摘要： Coupling of block base copolymers terminated by a lithium atom of the typical formula S-B-Li, in which S is a monovinylaromatic hydrocarbon block and B is a conjugated diene block, by the use of at least one difunctional deactivating coupling agent and at least one polyfunctional deactivating coupling agent in a molar ratio such that the linear polymer obtained by coupling represents 65 to 95 % by weight of the total polymer material obtained by coupling.

摘要： A shop primer composition comprising (i) fillers and pigments, at least 25 wt % of which have conductive properties; (ii) zinc powder in a weight ratio of between 1:6 to 1:1 to the fillers and pigments; said zinc, fillers and pigments being milled to a sufficient fineness; (iii) anti-settling agents; (iv) optionally, thickening agents; (v) a silicate-type binder, in an amount such that the weight ratio of the SiO2 content of said binder to the zinc, fillers and pigments is of from 1:4 to 1:16; and (vi) solvents. When using this shop primer composition, the welding properties are improved and the health hazards during welding are reduced, without having to remove the primer layer at the welding area. The primer coatings are compatible with the welding techniques generally used in the heavy steel construction industry, including MIG/MAG welding in 3F position.
摘要翻译：一种车间底漆组合物，其包含（i）至少25重量％具有导电性能的填料和颜料; （ii）与填料和颜料的重量比为1：6至1：1的锌粉; 所述锌，填料和颜料被研磨成足够的细度; （iii）抗沉降剂; （iv）任选的增稠剂; （v）硅酸盐型粘合剂，其量使得所述粘合剂的SiO 2含量与锌，填料和颜料的重量比为1:4至1:16; 和（vi）溶剂。当使用该车间底漆组合物时，焊接性能得到改善，并且焊接时的健康危害降低，而不需要在焊接区域去除底漆层。底漆涂层与通常用于重型钢结构工业的焊接技术相兼容，包括3F位置的MIG / MAG焊接。
