Application of thermosensitive catalyst SA-102 in outdoor polyurethane products

1. Introduction

Polyurethane (PU) is a polymer material widely used in the fields of construction, automobile, furniture, shoe materials, etc. Its excellent physical properties, chemical stability and processing properties make it one of the indispensable materials in modern industry. However, when used outdoors, polyurethane products often face challenges such as ultraviolet rays, temperature changes, and humidity, resulting in aging of materials and degradation of performance. In order to overcome these problems, the thermal catalyst SA-102 was born and became a key additive to improve the performance of outdoor polyurethane products.

This article will introduce in detail the application of the thermal catalyst SA-102 in outdoor polyurethane products, including its working principle, product parameters, application cases and future development trends.

2. Working principle of the thermosensitive catalyst SA-102

2.1 Definition of thermally sensitive catalyst

Thermal sensitive catalyst is a catalyst that is capable of activating or inactivating within a specific temperature range. Its catalytic activity varies with temperature, usually with lower activity at low temperatures, while its activity is significantly enhanced at high temperatures. This characteristic makes the heat-sensitive catalyst have important application value in the production process of polyurethane products.

2.2 How SA-102 works

SA-102 is a highly efficient thermally sensitive catalyst whose main component is an organic tin compound. During the polyurethane reaction, SA-102 can maintain low catalytic activity at lower temperatures, thereby extending the reaction time and ensuring uniform reaction. When the temperature rises to a certain range, the catalytic activity of SA-102 is rapidly enhanced, accelerating the reaction process and shortening the curing time.

This temperature sensitive catalytic characteristic makes SA-102 have a significant advantage in the production of outdoor polyurethane products. For example, in high temperature environments in summer, SA-102 can quickly catalyze reactions and shorten production cycles; in low temperature environments in winter, SA-102 can maintain low catalytic activity, ensure uniform reactions and avoid product defects caused by excessive reactions.
