Water based release agent 1801/38 – shiny
The demand of water based products has significantly increased over the last years for ecological and safety reasons.
Therefore the company Keck has decided to invest a big part of its R&D in the development of water based products. Those products are so performant as the solvent based one. It is important to follow our technical instructions in order to achieve satisfactory results.
Our laboratory has recently developed the water based release agent 1801/38 for polyeter polyurethane unit soles or polyeter soles directly injected onto uppers.
The product 1801/38 gives a shiny outlook to the soles, once the polyurethane is injected.
We recommend to use a spray gun with a 0.3 mm nozzle and to use following pressures : air pressure : 3 to 4 bars, material pressure : 0.8 bar.
The temperature of the mould should be around 50°C in order to get the best results.
It is important to keep a certain distance, 20 to 30 cm, between the spray gun and the mould in order to obtain a uniform release agent film inside the mould.
The product 1801/38 is drying quite fast. However it is important to wait minimum 2 minutes before injecting the polyurethane. Another option can be to use a airsrpay gun and the drying time can be faster.
1801/38, contrary to other existing products, causes less build up inside the mould. The outlook of the final product is shiny and the surface uniform.
We recommend to store this product in a room at stable temperature not under 10 °C and not above 45°C.
