Polyurethane catalyst TMR-2 and AATCC 15 sweat corrosion test in smart wear

In the wave of modern technology, smart wearable devices are being integrated into our daily lives at an unprecedented speed. From fitness trackers to smart watches, these small but powerful devices not only bring convenience to our lives, but also become a symbol of the combination of fashion and technology. However, behind this prosperity, there is a problem that cannot be ignored – sweat corrosion. This is not only a test of the durability of the device, but also a challenge to the user experience. In this contest on durability and performance, the polyurethane catalyst TMR-2 quietly came on the stage, providing a solid line of defense for smart wearable devices with its excellent performance.

Introduction: The Collision of Sweat and Technology

Imagine a scene where you run in a morning with a new smart bracelet, sweat slid down your forehead and dripped onto the bracelet. At this time, you may not realize that your sweat is quietly eroding the surface of this high-tech product. That’s why AATCC 15 sweat corrosion testing has become so important. This test is designed to evaluate the corrosion resistance of materials in a simulated sweat environment, ensuring that smart wearable devices can maintain their function and appearance in a variety of environments.

In this field, the polyurethane catalyst TMR-2 has become a key factor in improving the sweat corrosion resistance of smart wearable devices due to its unique chemical properties and excellent catalytic effects. This article will explore in-depth the application of TMR-2 in smart wearable devices and how it proves its value through the AATCC 15 test.

Detailed explanation of AATCC 15 sweat corrosion test

Test Method

AATCC 15 Sweat Corrosion Test is a test designed specifically to evaluate the corrosion resistance of textiles and related materials under simulated human sweat conditions. The test evaluates the durability of the material by exposing the sample to a synthetic sweat environment and monitoring its changes over a certain period of time.

The test process usually includes the following steps:

Sample Preparation: Cut the material to be tested to a specified size.
Sweat Preparation: Prepare artificial sweat according to standard formulas, usually containing sodium chloride, lactic acid and other electrolytes.
Sample Immersion: Soak the sample completely in artificial sweat.
Observation and Recording: Take out the sample within a specific time interval, observe and record its surface changes.

Result Analysis

Analysis of the test results can be obtained by obtaining the corrosion conditions that the material may encounter in the actual use environment. For example, some materials may experience color changes, surface peeling, or mechanical properties. This information is essential for improving product design and choosing the right materials.

The application of TMR-2 in smart wearable

Improving corrosion resistance

In smart wearable devices, the application of TMR-2 is mainly reflected in improving the sweat corrosion resistance of polyurethane coatings. By accelerating the curing process of polyurethane, TMR-2 can form a denser and more stable coating structure, effectively blocking sweat from erosion of internal components of the device.

Improve user experience

In addition to technical levelThe advantage of this is that the use of TMR-2 also directly improves the user’s experience. More durable equipment means users do not need to change accessories frequently, and also reduces inconvenience and additional expenses caused by equipment damage.
