    • A enamel-free paste for use especially in ovens at temperatures of up to about 420° C. The paste contains a matrix based upon a silicon (Si) polymer that can be obtained by the hydrolysis and condensation of at least one silane of general formula RxSi(OR′)4-x with at least one polysiloxane of general formula [R2SiO]y, or R3Si—(O—SiR2)y—O—SiR3. The radicals R can independently be alkyl, aryl,arylalkyl, alkylaryl or H; the radicals R′ can independently be H, methyl,ethyl, n- or i-propyl, n-, iso-, sec- or tert-butyl; x represents 0 or 1 (for the first silane); x represents 0, 1, 2, 3, or 4 (for each subsequent silane); and y represents a whole number, which is at least 2 and can be approximately infinite. The paste additionally includes a high-boiling organic solvent with a boiling point of 100° C. or above, and a pigment as the solvent, but does not include alcohol with a boiling point of below 100° C.
    • 一种不含搪瓷的糊剂,特别是在高达约420℃的温度下在烤箱中使用。糊料包含基于硅(Si)聚合物的基质,其可以通过至少一种通式 R x Si(OR')4 x x与至少一种通式[R 2 SiO] SiO 2的聚硅氧烷 或者R 3 Si-(O-SiR 2)n -O-SiR 3 3。 基团R可以独立地为烷基,芳基,芳烷基,烷基芳基或H; 基团R'可以独立地为H,甲基,乙基,正或异丙基,正,异,仲或叔丁基; x表示0或1(对于第一硅烷); x表示0,1,2,3或4(对于每个随后的硅烷); y表示整数,至少为2,可以近似为无穷大。 该糊料还包括沸点为100℃以上的高沸点有机溶剂和作为溶剂的颜料,但不包括沸点低于100℃的醇。
