Comprehensive Solution for Assessing the Breathability of Organosilicon Elastic Coating

Organosilicon Elastic Coating often referred to as silicone elastomeric coatings, is a type of coating material that utilizes organosilicon compounds as its primary component. These coatings are known for their exceptional elasticity, durability, and resistance to various environmental factors.

Organosilicon elastic coatings have found widespread applications in construction due to their unique properties. Some common uses include roof coating, exterior wall coating, bridge Coating and industrial coating, they are used to coat equipment, buildings and infrastructure providing corrosion protection and improving overall performance.

Organosilicon Elastic Coatings have properties such as Elasticity, Weather Resistance, Waterproofing and Breathability. To ensure the quality and performance of organosilicon elastic coatings, several tests should be considered to evaluate their properties such as elasticity, weather resistance, waterproofing and Breathability.

Breathability is a crucial property of organosilicon elastic coatings, as it allows moisture vapor to pass through the coating, preventing condensation and mold growth. To assess the breathability of these coatings, certain tests should be employed.

Water Vapor Transmission Rate (WVTR) test measures the rate at which water vapor can pass through a specified area of the coating under controlled conditions. ASTM E96 and ISO 250 are commonly used standards for WVTR testing.

Labthink C403H and C406H Oxygen /Water Vapor Transmission Rate Test Systems are based on the testing principle of Coulometric oxygen sensor and infrared water vapor sensor. They are equipped with high-precision temperature and humidity sensor, to monitor and record temperature and humidity changes in real time, ensuring stable test conditions. The instruments have high test repeatability of 0.01 cc / (m2·day), provide accurate and precise measurements. They are designed according to ASTM D3985, ASTM F1249, ISO 15106-2 and other relevant standards. In addition, the instruments can test OTR and WVTR, and with high quality sensors, have Longer service life.

Beside the WVTR test manufactures should also test their adhesion to the substrate to prevent peeling or delamination, the thickness of films to which the coating should be applied and other applicable tests.

By conducting these tests, manufacturers and applicators can evaluate the breathability of organosilicon elastic coatings and select appropriate products for applications where moisture vapor management is critical.

As the demand for functional packaging materials grows, testing methods are evolving to ensure a more comprehensive evaluation of packaging films. Labthink encourages collaboration with packaging industry companies for quality control! Visit the website www.labthink.com to learn more!
