Weather Proof Double Layer Epoxy Compound Powder
Introduction
The product is a kind of weather proof double layer heavy duty epoxy compound powder, comprises of two layers of primer and finishing, to be applied directly to steel surface after sandblasted and heated. The primer layer is to provide protection for anticorrosion. The finishing layer is anti- scratch, anti-impact, anti-abrasion as the common advantage of epoxy coating, it is also featured with high shinning, UV-resistant, and superior durable, heat resistant, anti-corrosion, anti-powderization. The finishing layer is applied onto the primer layer. Two layers of powder are melted and solidified to an even, dense coating layer with solid jointing between two layers. The powder can be customized to a plenty of color with can’t be get from normal anti-corrosion layer. the coating will not fade, darken fast over time, even for the bright colors like white, light blue, pink, bright yellow, etc.
The coating is mainly used for anti-corrosion protection of oil and gas, municipal piping line, etc.
Feature
Excellent UV resistant and weather proof performance.
No need to apply primer painting before applying the coating.
Easy application, fast solidification, high working efficiency, suitable for working on coating line.
Coating has superior flexibility, toughness and anti bending performance. Easy for quality inspection.
Application Requirements
Powder to be applied to surface by high pressure electrostatic spraying.
Powder spray thickness: Primer layer (EPY2-VD) ≥ 300 μ m, finishing layer: (PPY2-VM)≥300μm, total thickness ≥600μm.
Average quantity: Primer layer (EPY2-VD)420g/m2, finishing layer: (PPY2-VM)420 g/m2.
Surface treatment: stand blasting or grit blasting.
Solidification condition: Primer layer (EPY2-VD)：（190～220）℃（/2~4）min, finishing layer: (PPY2-VM)：（190～220）℃/（2~3）min.
Solidification instruction: the powder shall be applied to pre-heated workpiece, solidified by remaining heat, reheating is normally not required unless wall thickness is too less or working temperature is too low.
