In the world of road signs, not everything is white or yellow. What really makes the difference is in the resin that you can’t see 👀
Today we want to share a clear comparison between two protagonists in thermoplastic painting: alkyd resin vs hydrocarbon resin.
🔬 Alkyd resin
We are talking about a more advanced formulation, based on modified polyesters. The result?
- Greater adhesion to the pavement
- Excellent flexibility (fewer cracks with thermal changes)
- Better resistance to aging (UV, oxidation)
👉 It is the ideal choice when long-term durability and performance are the goal.
🛢️ Hydrocarbon resin
Derived from petroleum (C5), it is the most widespread option in many projects.
- Lower cost
- High initial hardness
- Fast and efficient application
👉 Perfect when cost optimization and agile ex*****on prevail.
⚖️ The key is not which one is better, but which one is right
Choosing between one or the other depends on factors such as:
✔️ Traffic intensity
✔️ Weather conditions
✔️ Frequency of maintenance
✔️ Project Budget
💡 In demanding projects or with large thermal variations, investing in an alkyd resin often results in less long-term maintenance.
💡 In more standard actions, hydrocarbons continue to be an effective and competitive solution.
In the end, a good technical decision today. It is noticeable on the road for years.
