Thermosets offers many opportunities for innovative composite manufacturing. Knowledge about the material science of thermosets is crucial as there are some challenges in producing 3D-printed parts at high rate and high quality. Learn more!
In the last few years, the nail polish industry has really opened up its beauty box of tricks and on the market today. Surely there must be some exciting science behind it all? Learn about curing and the influence of pigment – all measured with a Kinexus Rotational Rheometer!
Erst in den letzten Jahren hat die Nagellackindustrie ihre Schönheits-Trickkiste so richtig geöffnet und auf den Markt gebracht. Doch warum „stempelt“ Stempel-Nagellack, „zieht sich“ Crackling-Lack „zusammen“ und „härtet“ UV-Nagellack „aus“? Lernen Sie mehr über Aushärtung und den Einfluss von Pigmenten – gemessen mit einem Kinexus Rotationsrheometer!
During the Vat Photopolymerization process, the component is built-up in layers in a liquid resin vat using a UV laser beam to selectively cure the resin. Learn how the degree of thermal cross-linking of a two-component resin is determined by the preceding cross-linking reaction during photo-polymerization.
Popular materials for lightweight applications are glass and carbon fiber-reinforced plastics. The properties of the composite material are determined by the manufacturing process conditions. Therefore, it is crucial to know the curing state reached during manufacturing as well as the correlation between the glass transition temperature and degree of cure.

BLACKS Composites SRL and NETZSCH Analyzing & Testing made the next milestone in its already proven Partnership: Improving the curing of a CFRP bike rim with a simultaneous drastic reduction of the cycle time during cross-linkage. The bike rim was processed through hand lay-up technology and a subsequent autoclave curing. Saving cycle time with a better curing is not possible? It is! Based on the data of a differential scanning calorimeter and the simulation software Kinetics Neo, the cycle time was reduced by 46% compared to the cure cycle suggested by the material data sheet. Additionally, a higher degree of cure could be achieved to meet the target curing and avoiding overheating effects of the product.
