    • A composition and method for providing temporary masking of electrical and electronic components compatible with a high speed production operation. The composition is a radiation curable viscous liquid composition which provides minimal adhesion properties and substantial cohesive properties so that when cured, it can be readily removed in the manner of an adhesive tape. In particular, the radiation curable composition is characterized by cured properties a) of positive adhesion to the substrate to which the composition is applied, but insufficient adhesion to resist peeling forces applied by hand; and b) of sufficient cohesive strength to allow substantially all of the cured composition to be stripped mechanically or by hand in a single piece. Suitably the adhesion of the cured composition (22) to the substrate (16) as measured in the tensile shear mode, is between about 5 and 55 psi. This level of adhesion is sufficient to prevent ingress of solvent solder, plating or coating materials but low enough to allow easy dry stripping mechanically or by hand.
    • 一种用于提供与高速生产操作兼容的电气和电子部件的临时掩蔽的组合物和方法。 组合物是可辐射固化的粘性液体组合物,其提供最小的粘合性能和显着的内聚性能,使得当固化时,可以以粘合带的方式容易地除去。 特别地,可辐射固化组合物的特征在于固化的性质a)对其施加组合物的基材具有良好的粘合性,但是对用手施加的剥离力的粘附性不足; 和b)具有足够的内聚强度以允许基本上所有的固化组合物机械地或手工地剥离成一体。 适当地,在拉伸剪切模式下测量的固化的组合物(22)对基材(16)的粘附性在约5和55psi之间。 这种粘附程度足以防止溶剂焊料,电镀或涂层材料进入,但足够低以容易地机械地或手工干燥剥离。
