Overview
JS-ER13-2400-180 is a 180 assembled roving for spray-up, coated with a silane-based sizing that is compatible with unsaturated polyester, vinyl ester, and polyurethane resins. As one of the recommended international brand products in our glass fiber range, this roving is supplied with supply chain resource support for composite manufacturers sourcing spray-up reinforcement. Assembled roving is a common reinforcement format for spray-up work because it feeds consistently through a chopper gun, giving operators a steady, repeatable process compared with less uniform reinforcement formats.
Key Features of JS-ER13-2400-180
- Excellent static control
- Excellent choppability and dispersion
- Fast and complete wet-out, ensuring easy roll-out and rapid air release
- Excellent strength of the composite products
- Excellent hydrolysis resistance of finished parts
Resin Compatibility
The silane-based sizing on this roving is compatible with unsaturated polyester, vinyl ester, and polyurethane resins, giving fabricators flexibility to pair it with the resin system already specified for their process, rather than requiring a separate reinforcement grade for each resin chemistry. Sizing compatibility matters because a mismatch between fiber sizing and resin chemistry can lead to poor fiber-to-resin bonding, which shows up as reduced mechanical strength or premature delamination in the finished part, even when the resin and reinforcement are each individually within specification.
Applications
This roving is a versatile general-purpose spray-up product used to manufacture:
- Boats and yachts
- Sanitaryware
- Swimming pools
- Automotive parts
- Pipe, by centrifugal casting process
These applications span our Marine Vessels and Automotive & Transportation industry categories, where spray-up processing is widely used for medium-to-large composite parts with moderate structural requirements.
Why These Properties Matter in Spray-Up Processing
In spray-up processing, roving is fed through a chopper gun that cuts it into short strands and combines it with catalyzed resin as it is sprayed onto the mold surface. Good static control reduces fiber clumping and fly-away strands during chopping, which supports more even fiber distribution across the mold. Excellent choppability and dispersion help the chopped strands spread out rather than bunching together, reducing the risk of resin-rich or fiber-rich patches in the finished laminate. Fast, complete wet-out matters because operators need to roll out air pockets before the resin begins to gel; a roving that wets out quickly gives the crew a more workable window to consolidate the laminate. Hydrolysis resistance in the finished part is particularly relevant for swimming pools, boat hulls, and other applications where the composite is in prolonged contact with water. Excellent strength of the composite products also depends on consistent fiber distribution and complete wet-out, since dry spots or resin-rich pockets are typically the weak points where a laminate first fails under load.
