Sodium lauryl sulfate (K12) is white or light yellow powder or liquid with a slight greasy smell. Easily soluble in water, it can reduce the surface tension of aqueous solutions and emulsify oils and fats. It is not sensitive to alkali and hard water, and has good compatibility with anions and non-ions. This product is flammable, irritating, and sensitizing. It is flammable when exposed to open flames and high heat. It decomposes when heated to release toxic gases.
Sodium lauryl sulfate (K12) is a surfactant that can play a wetting role:
Sodium lauryl sulfate (K12) is an anionic surfactant used in electroplating processes such as bright nickel and nickel alloys as a wetting agent ( Also known as anti-pinhole type) The long-chain alkyl group in its structure is hydrophobic, which can reduce the surface tension of the plating solution, causing the hydrogen bubbles generated by the cathode during the electrodeposition process to quickly leave the cathode surface and prevent the formation of pinholes in the coating.
Sodium lauryl sulfate (K12) is an anionic surfactant C12H25. The lipophilic group is a non-polar group and strives to penetrate into the solution. In another phase of the organic solution, oil and solid phase, the surface active molecules are directionally arranged on the interface layer.
Sodium lauryl sulfate (K12) can reduce the surface tension of the plating solution and play a wetting role. Surface tension is the surface tension of the liquid on which the molecules on the surface are attracted by the molecules inside, causing the surface to shrink and the surface to the liquid. The direction of surface tension is tangent to the liquid surface and perpendicular to the interface between parts.
