Waterborne polyurethane topcoatTMJ2K-M4

Application Range:This productWidespreadShouldForA variety of machinery and equipment.Protection of metal surfaces such as stainless steel, aluminum alloy, galvanized plate, iron, etc.CoatingDecorative，And protective coatings for existing structural repairs and new structural anti-corrosion systems, including oil, gas, and water pipelines, as well as gas cylinders.

Composition and Performance:ThePaintIt is a two-component mixed paint, separated into varnish.ACuring agentBAll are ground from modified resins, cross-linking agents, pigments, etc., and can be dried naturally or baked.。

1. The coating boasts excellent adhesion, with superior bonding strength on steel, galvanized steel, and light metals.

2. Excellent resistance to alternating dry and wet conditions, oil resistance, superior three-proof performance, and resistance to humidity and heat.

3. Drying fast, resistant to water, acids, alkalis, and salts, with excellent physical and mechanical properties; the film can be baked at low temperatures.

4. High fullness, aging resistance, and film-forming properties.

Construction Methods and Precautions

1、Construction ratio (weight ratio): PaintA: Binder to Pure Water = 100:25; 25~75

2、AAfter opening the drum of components, they must be thoroughly mixed, then, while stirring, they should be mixed according to the required proportions.BGroupCopyPouredAIn the composition, fully              Mix thoroughly, let stand, mature30 minutesThen, add a sufficient amountPure WaterAdjust to construction viscosity.

3、Construction Method∶Spraying, Brushing，Roll Coating;

4、Substrate temperature must be above the dew point3Above 5℃, when the base material temperature is below 5℃, the coating does not cure, therefore it is not suitable for application.。

5、Dry Conditions∶Room temperature self-drying or drying60~100°C）X（30Minute(s)

6Note: Ensure that the anti-rust primer and intermediate coat are fully cured, and the surface is clean, dry, and free of contaminants before applying the topcoat. Coating over uncured primer or intermediate coat may sometimes cause color bleeding, pinholes, and other unknown defects.

Packaging and Storage：

1、Standard Packaging∶ 4kg/Bucket 20kg/Bucket  Curing agent:1kg/Barrel2kg/Drum

2、Store5-30Store in a dry, well-ventilated area; shelf life will significantly shorten under high temperatures or exposure.
