Introduction to ZS-211 Reflective Thermal Insulation Coating and Explanation of Indoor Moisture Resistance Effect（New application of insulation coatings for interior and exterior walls of buildings）

1、 Introduction to ZS-211 Reflective Thermal Insulation Coating Core

1.1 Product positioning and core attributes

ZS-211 Reflective Thermal Insulation Coating is a room temperature space energy-saving thermal insulation coating, which belongs to the single component modified inorganic water-based coating that prevents heat conduction. It has the core advantages of "thin layer efficiency and multifunctional integration". Its appearance is a bone white thick paste, with a specific gravity of only 0.46g/ml after solidification, a solid content of over 85%, and a temperature resistance of up to 150 ℃. It can be widely used in internal and external surface insulation projects in various fields such as construction, chemical industry, metallurgy, transportation, etc., especially suitable for the energy-saving and protection needs of indoor environments in buildings.

The core highlight of the product lies in its multiple functions of thermal insulation, decoration and waterproofing, mold and corrosion prevention, insulation and fire prevention, and no VOC volatilization throughout the process. It is a non-toxic and harmless green environmental protection material that meets the environmental protection requirements of indoor living environment.

1.2 Core components and working mechanism

The coating is composed of modified solution, uniformly sealed nano hollow glass microspheres with a mesh size of 80 or more, heat reflecting material, ceramic fibers and other core components. Its insulation and heat preservation mechanism is derived from the dual structure design of "static air insulation+inorganic insulation shielding": after coating, the coating will form a three-dimensional network hollow structure connected by hollow glass microspheres, and a large number of static air groups (i.e. insulation and heat preservation units) are formed between the microspheres. These static air hardly generate heat convection when heated, greatly reducing the heat conduction efficiency; At the same time, pure inorganic materials are used as coating support, combined with heat reflecting substances to assist, making the thermal conductivity of the coating as low as 0.033W/m · K, close to the vacuum thermal conductivity, with an insulation level of R-27, and a thermal insulation suppression efficiency of about 90%, which can effectively prevent indoor and outdoor heat exchange.

2、 Detailed explanation of indoor moisture-proof effect of ZS-211 reflective thermal insulation coating（New application of insulation coatings for interior and exterior walls of buildings）

2.1 Core moisture-proof mechanism

The moisture-proof effect of ZS-211 in indoor environments is derived from the triple protection logic of "anti condensation, moisture isolation, and strong adsorption":

Inhibiting condensation: One of the core reasons for indoor wall moisture is that the wall temperature is lower than the dew point temperature of the air, causing water vapor in the air to condense on the wall. The excellent thermal insulation performance of coatings can effectively maintain the stability of wall surface temperature, avoid low wall temperature, and reduce the formation conditions of condensation water from the root.
Physical moisture barrier: The cured coating forms a dense three-dimensional network structure, which can effectively isolate the penetration of water vapor in the air, prevent water vapor from entering the interior of the wall, and prevent the wall from becoming damp, softening, or breeding mold.
Adsorption purification assisted moisture-proof: The microporous structure in the coating has strong adsorption performance, which can adsorb and fix some harmful gases and free water vapor in the indoor environment in the pores, further optimize the indoor humidity environment through neutralization reaction, and assist in improving the moisture-proof effect.

2.2 Practical application of moisture-proof effect guarantee

In practical indoor application scenarios, the moisture-proof effect of ZS-211 is enhanced through multiple performance guarantees:

Anti fungal ability: reaching level 10 of ASTM D-3273-73T standard, it can effectively inhibit the growth of mold and bacteria in humid environments, avoid problems such as mold spots and odors on walls, especially suitable for indoor spaces with high humidity such as bathrooms, kitchens, and basements.
Small crack coverage and waterproof leakage: Coatings can cover small cracks on the surface of walls, forming a continuous waterproof coating that effectively blocks the penetration of small amounts of water seepage or condensation, further consolidating the moisture-proof effect and protecting the wall substrate from water vapor erosion.
Temperature regulation assisted moisture prevention: Through efficient thermal insulation performance, the coating can maintain a relatively stable indoor temperature, reduce wall temperature fluctuations caused by day night temperature differences or seasonal changes, lower the probability of water vapor condensation caused by temperature differences, and maintain a dry indoor environment for a long time.

Actual test data shows that in indoor environments where condensation is prone to occur (such as basements and north facing walls without natural lighting), applying a 2mm thick ZS-211 coating can effectively prevent condensation from occurring. The walls remain dry for a long time without any signs of dampness or mold.

2.3 Construction precautions for indoor moisture-proof applications

To ensure the indoor moisture-proof effect, the following key points should be followed during the construction process:

Construction environment: Construction should be carried out in a ventilated and dry environment with a relative humidity of less than 60% and a temperature above 10 ℃; If the environmental humidity is high and the temperature is low, a heat source can be used for heating and curing, but the surface temperature of the coating should not exceed 70 ℃ to avoid vaporization bubbles that affect the continuity of the moisture-proof coating.
Construction method: Brushing, rolling, wiping or spraying (airless high-pressure spray gun) can be used, and the coating should be thoroughly mixed before construction; When the coating thickness is greater than 0.5mm, it is recommended to use multiple layers of construction. The thickness of the first layer should be controlled at around 0.3mm, and the thickness of each subsequent layer should not exceed 1mm. The next layer should be applied after the surface of the previous layer has dried (at room temperature for ≥ 30 minutes), and the brushing direction should be perpendicular to the previous layer.
Substrate treatment: Before construction, it is necessary to ensure that the wall substrate is flat, dry, and free of oil and dust. If the substrate has a large area of moisture or leakage, it needs to be treated with basic waterproofing before painting.

3. Summary

ZS-211 reflective insulation coating, with its advantages of green environmental protection, efficient insulation, and multifunctional integration, not only meets the needs of indoor energy-saving insulation, but also provides stable and reliable moisture protection for indoor environments through the triple mechanism of "anti condensation, moisture insulation, and strong adsorption", effectively solving problems such as wall moisture and mold. Its convenient construction and adaptability to various indoor spaces make it the preferred material for energy-saving and moisture-proof protection in building interiors, with practical value and improved living comfort.
