A Viscosity that Works
We provide different viscosities for the different ways you use Arjay Radius Compound. 5121 provides a brush-in solution for larger components and the industry’s go-to solution to prevent air voids
A Brushable Radius Made with
Premium Vinyl Ester Resins
Higher viscosity and physical strength, with the same time-saving blister and impact resistance
Arjay formulates its 5121 Brushable Radius Compound with premium vinyl ester resins, resulting in high physical strength, excellent blister resistance and HDT > 200 °F. It is formulated especially for filling behind the gel coat of tight radii and bonding glass to glass joints. In addition, Arjay’s 5121 Brushable Radius Compound has excellent crack resistance, reduces finish work and helps provide better overall cosmetics.
5121 Premium Performance Benefits
- Formulated with premium vinyl ester resins
- Very low volume shrink, reduces air voids
- Low styrene content
- Maintains resiliency to resist cracks
- Excellent durability and impact resistance
What Makes 5121 Premium?
We took our 2121 and added premium resin--and more of it--to create a brushable radius compound that is even stronger and more crack resistant. If your application requires strength, higher flexibility, and class A cosmetics, pick 5121.
