【NETIS Registration Technology】 KK-240019-A Water-soluble rust conversion type anti-rust primer for East, Central, and West Japan Expressway Co., Ltd. Structural construction management guidelines, rebar anti-rust material, performance verification compliant product. *We propose a cross-section repair method as the "Reprocrete Method."* Reprochange Coat is a water-soluble rust conversion type anti-rust primer that converts red rust on rebar and other materials, which could not be completely removed by scraping, into stable black rust through a chemical reaction, thereby suppressing the progression of rust. <Features> 1. Workability ● It is a straight type, so it can be used directly on-site without dilution. ● It is a single-component product that is easy to handle, making it suitable for use as a protective material for rebar in a rust-prone state after scraping. 2. Adhesion ● It has good adhesion with Repro Mortar AZ and does not hinder adhesion even when used in conjunction with Repro anti-rust paste. 3. Anti-rust properties ● By converting red rust (hydrated iron oxide) on rebar and other materials into black rust (iron tetroxide) using a special acid, it suppresses the progression of rust. ● Since it contains acrylic resin, it can be applied to rust-free rebar and other materials, forming a film that provides anti-rust effects.
