Application of Polyaspartic Resin in the DTM Sector
To understand the application of Polyaspartic Resin in the DTM (Direct to Metal) sector, we first need to define what DTM is. DTM, a term specific to the industrial coatings industry, means 'direct to metal,' which refers to anti-corrosive coatings applied directly to metal surfaces. This is one of the main application areas of Polyaspartic Polyurea Resin.
Anti-corrosive coatings are applied to metal surfaces to protect them from corrosion. They are widely used in aviation, shipbuilding, chemical industries, oil pipelines, steel structures, bridges, and oil drilling platforms, and are highly favored by construction manufacturers.
With the growing scarcity of non-renewable resources such as oil and coal, and the increasing awareness of environmental protection, the coatings industry is gradually shifting towards sustainability and resource conservation. Before the mid-20th century, solvent-based coatings were extensively used in various constructions, industrial products, and steel anti-corrosion coatings, resulting in significant VOC emissions into the atmosphere. This caused severe air and water pollution, which adversely affected human health.
The demand for environmentally friendly coatings is increasing, along with the need for anti-corrosive coatings. Increasing the solid content of anti-corrosive coatings to reduce VOC emissions has become a key priority in the coatings industry. Polyaspartic Resin, used in anti-corrosive coatings, offers significant advantages in coating engineering machinery and specialized containers. Its features include high solid content, low viscosity, excellent weather resistance, rapid drying without the need for baking, and energy efficiency. This not only conserves energy and protects the environment, but also provides exceptional durability. ISO 12944-2018, the international standard for anti-corrosive coatings on steel structures, now includes Polyaspartic(polyaspartic ester) coatings, alongside polysiloxane and fluoropolymer coatings, suitable for C5 and higher environments.
Furthermore, unlike traditional materials such as foam glass bricks, glass flake, OM coatings, or mastic, it offers high hardness, long service life, and excellent weather resistance, lasting for over 10 years. With very low viscosity and low VOC emissions, its preparation, application, and coating formation cause no environmental pollution.
