1. Composite Surface Technology & Coating Updates
1.1 Hexcel HexPly XF Surface Technology Evolves
Hexcel continues to evolve its HexPly XF surfacing technology — a surface solution designed for large infused or prepreg composite components, delivering high-quality, pinhole-free, paint-ready surfaces straight from the mold, significantly reducing post-mold sanding and painting steps.
- Key advantages: Pinhole-free surface straight from demold, no additional putty or sanding required
- Applications: Large composite parts, wind turbine blades, automotive exterior components
- Industry significance: Surface technology is a key enabler for the "demold = finished product" trend in composite parts

1.2 SHD Composites Develops Prepreg for Automotive Cosmetic Parts
SHD Composites, in collaboration with AGN, developed the MTC510-1 advanced prepreg system specifically for Dissident Automotive's carbon fiber Porsche cosmetic components.
- Product features: Hot-melt prepreg designed specifically for visually demanding carbon fiber components
- Process advantages: Handling characteristics comparable to solvent-based prepregs; familiar processing behavior while achieving required surface appearance
- Surface requirements: Cosmetic parts require extremely high surface quality: clear weave, pinhole-free, consistent gloss
BASTAIN, a brand under JHINNOV, offers high-performance in-mold gel coats matched to hot-melt prepreg systems, delivering pinhole-free demold with clear weave visibility — ready for direct clear coat application, eliminating multiple manual sanding steps for composites manufacturers.
