Fibermaq has developed three accessories for spray-up and gelcoat machines – own and other brands.
The first is a filter installed between the outlet of the peroxide (MEKP) packaging and the pump that pushes the material up to the gun. “Any impurities in the MEKP may cause problems in the sealing and, as a result, a peroxide failure,” explains Christian de Andrade, Director of Fibermaq.
Also in relation to MEKP, the company launched a flowmeter for the composites moulders. The accessory allows the moulder check whether or not the peroxide is mixed with resin and gelcoat. “The flowmeter shows if the MEKP is being pumped and alerts the operator to a problem in the system, allowing the actions to be taken in time.”
Finally, Fibermaq changed the filtering system of the tube connected to the resin and gelcoat packaging. With threaded fitting, rather than screw, and smaller mesh than the previously used, the filter is much more efficient.
Solvay has celebrated the groundbreaking of its Greenville, Texas, US, manufacturing footprint expansion that increases the site’s resin mixing capacity to meet the growing needs of commercial and military aerospace composite customers.
Aimplas is participating in the European project Mat4Rail: Designing the Railway of the Future: Fire Resistant Composite Materials and Smart Modular Design.
One of the most challenging applications for methyl ethyl ketone peroxides (MEKP) occurs in gelcoats, reports Brazilian company Polinox. Hybrids of resins and pigments that protect and finish composite parts, gelcoats undergo important changes in their performance if the peroxide exhibits, for example, a high concentration of water. The company says defects such as roughness and early yellowing of the laminate can be avoided with the adoption of peroxides such as its Brasnox DM50.
