FR Hook & Loop Fasteners, Adhesive-backed
SKU# FRABH100
These hook and loop fasteners have a PSA backing (Pressure-Sensitive Adhesive), and are ideal for light-to-medium duty applications, such as adhering lighter weight panels or holding down seat cushions in automobiles, boats, trains, and airplanes. The adhesive performs well in direct sunlight and high temperatures on a wide variety of surfaces, such as glass, metal, painted metal, and rigid plastics. Avoid with plywood, EVA, and PVC.

Note: Hook and Loop ("Velcro") failures are common in Vertical Burn testing across all brands. Most fasteners are manufactured from nylon or similar synthetic materials that are inherently flammable. These materials typically pass the standalone 12-second Vertical Burn test because they liquefy and drip during combustion; this process carries the flame away from the sample, allowing it to self-extinguish.
However, when the same fastener is attached to a substrate like leather, it is prevented from dripping. This causes the flame to linger and intensify on the material, leading to a failure. In our experience, this occurs in approximately 20% of cases. Leather is particularly problematic as it tends to shrink and contract, further concentrating the flame.
For projects involving Oil Burn Testing a simple solution may be for your laboratory to test the Hook and Loop independently, provided the Oil Burn test also passes.
For all other testing categories, there are unfortunately no ideal solutions. The available options include:
- Applying a flame retardant: This is generally ineffective as the treatment cannot sufficiently penetrate the nylon fibers.
- Sewing instead of gluing: While this may slightly improve performance, the fundamental combustion issue remains.
- Switching brands: This rarely resolves the issue, especially when testing on leather, as the substrate itself is often a primary contributor to the failure.
- Utilizing "Radiant Panel" rated fasteners: Specialized fasteners are designed for these conditions. This is the only method to guarantee a passing result, though it does involve a significantly higher cost.
