    • The invention relates to a strip intended for the spray-application of primer on two adjacent surfaces separated by a recessed joint, said strip taking the form of an irregular right triangular prism with an isosceles-triangle-shaped base in which: two sides are equal and the remaining side forms the base, and the two inner angles formed by the base of the triangle with the two equal sides thereof measure between 65° and 75°, i.e. the angle of maximum penetration and maximum compression. The strip is made from expanded flexible polyurethane foam containing polyether with a regular fine-pore structure having a density of between 18 and 22 Kg/m3, enabling same to be produced using a blade cutting machine, and resistance to 40 % compression of between 3.8 and 4.8 kilopascals, thereby providing penetration and side compression force characteristics such that, for the above density, the strip can be held on the recessed joint without adhesives.
    • 本发明涉及一种用于在由凹陷接头分开的两个相邻表面上喷涂底漆的条带,所述带呈等腰三角形基座的不规则的右三角棱镜的形式,其中:两边相等 并且其余侧面形成基部,并且由具有两个相等边的三角形的底部形成的两个内角在65°和75°之间测量,即最大穿透角度和最大压缩角。 带材由具有密度为18至22Kg / m 3的规则细孔结构的聚醚的膨胀的柔性聚氨酯泡沫制成,使得能够使用刀片切割机生产,并且耐受40%压缩率在3.8 和4.8千帕斯卡,从而提供穿透和侧面压缩特性,使得对于上述密度,条带可以在没有粘合剂的情况下保持在凹入接头上。
