recommended ETB) to thin the resin as needed. The amount of diluent should be determined based on actual requirements.
2. Application Method: Apply by spraying. Clean the substrate thoroughly, remove oil and rust, and increase substrate roughness to improve adhesion. Control the coating thickness to 30-50μm. Use the mixed product within 0.5 hours or use a two-component spray gun.
3. Curing Conditions:
* Natural drying at room temperature: surface dry in 2 hours, 4H hardness in 7 days.
* Low-temperature baking: 80-100°C for 15-30 minutes to accelerate surface drying.
* Achieve maximum hardness and optimal performance after 7 days.
* Choose the appropriate drying temperature based on solvent evaporation rate. For solvents with high boiling points and slow evaporation rates, bake at 80-100°C to speed up solvent evaporation. Residual solvent will significantly affect the hardness and adhesion of the coating.
4. Coating System: As an excellent topcoat, silicone resin anti-corrosion coatings can be paired with primers and intermediate coatings to form a classic heavy-duty anti-corrosion system. Common schemes include:
* Steel Structure System: Epoxy zinc-rich primer (80μm one layer) + silicone resin topcoat (70μm one layer).
* Bridge System: Epoxy zinc-rich primer (80μm one layer) + silicone resin topcoat (100μm one layer).
* Outdoor Building System: Epoxy sealer primer (25μm one layer) + silicone resin topcoat (40μm one layer).
Precautions
- After pouring out the resin, wipe the excess from the container opening, tighten the cap, and store in a cool place.
- Clean brushes, spray guns, and other equipment with diluent immediately after use.
- Strictly avoid open flames and ensure good ventilation during application.
- The product has a slight odor and may cause mild irritation to skin and eyes. In case of contact, rinse immediately with plenty of water and seek medical attention if necessary.
- Exercise caution when applying at ambient temperatures below 15°C or relative humidity above 75%.
- Store in 200KG drums in a cool, dry place away from light. The storage temperature should be 5-25°C, and the packaging should remain intact. The shelf life of both the main agent and the curing agent is 12 months. Protect the curing agent from moisture, and use it up once opened.
