Copper Mesh (Stencil) Cleaner - KT-702

Kootai KT-702 is a neutral pH, deionized water-based cleaning solution designed to effectively dissolve uncured red adhesive and solder paste residues on steel, copper, and plastic mesh stencils used in SMT processes. Powered by a specialized blend of surfactants and additives, it penetrates fine-pitch apertures and cleans quickly, leaving no white residue, enabling uninterrupted printing operations.

This environmentally compliant cleaner is non-flammable, does not emit VOCs, and does not require explosion-proof environments, making it safe and easy to use in high-volume production. It evaporates slowly, ensuring long service life, and is especially effective for thick adhesive residue that standard water-based products struggle with.
