Key Differences Between Raka and WEST SYSTEM Epoxy
When it comes to selecting the right epoxy system for your project, it’s important to consider all the details. So, let’s delve deeper into the key differences between Raka and WEST SYSTEM epoxy.
For a newcomer to the world of epoxy, the simplicity of the Raka epoxy system is a major advantage.
The straightforward mixing ratios offered by Raka – typically 2:1 or 5:1, depending on the specific product – are less confusing for beginners.
The long pot life also allows for a more relaxed pace of work.

- Versatility and Customizability
The extensive product line of WEST SYSTEM epoxy is a big win for those seeking flexibility and customization. You can choose from different hardeners and additives to meet the specific needs of your project, be it faster cure times, increased flexibility, or improved resistance to environmental factors.
Raka, on the other hand, doesn’t provide as extensive a range of customization options. But, it does offer a few hardener options that cater to different temperature and cure time requirements.
From a cost perspective, Raka epoxy is typically more affordable than WEST SYSTEM epoxy. This cost-effectiveness makes Raka an attractive option for hobbyists and professionals who have budget constraints.
WEST SYSTEM epoxy, while a bit more expensive, offers value for money considering its versatility and the high-quality finish it delivers.

- Aesthetic Considerations
When it comes to aesthetics, Raka epoxy scores for its clear finish which is ideal for transparent coatings and laminations. However, it can develop a slight yellowish tint over time.
On the other hand, WEST SYSTEM epoxy maintains its clarity and color stability over time, a critical factor for projects where the visual appeal of the finished product is paramount.
