Understanding the Key Differences
When selecting a line marking material, understanding the differences between Cold Applied Plastic (CAP) and traditional thermoplastic is essential. Both are durable options with distinct advantages and disadvantages depending on your application.
What is Thermoplastic?
Thermoplastic is a heat-applied line marking material that has been used in road and car park marking for decades. It requires specialized heating equipment to reach temperatures of 180-220°C before application, creating a strong bond with the surface. Once cooled, it forms a hard, durable marking.
What is Cold Applied Plastic (CAP)?
Cold Applied Plastic is a two-component material that uses a chemical reaction (MMA-based) to cure and harden at ambient temperature. No heating equipment is required, making the application process simpler and safer.
Comparison Table: Durability
| Metric | CAP | Thermoplastic |
|---|---|---|
| Expected Lifespan | 5-7 years | 3-5 years |
| Initial Cost | Higher | Lower |
| Long-term Value | Better | Good |
Application Temperature Considerations
Thermoplastic: Requires heating to 180-220°C, which can pose safety risks and require specialized equipment and training.
CAP: Applied at ambient temperature, making it safer and more accessible for various conditions and seasons.
Weather Performance
Both materials perform well in Australian weather conditions. Thermoplastic can become softer in extreme heat, while CAP maintains consistent performance across temperature ranges. Both offer excellent UV resistance and water repellency.
Reflectivity and Safety
Both CAP and thermoplastic can be formulated with high-visibility properties and reflective elements. The reflectivity levels are comparable, with both meeting AS standards for road safety.
Cost Analysis Over Time
While CAP has a higher upfront cost, the extended lifespan (5-7 years vs 3-5 years) means fewer re-applications over a 10-year period. For high-traffic areas, CAP typically offers better value over the long term.
Which Should You Choose?
Choose Thermoplastic if:
- Budget is the primary concern
- You need quick installation
- Markings will be re-done within 3-5 years
Choose CAP if:
- You want long-term value and durability
- You're in a high-traffic area
- You prefer safer application methods
- You want to minimize maintenance frequency
Expert Recommendation
For most commercial applications in Sydney, especially high-traffic car parks and roads, Cold Applied Plastic offers superior value when considering the total cost of ownership. However, the best choice depends on your specific needs, budget, and long-term plans for the property.
