Two-component anticorrosive coating formulation

Introduction

The two-component anticorrosive coating has strong adhesion and excellent physical properties, as well as excellent oil resistance, water resistance, acid and alkali resistance, salt spray resistance and temperature resistance; it can be applied throughout the year, even at temperatures as low as -15°C.

Application field

The two-component anticorrosive coating is mainly used as a general-purpose primer, suitable for all main parts of ships; suitable for different substrates, such as steel, aluminum, stainless steel, etc.

When the two-component anticorrosive coating is used for anticorrosion treatment, it is necessary to first mix the A component and the B component according to a mass ratio of about 10:1, and then apply various methods such as spraying, brushing, etc.
