Chryso SA has introduced a new biodegradable, vegetable-based de-moulding oil – Chryso Dem Aqua 100 – which can be used with all types of formwork, including formwork not usually suited to mineral-based mould release agents.
Unlike many de-moulding oils that are toxic and non-biodegradable and pollute the soil and groundwater when the formwork is washed or rainwater runs down it, Chryso Dem Aqua 100 will not contaminate the environment. Tests from a certified laboratory have shown that Chryso Dem Aqua 100 has an ultimate biodegradability above 60% at 28 days.
The new de-moulding agent has the further benefits that it creates a consistent, smooth and blemish-free concrete surface with reduced blow holes; less dusting of mould surfaces is required; and it does not leave stains on the concrete.
It offers an ideal solution for concrete manufacturers with stringent surface quality requirements and is particularly suited to the production of architectural and decorative products. It produces regular and repeatable results in variable working conditions.
When Chryso Dem Aqua 100 is sprayed onto mould surfaces it forms a homogenous film of fine droplets on the formwork, providing an immediate visual aid to ensure complete and uniform application and preventing over-application. The product is economical and can be used at a coverage rate of below one litre per 50m2 of treated surface area.
Chryso Dem Aqua 100 is one of a growing number of ‘green’ products developed by the company for the construction industry over the past few years.
