1. Introduction

In modern industrial production, rapid curing systems are widely used in coatings, adhesives, composite materials and other fields due to their high efficiency and energy saving characteristics. However, in practical applications, fast curing systems often face problems such as excessive curing speed, short operating time, and uneven curing. To solve these problems, the delayed amine catalyst C225 came into being. This article will introduce in detail the product parameters of the delayed amine catalyst C225, its application in a rapid curing system and its performance, helping readers to fully understand the characteristics and advantages of this catalyst.
