Application
GLYDOL 1161 is used for cleaning pressure casting resin moulds. Depending on the form, the material in use and the porosity of the mould, fine particles collect in the capillaries after a time and clog them, whereby the suction force of the mould is reduced.
The mode of action of GLYDOL 1161 depends on the fact that its wetting properties loosen deposits, and its complexing properties allow it to rinse out multivalent cations, e.g. calcium, magnesium or aluminium.
GLYDOL 1161 can either be used for cleaning the mould pores and capillaries, or for cleaning the mould surface. For cleaning the mould pores, a 2.5 – 5.0% solution is produced by mixing GLYDOL 1161 with water. This solution can be introduced into the mould channels or capillaries by water pressure or vacuum. For cleaning the mould surface, GLYDOL 1161 can be applied to the mould undiluted or diluted with water in the ratio 1:1.
After a certain contact time, which depends in both cases on the degree of soiling or clogging, the mould should be rinsed through several times with water followed by air. During its contact time, the mould must be kept humid. For this purpose it should be closed.
A modification of the product reduces possible foaming tendency to a minimum.
In order to prevent too rapid ageing of the moulds, we recommend cleaning them before work breaks, before a machine stop, and at least 1 – 2 times during each working shift.
After the mould has been used, it can be stored in water. The addition of 2 – 4% GLYDOL 1161 dissolves further calcium deposits and prevents clogging of the capillaries. In case of longer storage in water, about 0.2% of a preservative such as, for example, our PREVENTOL®-types should be added to the water.

General notes regarding mould cleaning
- In order to prevent rapid ageing of the mould, it should be cleaned with GLYDOL 1161 even from the very beginning.
- The mould channels should be arranged in such way that the cleaning solution can reach sections which are difficult to access.
- You should take care that also the spaces between the mould and the metal pieces will be cleaned.
- The water hardness of the cleaning water used is very important. Even a water hardness of > 5 °dH can lead to calcium deposits in the pores. Water treatment can prevent this.
- The mould should always be kept humid, during use and also during storage.
