What we offer

Portfolio at a Glance

Danutec’s SE (Semi-Preg) portfolio delivers low-void composites using in-process resin film infusion technology, merging the full performance of solid prepreg with resin infusion benefits.

Hotmelt epoxy matrices ensure high mechanical strength by eliminating interlaminar air entrapment and enabling in-situ fiber wetting. VOC-free, odorless resin chemistry outperforms liquid infusion, RTM, and wet-layup methods.

Compatible with Glass, Carbon, Flax, Aramid, and more, available as wovens and non-crimp fabrics. Fiber areal weights range from 48 to 2000gsm, making SE solutions ideal for surface applications and multi-layer composites requiring precision, safety, and superior performance.
