When choosing coating or sealing materials, people often struggle with the dilemma of "choosing hardness or flexibility"—materials that are too hard are prone to brittleness and cracking, while those that are too soft may deform. However, IOTA M20-50W-0 mold-proof special addition-type silicone rubber can achieve both hardness and flexibility, and also has a built-in super strong mold-proof property, making it a preferred material for multiple scenarios.
It adopts a two-component design (Component A and Component B), which can be used after mixing in a certain ratio. Component A is transparent and has low viscosity, facilitating uniform mixing with Component B. The color of Component B can be adjusted and customized according to the product appearance requirements, meeting different aesthetic needs. The mixed material has a moderate viscosity. Whether it is doctor-bladed on the surface of a flat substrate with tools or used for overall coating by immersing small products in it, it can cover evenly without uneven thickness, adapting to various construction methods.
"Mold-proof" is one of its highlights. It can effectively prevent mold growth, and is especially suitable for mold-prone environments such as humid and dark places, such as protective coatings in basements and sealing strips in bathrooms, allowing products to get rid of the trouble of "mildew and blackening". What's more remarkable is that it achieves "a combination of rigidity and flexibility" in performance: after curing, it has moderate hardness, which can not only support the product shape but also avoid cracking when dropped like hard plastic. It has excellent tensile and tear resistance, and can flexibly cope with slight collisions and pulls in daily use without easy damage.
From the perspective of specific data, its tensile strength is ≥4 MPa, which is equivalent to being able to withstand a force of about 40 kg acting on an area of 1 square centimeter without breaking, showing its remarkable durability. The elongation rate is ≥200%, which means that a material originally 10 cm long can be stretched to more than 30 cm without breaking, and its flexibility is far superior to ordinary hard materials. The tear strength is ≥10 kN/m, so even if there are small scratches on the surface, it is not easy to crack further, greatly reducing maintenance costs.
In practical applications, its performance is very outstanding. As a mold-proof special adhesive, it can be used for sealing gaps in home appliances and furniture, which can not only prevent dust and moisture from entering but also avoid mold growth. It can be used to make doctor-bladed protective layers, which are applied to the surfaces of outdoor equipment and tools to resist aging caused by wind, sun and rain and prevent mold erosion. It can also be used to produce dip-coated products, forming a complete protective film on the surface of small parts, which is mold-proof, scratch-resistant and durable. Whether in humid indoor scenarios or daily scenarios with slight external forces, it can perform stably.
This silicone rubber, which combines mold-proof, hardness and flexibility, breaks the "single limitation" of material performance, provides a flexible solution for material needs in different scenarios, and enables products to achieve dual breakthroughs in practicality and user experience.
