Mercaptan Based Epoxy Hardener: The Key to Strong and Durable Epoxy Resins

Epoxy resins are widely used in various industries due to their excellent adhesion, chemical resistance, and mechanical properties. However, to achieve the desired performance, epoxy resins need to be cured with the appropriate hardener. Among the various types of epoxy hardeners available, mercaptan-based hardeners are known for their unique properties that make them ideal for demanding applications. In this article, we will explore the features and benefits of mercaptan-based epoxy hardeners, with a focus on INNO Specialty Chemicals' GABEPRO GPM-888 GPM800.

Overview of Mercaptan-Based Epoxy Hardeners

Mercaptan-based epoxy hardeners are a type of thiol-amine curing agent that reacts with epoxy resins to form a cross-linked network. Unlike other types of hardeners that rely on amine or anhydride chemistry, mercaptan-based hardeners use the thiol group (-SH) to initiate the curing reaction. This unique chemistry provides several advantages, such as:

- Low viscosity: Mercaptan-based hardeners are typically low in viscosity, which means they can be easily mixed with epoxy resins without adding significant thickness to the final product. This is particularly useful for coatings and adhesives applications where a thin film is desired.n- Excellent adhesion: Mercaptan-based hardeners have good wetting properties, which means they can penetrate into the substrate and bond strongly with it. This makes them ideal for applications where adhesion is critical, such as in aerospace, automotive, and marine industries.n- High flexibility: Mercaptan-based hardeners can provide a high degree of flexibility to the cured epoxy, which is useful in applications where the substrate is subject to thermal or mechanical stresses. This can help prevent cracking or delamination of the epoxy coating or adhesive.n- Moisture resistance: Mercaptan-based hardeners are less sensitive to moisture than other types of hardeners, which can be an advantage in humid or wet environments.
