摘要： There is disclosed is a method comprising surface-processing a Sn based, Sn alloy based or Sn-Zn alloy based solder particle (1), applied as a coating, such as by electrical plating or melt plating, to the surface of a metal material, such as iron, a steel plate or copper, with a phosphate and a silicium containing compound, to form a protective film (2). There are also disclosed a solder material (6) in which a protective film (2) formed of a phosphate and a silicium containing compound is formed on the surface of the Sn-Zn based solder particle (1), and a solder paste formed of this solder material (6) and the flux.

摘要： A metal surface treatment agent comprising the following components (A) to (D), which securely adheres to a metal substrate such as aluminum, exhibits excellent corrosion preventive properties even with a thin film thickness, and has excellent plasticity and adhesion to paints. (A) at least one type of organosilicon compound having three carbonyl groups and at least one alkoxysilyl group, in a weight ratio of 5 to 15 when the total of the components (A) to (D) is 100; (B) at least one type of epoxy resin modified with an alkanolamine, in a weight ratio of 10 to 30 relative to the above total; (C) at least one blocked polyisocyanate, in a weight ratio of 50 to 70 relative to the above total; and (D) at least one type of amino resin in a weight ratio of 5 to 15 relative to the above total.
