    • An apparatus (1) for the application of a composition curable by irradiation to a fastener (2) having a conveyor (3) for conveying fasteners to an application station (5); an application station (10) comprising an applicator from which the composition is dispensed. The conveyor rotates the fasteners past the applicator for application of composition. The same or another conveyor (8) conveys the fasteners to an irradiation station (10) and rotates the fasteners for irradiation thereof. The irradiation station irradiates and thus cures the composition applied to each fastener. The invention also provides a curable composition for application to a threaded article, comprising a dispersion of: (i) components of a first cure mechanism comprising: (a) a (meth)acrylate functional monomer component; (b) a (meth)acrylate functional oligomer component; and (c) a photoinitiator component; (ii) components of a second cure mechanism comprising: (e) an amine component; and (f) an encapsulated epoxy resin component; together with (iii) a thickener component suitable to impart sufficient viscosity to the uncured composition to maintain the dispersion of the other components in the composition; wherein the photoinitiator component is suitable upon irradiation of the composition to achieve a first cure through the depth of the composition applied to a threaded article so that a binder matrix is formed with the components of the second cure mechanism dispersed through the matrix.
    • 一种用于将通过照射固化的组合物施用于具有用于将紧固件输送到施用站(5)的传送带(3)的紧固件(2)的装置(1); 一个施用站(10),包括一个涂抹器,组合物由该涂抹器分配。 输送机将紧固件旋转通过施加器以用于组合物。 相同或另一个输送机(8)将紧固件传送到照射台(10)并旋转紧固件以进行照射。 照射站照射并因此固化施加到每个紧固件上的组合物。 本发明还提供了一种用于螺纹制品的可固化组合物,其包含分散体:(i)第一固化机理的组分,其包含:(a)(甲基)丙烯酸酯官能单体组分; (b)(甲基)丙烯酸酯官能低聚物组分; 和(c)光引发剂组分; (ii)第二固化机理的组分,其包含:(e)胺组分; 和(f)包封的环氧树脂组分; 以及(iii)适于赋予未固化的组合物足够的粘度以保持其它组分在组合物中的分散体的增稠剂组分; 其中所述光引发剂组分适合于组合物的照射,以通过施加到螺纹制品的组合物的深度实现第一次固化,使得形成粘合剂基质,其中第二固化机理的组分分散在基质中。

    • The invention relates to a method of providing a seal between an aluminium substrate and a second substrate, wherein the seal is exposed to engine fluids selected from oils and/or coolant mixtures at elevated temperatures in the range from 600C to 175°C. The method of the invention involves (a) applying to at least one of the substrates an anaerobic sealant composition made from (i) one or more polymerizable (meth)acrylate ester monomers, (ii) an anaerobic cure- inducing component, and (iii) 0.05 to 0.25 % by weight, based on the total composition, of an adhesion promoter comprising one or more phosphorus-containing compounds having the general formula (I), wherein: R 1 is H, CH 3 or C 2 H 5 , R 2 is -CH 2 -C 2 H 4 TC 3 H 6 -, or -CH 2 -CH-(CH 3 )-, R 3 is H, CH 3 or C 2 H 5 , n is an integer from 1 to 10, and m is an integer from 1 to 3; (b) bringing the substrates together face-to-face with a gap between the faces in the range from 0.1 to 0.25 mm, in at least part of the total face-to-face area, and (c) allowing or enabling the composition to cure at substantially ambient temperature.
    • 本发明涉及一种在铝基板和第二基板之间提供密封的方法,其中在600℃至175℃的高温下,密封件暴露于选自油和/或冷却剂混合物的发动机流体。 本发明的方法包括(a)向至少一个基底施加由(i)一种或多种可聚合(甲基)丙烯酸酯单体,(ii)厌氧固化诱导组分和(iii) )0.05至0.25重量%,基于总组合物,包含一种或多种具有通式(I)的含磷化合物的粘合促进剂,其中:R 1是H,CH 2, 或者C 2 H 5,R 2是-CH 2 CO 2, H 2 H 3 - , - CH 2 CH 2 - , - CH 2 CH 2 - , - CH 2 CH 2 - , - (CH 3) - ,R 3是H,CH 3或C H < / SUB,n为1〜10的整数,m为1〜3的整数。 (b)在总面对面区域的至少一部分中,使面对面与面之间的间隙为0.1至0.25mm,并且(c)允许或使组合物 在基本环境温度下固化。
