MT 650 Chlorinated Rubber Topcoat

Product Introduction:

This product is a high-performance, single-component chlorinated rubber topcoat, formulated with specially selected chlorinated rubber resins and a blend of highly weather-resistant pigments and additives. Its formula is specifically designed for long-term protection and decoration, requiring no hardener for direct application, making it simple and quick to apply. The coating dries rapidly and provides excellent weather resistance, chemical resistance, and water resistance, making it an ideal protective coating for metal and concrete surfaces in moderately to heavily corrosive environments.

characteristic:

1. Excellent weather resistance: The paint film can effectively resist the erosion of natural environment such as ultraviolet rays, acid rain, and temperature changes. It is not easy to chalk, discolor or crack, and maintains its beauty for a long time.

2. Excellent chemical resistance: It has good resistance to acids, alkalis, brine, seawater, mineral oils and some chemicals, and is particularly suitable for environments where chemicals are exposed.

3. Excellent water resistance: The paint film has strong waterproof performance, which can effectively prevent moisture penetration and prevent the substrate from rusting or deteriorating.

4. Easy to apply: Single-component packaging, no mixing required, can be applied by spraying, brushing or rolling, easy to operate and dries quickly.

5. Good adhesion: It has good bonding strength to pre-treated steel and concrete surfaces and matching primers.

6. Tough paint film: The paint film has stable physical properties and a certain degree of flexibility and wear resistance.

use:

This product is widely used on metal and concrete surfaces requiring high weather resistance, water resistance, and chemical resistance. Its main applications include:

1. Industrial facilities: Steel structures, equipment and pipelines suitable for facilities such as chemical plants, power plants, and sewage treatment plants.

2. Bridges and Wharves: Used for bridge steel structures, wharf facilities, breakwaters, and other places that are exposed to humid or salt spray environments for a long time.

3. Municipal engineering: Applicable to outdoor public facilities such as streetlights, traffic signs, guardrails, and underground pipelines.

4. Tanks and Piping: The outer walls of tanks and piping systems used to store water, oil or chemicals.

5. Concrete protection: Can be used for concrete bridge piers, retaining walls, etc., to provide protection and decorative effects.

It is recommended that the coating thickness be at least three times the maximum roughness (Rz) to achieve a good protective effect.

Instructions for use:

Surface treatment requirements:

Use a solvent to remove visible grease, oil, lubricants, cutting fluid, and other soluble contaminants from the metal surface that may affect adhesion, or use other methods to prepare the surface condition for the coating application, following the SSPC-SP1 surface treatment standard to prepare for subsequent protective coating applications.

The steel structure surface must be sandblasted to Sa2.5 (very thorough sandblasting) or SSPC-SP10 grade. Without using a magnifying glass, at least 95% of the surface area should be free of any visible oil, grease, dust, dirt, scale, rust, coatings, oxides, corrosion products, and other foreign matter. The surface roughness should be in the range of Rz 30-75μm.

Power tool treatment must meet St 3. This standard defines the use of power tools (such as power wire brushes, grinders, abrasive discs, etc.) to remove loose rust, scale, old coatings, and other foreign matter from steel surfaces until the surface has a metallic sheen. However, minor scratches and discoloration are permissible. It is equivalent to SSPC-SP3 in the US SSPC standard.

Surface defect treatment: This includes weld slag, burrs, cracks, and holes. These defects affect the adhesion and protective effect of the coating and should be removed or repaired as much as possible.

After surface treatment, a thorough inspection should be conducted to ensure that there are no contaminants or defects such as oil, grease, dust, dirt, scale, rust, welding slag, or burrs before proceeding with the next step.

Under any atmospheric conditions, it is best to perform the coating work within 1 hour after the completion of the "surface treatment" procedure, and no later than 8 hours after the "surface treatment".

Different coatings have different requirements for surface cleanliness and roughness. Please discuss this in detail with our sales staff before using this product.

Construction environment requirements:

Coating application should be carried out under suitable environmental conditions to ensure the quality of the coating. The following factors should be considered:

Temperature: Please construct within the recommended temperature range. Generally, it is not advisable to construct in environments below 5℃ or above 40℃.

Humidity: Relative humidity should not exceed 85%. Avoid construction in humid or rainy weather.

Wind speed: Excessive wind speed will affect the spraying effect; avoid construction on windy days.

Surface temperature: The surface temperature of the steel should be at least 3°C ​​higher than the dew point temperature to avoid condensation on the surface.

Storage:
