Concrete Demoulding Agent
DM 40 is a kind of efficient water-soluble environmental friendly demoulding agent for the mould of concrete casting. It gives excellent mould release performance by uniform film forming on the surface of the mould, which effectively extends the service life of the mould plate. With DM 40, hardened concrete after demoulded shows perfectly smooth and glossy surface and appearance.
DM 40 can be used for demoulding of concrete products such as tunnel segment, bridge, GRC, large-scale prefabricated component, etc, and for moulds made of different materials such as steel mould, wood mould, plastic mould, aluminum alloy, etc.
Application method
- Clean the mould plate for the first time use. If the mould plate is clean, the effect of DM 40 could be influenced
- Dilute DM 40 with water in proportion of 1:3~1:8, exact dilution ratio needs to be determined by test depending on the mould condition and application process
- DM 40 is applied by brushing, rolling or spraying to the surface of mould plate. Spraying process is highly recommended
- After DM 40 applied, wait for 15~50min (at 25℃) to dry until milk-white becomes transparent. If the mould is uneven, use gauze or brush to evenly coat the oil film
- If some area DM 40 accumulates, spread to even by brush or gauze
- After concrete casting and harden, remove the mould from the least dilution ratio area for the first time use, gradually adjust to the optimum dilution ratio to achieve the best demoulding effect.
