Anti Rust Product Comparison – CRC Soft Seal Heavy Film & CRC SP 400 | PT Panca Makmur Baru
In various industrial and automotive corrosion protection needs, especially for long-term storage and extreme conditions, the right corrosion inhibitor is essential to protect metal components from rust and degradation.
Two popular CRC products that are widely used are CRC Soft Seal Heavy Film and CRC SP-400 Corrosion Inhibitor. Both provide anti-corrosion protection, but they have slightly different characteristics to suit your industrial application needs.
CRC Soft Seal Heavy Film
CRC Soft Seal Heavy Film is a transparent, flexible, dry wax-coated anti-corrosion aerosol. The resulting film provides long-term protection for metal surfaces, resisting cracking or peeling even when exposed to moisture, salt vapor, or corrosive environments. CRC Soft Seal is suitable for long-term storage components, machine assemblies, and sensitive metal parts that must remain corrosion-free.
CRC Soft Seal Advantages:
- Protects surfaces for up to ±2 years under severe conditions
- The transparent coating does not damage plastic, rubber or paint.
- Ideal for metal, electrical terminals, machinery, molds and industrial components
- The wax structure is not easily peeled or brittle
- Easy to apply and can be removed with CRC Brakleen or other solvents
CRC SP-400
CRC SP-400 is a waxy film corrosion inhibitor designed for metal protection under both indoor and outdoor conditions, including during long-term transportation or storage. The resulting film provides protection against moisture, rain, and corrosive elements such as salt vapor, making it particularly effective on heavy metals and large industrial components.
CRC SP-400 Advantages:
- Long-term corrosion protection (up to ±2 years)
- The wax film is moisture-proof and resistant to outdoor conditions.
- Can be applied to large metal surfaces, steel structures, shafts, motors, and machine tools.
- Easy to apply to large areas with an aerosol spray or bulk pail
Key Differences: Soft Seal vs SP-400
| Aspect | CRC Soft Seal Heavy Film | CRC SP-400 Corrosion Inhibitor |
| Film Type | Transparent, flexible waxy film | Waxy, dense, moisture-proof film |
| Ideal Application | Small/medium components, electrical, machinery | Large components, outdoor structures |
| Duration of Protection | Up to 2 years | Up to ±2 years (depending on application) |
| Main Uses | Indoor & storage components | Indoor & outdoor, transportation |
| Suitable for | Instruments, molds and fine metals | Steel structures, shafts, large machines |
In other words, both products provide high levels of corrosion protection, but Soft Seal is more flexible in sensitive and delicate parts, while SP-400 is stronger in large and outdoor structures.
Why is Anti-Rust CRC Important in Industry?
The use of corrosion inhibitors such as CRC Soft Seal and SP-400 is very important because:
- Protects machinery and material investments from corrosion degradation
- Reduce maintenance downtime
- Maintaining the performance of components stored for a long time
- Increase the service life of industrial equipment
Both CRC Soft Seal Heavy Film and CRC SP-400 provide long term anti corrosion protection for metal, but the best choice depends on the component size, environmental conditions, and specific applications in your industry.
