WIWOX® 410 is a liquid, alkaline mould cleaning agent for the removal of burnt rubber and plastic residues from metallic surfaces. It is also used as a paint stripper. WIWOX® 410 is used undiluted for immersion cleaning of metal moulds. The construction material for the tank can be sheet steel or stainless steel. The tank size depends on the moulds to be cleaned. The pool can be heated from the outside or inside by a heating coil. The processing temperature is generally approx. 80° C. The processing time depends on the degree of soiling and the type of soiling between 10 – 30 minutes.

WIWOX® 340 is a weakly alkaline cleaning agent for grease, oil and oil carbon soiling. Very suitable for pre-cleaning or basic cleaning of soiled steel, cast iron and non-ferrous metal or plastic parts in an ultrasonic bath or in a spray cleaning system. After cleaning and without water rinsing, the parts are temporarily protected against corrosion. The final drying can be accelerated by blowing off with compressed air, a warm air flow or treatment in a drying cabinet. WIWOX® 340 can be used in a concentration of 5 – 7 %. Dilution with water depends on the degree of contamination and the intended exposure time. The bath should have a temperature of approx. 60° C. The bath should be kept at a constant temperature. In the field of precision mechanics, longer exposure times are possible depending on the degree of contamination.

WIWOX® 250 is a very alkaline cleaning concentrate for organic (oil, coal, grease etc.) and inorganic (magnesium, lime etc.) residues on tools and moulds. It can be rinsed off residue-free without a film on the surface. The concentration depends on the working conditions, the degreasing time, the degree of soiling, etc. (between 5 – 30 %). Regular replenishment by checking the bath can prolong its service life. In contrast to powder concentrates, lthe iquid formulation allows convenient use without danger of exothermic reaction in the plant.

Plastic is a thermoplastic and belongs to the organic polyamidebased blasting abrasives. WIWOX® KS nature high-quality blasting and deburring medium is particularly suitable to treat duroplast and rubber components without damaging and matting them. Available in cylindrical or exact cubic shape, it is characterised by high impact strength, dimensional stability and extremely long service life. We also supply an antistatic agent for subsequent or sustained application in liquid form.
