For filling hollow spaces or shapes such as boats, relief forms, figures or models. You can imitate wood with H 75 if you cast it in a silicone mould. Due to the closed cell structure, suitable for long-term contact with water, can be painted, glued, filled, nailed and screwed. Can be coloured with 5% PUR pigment. Attention: does not give a homogenous colour. When exposed to sunlight, the material may discolour after a while.


Mix individual components thoroughly. Mix both components in a 100/145 ratio by weight and pour the mixture into the shape or area to be filled. The potlife is approx. 60 sec. The expansion is approx. 13 x the volume. Dry after 15 min. De-formable after 20 min. and fully cured after 12 hours. Make sure the processing temperature is between 20°C and 25°C. Store the foam between 10°C and 25°C because of frost sensitivity. Mixing is best done with a mechanical mixer. As a release agent we recommend APW.
Always provide appropriate protective clothing and gloves. Avoid prolonged skin contact. The use of a carbon filter mask type A2 is recommended. Caution: container may be under pressure. Cleaning agent for tools: cleaner M (environmentally friendly substitute for acetone).
