825-Cleanthane 2100 Exposed Polyurethane Waterproof Intermediate Coating

Product Introduction:

This product is a solvent-free two-component elastic polyurethane coating system with excellent chemical resistance and mechanical strength. It is particularly suitable for waterproofing concrete roofs, offering good self-leveling properties, superior waterproofing, high elasticity, and the ability to form a single-layer thick film (approximately 3 mm). After complete reaction, the product forms a medium-hardness coating, making it a high-grade elastic waterproofing material that meets KS F 3211 Class 1 Exposed Elastic Polyurethane Waterproofing Material Standard (Polyurethane Rubber Category ). The product is free of toxic substances and heavy metals, environmentally friendly, cures at room temperature, and is easy to repair damaged waterproofing layers.
Note: KS F 3211 polyurethane rubber series Class 1 standard primarily targets "exposed" elastic waterproof materials. This means that KS F 3211 standard products are designed for direct exposure to weather conditions such as sunlight, rain, and temperature variations. Therefore, these materials must possess excellent weather resistance and durability.

characteristic:

1. Excellent waterproof performance: Polyurethane coatings can form a dense and continuous waterproof membrane on the surface, effectively preventing moisture penetration.

Its high elasticity allows it to adapt to minor deformations in the building structure, preventing leakage caused by cracks.

2. High elasticity and toughness: Polyurethane coatings have excellent elasticity and toughness, and can maintain flexibility even at low temperatures, making them less prone to cracking.

This allows it to withstand the thermal expansion and contraction and vibration of the building structure, maintaining the integrity of the waterproof layer.

3. Weather resistance and durability: Polyurethane coatings have excellent weather resistance and can resist the erosion of natural factors such as ultraviolet rays, ozone, and acid rain. They are highly durable, have a long service life, and reduce the frequency of maintenance and replacement.

4. Strong Adhesion: Polyurethane coatings can firmly adhere to various substrates, such as concrete, metal, and wood. This ensures a tight bond between the waterproof layer and the substrate, improving the waterproofing effect.

use:

1. Suitable for waterproofing projects in apartments, building roofs and other areas.

2. Waterproofing materials used in various civil engineering projects, building roofs and related parts.

3. Suitable for waterproofing concrete surfaces, especially as an intermediate coating in exposed roof waterproofing systems.

construction:

Tools: Toothed scraper, rubber scraper, rake, roller

Dry film thickness: Adjustable as needed

Construction conditions: Concrete must be cured for at least 28 days in an environment with an air temperature of 21 degrees Celsius and a relative humidity of 50%.

Cleaning: After using all tools, please clean them thoroughly with the recommended thinner.

If dilution is required, please use the provided thinner.

For walls with different degrees of chalkiness, the dilution ratio can be adjusted appropriately according to their paint absorption capacity and the number of coats applied.

Instructions for use:

Surface treatment

Concrete needs to be cured for at least 28 days in an environment with an air temperature of 21 degrees Celsius and a relative humidity of 50%.

Before construction, moisture, grease, old or damaged coatings, and other contaminants must be removed from the surface.

If there are any cracks on the surface, please use Cleanthane 1000 to add fiberglass repair.

For coarse cracks or fissures, as well as the junction of walls and floors, reinforce with Cleanthane 2100 and grout ( 7:3).

Paint preparation

Stir well before use, and mix thoroughly with the hardener as recommended in the instructions.

Under normal circumstances, no thinner needs to be added (if necessary, a matching thinner can be added, but the amount added should be less than 5% ).

Storage:

Storage period: 6 months

This product must be stored in a cool, dry, and well-ventilated place, away from direct sunlight and fire.

Notes:

Please read the paint instructions carefully before application.

The paint should be thoroughly stirred after opening the can.

Strictly follow the dilution ratio specified in the instructions; do not dilute excessively.

Please mix the main agent and hardener thoroughly according to the proportions indicated in the instruction manual.

Any grease, moisture, or dust on the construction surface must be thoroughly cleaned, and the moisture content of the substrate must be less than 8%.

This product is flammable and should be kept away from heat sources and open flames.

The work area should be well-ventilated during construction, and workers should avoid contact with skin and eyes. Please refer to SDS for relevant information.

Do not use when the temperature is below 5 °C or the relative humidity exceeds 85%.

Unused main agent and hardener should be sealed separately and stored in a cool place.

Gray and light-colored products may fade or change color over time or during application due to exposure to ultraviolet radiation. This is a normal reaction and does not affect the quality or performance.
