Product Introduction
Product Performance
The sulfonic acid curing agent for casting resins is a liquid curing agent produced by sulfuric acid sulfonation and subsequent separation of benzene, toluene, and xylene. This product appears as a brownish-red or brownish-transparent liquid, free from any visible insoluble particles. It should remain completely clear without crystallization even at temperatures above -15°C.
Product Applications
The sulfonic acid curing agent for casting resins is widely used to cure and shape various types of resins, such as furan and phenolic resins, under diverse temperature and humidity conditions. This product boasts rapid curing speed, a straightforward molding process, and excellent sand disintegration properties, making it ideal for meeting the demands of a wide range of molding techniques.
