Delayed low odor amine catalyst LED-204: Achieving efficient and low VOC emissions polyurethane solutions

Introduction

Polyurethane materials have become one of the indispensable materials in modern industry due to their excellent physical properties and wide application fields. However, traditional polyurethane production is often accompanied by emissions of highly volatile organic compounds (VOCs), which not only pollutes the environment, but also can have adverse effects on the health of operators. To solve this problem, the delayed low-odor amine catalyst LED-204 came into being. This article will introduce the product characteristics, application fields, technical parameters and their advantages in polyurethane production in detail.

1. Product characteristics of LED-204

1.1 Low odor and low VOC emissions

LED-204 is an amine catalyst specially designed for polyurethane production. Its major feature is its low odor and low VOC emissions. Traditional amine catalysts release irritating odors during the reaction process, while LED-204 significantly reduces the generation of odors by optimizing the molecular structure and reducing VOC emissions, which meets modern environmental protection requirements.

LED-204 has a delayed catalytic effect, which means it does not work immediately at the beginning of the polyurethane reaction, but starts to accelerate the reaction only after a certain period of time. This characteristic makes polyurethane materials have better flowability during the production process, facilitate the filling of complex molds, and reduce the generation of bubbles and defects.

1.3 High-efficiency catalytic performance

Although LED-204 has a delayed catalytic effect, its catalytic efficiency is not inferior to that of traditional catalysts. Under appropriate temperature and time conditions, LED-204 can significantly accelerate the reaction speed of polyurethane, shorten the production cycle, and improve production efficiency.

1.4 Wide applicability
