Description
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, Arjays 5121 Brushable Radius Compound has excellent crack resistance, reduces finish work and helps provide better overall cosmetics.
5121 Premium Performance Benefits

Avoiding print is possible with Arjay’s 2121 & 5121 products
In recent years boat builders increasingly have designed sharp radii and style lines into their models. The challenge on the floor becomes laminating those tight radii and not leaving air voids. Plus, this has to be done without creating other problems like gel coat cracks and print caused by heat and excessive resin shrinkage. Arjays Radius Compounds rise to these challenges by providing a tough, resilient, low shrink substrate between the gel coat and skin laminate that will allow you to produce void free parts that require little to no finish work.
2121 Performance Benefits
- Lower exotherm and shrinkage for better finishes
- Reduces air voids and dry fibers in laminates
- Eliminates surface cracks and blemishes
- Maintains resiliency to resist cracks
- High impact resistence
