International. Advanced Polymer Coatings launched a new triple-resin coating system that combines in a single layer functions that were previously implemented through multilayer systems. The purpose of innovation is to find answers to the challenges of improving efficiency and reducing complexity when using high-efficiency coatings.
In the conventional model, several layers with specific roles are required to protect the surfaces: polyurethane layers that provide resistance to ultraviolet (UV) radiation and gloss, epoxy intermediates that function as a barrier and zinc primers that regulate corrosion.
The new development combines three resins in a single formulation: a polymer based on cyclic polyolefin, which provides impermeability to moisture and chemical resistance, a cycloaliphatic polyurethane, designed to protect against UV radiation and maintain color, and an aliphatic polyaspartic resin, which allows rapid curing and tolerance to variations in humidity and temperature.
According to the company, the secret lies in the simultaneous co-curing of these resins, which prevents compatibility problems and guarantees a uniform film. This procedure makes it possible to obtain "a high cross-linking density, balance between hardness and flexibility, as well as resistance to harsh environmental conditions".
The possibility of being deployed in less controlled field conditions, the decrease in manual work and the elimination of inspections between layers are some of the operational benefits mentioned.
Currently, the system is in the validation phase with comparative tests against traditional multilayer coatings. Tests include corrosion resistance (ISO 12944-6), flexibility (ASTM D522), impact resistance (ASTM D5420), and gloss and color retention in accelerated weathering (QUV).
