A spray-on mineral-fibre insulation material. Using Dendamix Marine as noise or thermal insulation is said to give substantial savings to shipyards, since the adhesive used to spray the fibre directly onto shotblasted and primed steel gives a permanent bond. It precludes any necessity for advanced paint coatings. For A60 steel bulkheads, the material is applied at 45mm thickness over plate and 18mm over stiffeners, at a density of 112kg/m3 .
