Henkel will exhibit its Frekote products at JEC Europe, Porte de Versaille in Paris, France, next week.
Henkel describes the products as highly efficient solutions for complex mould geometries which will be displayed in addition to adhesives and sealants. The mould release agent, Loctite Frekote is applied to the mould, where it results in an extremely thin, heat-resistant layer that combines chemically with the surface of the mould, thereby sealing even micro-porosity.
According to Henkel, the Frekote line is the industry’s largest range of semi-permanent release agents, sealers and cleaners.
The range includes the latest innovations: Loctite Frekote CS-122, RS-100 and C-400. CS-122 is a pre-treatment product that Henkel says seals porosity exceptionally well. It forms a high-gloss coating within two hours and has minimal odour. RS-100 is a heat-cured sealer for rubber applications. This new pre-treatment product can be applied to the mould at temperatures of up to 200°C and then cures in just five minutes. RS-100 is water-based and non-flammable. C-400 is a water-based release agent that is particularly suitable for producing high-gloss coatings on polyester parts, e.g. for visually attractive vehicle spoilers, truck cabs and yacht bodies.
Henkel explains that the transition from fossil fuels to renewable energy sources is posing major challenges for the manufacturers of wind energy plants. Improving the availability of the plants themselves and the productivity of existing production facilities are key factors in ensuring economic viability. Rapid manufacturing processes are required to ensure that capital investments pay off. Traditionally, blade shells and spars have been bonded using two-component epoxy resins. While these materials reliably meet the extremely high mechanical specifications, they delay the automated manufacturing process.
Alternative adhesives such as Macroplast UK 1340 from Henkel are therefore designed to speed up production. Here Henkel explains it has succeeded in developing a PUR adhesive that makes rotor blade production more efficient and satisfies the specific mechanical requirements for use in the wind power industry. Polyurethane-based adhesives react quickly, which means that Macroplast UK 1340 cures much faster than the epoxy resins used up to now. This, it says, minimises not only the duration of the cure phase, but als+o the release of energy and thus the temperature during curing.
Henkel can be found at booth R45.
