Garnet sand type WIWOX® WÜ belongs to the group of garnet stones. The grains are unbroken with irregular shapes. Its unique composition makes the garnet sand tough and hard and particularly suitable for blasting applications in the open. With its the low quartz content (< 0,5 %), it complies with occupational health and safety regulations. Its countries of origin are India and Australia.

WIWOX® EDK Stainless steel blasting abrasives are produced in a melting process and crushed into angular granules. It is distinguished by its long service life as well as its aggressiveness and presents an economic alternative to other angular blasting abrasives.

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.
