Introduction

With the increasing awareness of environmental protection and the increasingly strict regulations, environmentally friendly coatings are becoming more and more widely used in the fields of construction, automobiles, furniture, etc. Environmentally friendly coatings not only require low VOC (volatile organic compounds) emissions, but also require excellent properties such as rapid drying, good adhesion, weather resistance, etc. Among these properties, rapid drying and excellent adhesion are key indicators in coating formulations. Jeffcat TAP amine catalysts, as a highly efficient catalyst, play an important role in environmentally friendly coating formulations. This article will discuss in detail the mechanism of action, product parameters and its application in environmentally friendly coatings.

1. Overview of Jeffcat TAP amine catalysts

1.1 What is Jeffcat TAP amine catalyst?

Jeffcat TAP amine catalyst is a highly efficient catalyst specially used in polyurethane coatings and adhesives. It significantly shortens the drying time of the coating while increasing the adhesion of the coating film by accelerating the reaction between isocyanate and polyol. Jeffcat TAP amine catalysts have the characteristics of low odor and low VOC emissions, and meet the requirements of environmentally friendly coatings.

1.2 The main components of Jeffcat TAP amine catalysts

Jeffcat The main components of TAP amine catalysts are triethylamine (TEA) and dimethylaminopropylamine (DMAPA). These two components have a synergistic effect in catalytic reactions, which can effectively increase the reaction rate while maintaining the physical properties of the coating film.

2. The mechanism of action of Jeffcat TAP amine catalyst

2.1 Catalytic reaction mechanism

Jeffcat TAP amine catalysts accelerate the reaction of isocyanate with polyols through the following mechanism:

1. Activated isocyanate: The amine group in the catalyst reacts with the isocyanate to form an active intermediate and reduce the reaction activation energy.
2. Promote the polyol reaction: The active intermediate reacts with the polyol to form polyurethane chains, and at the same time releases the catalyst and continues to participate in the subsequent reaction.

2.2 The mechanism of rapid drying

Jeffcat TAP amine catalysts significantly shorten the drying time of the coating by accelerating the reaction rate. Specifically manifested as:

• Short drying time: The catalyst quickly forms a dry film on the surface of the coating to prevent dust and impurities from adhering to.
• Short the working time: The catalyst accelerates the internal reaction, so that the coating reaches a completely dry state in a short time.

2.3 Mechanism of excellent adhesion

Jeffcat TAP amine catalysts improve adhesion of coating films by:

• Enhanced Interface Binding: The catalyst promotes the reaction between the isocyanate and the substrate surface to form stronger chemical bonds.
• Improve the density of the coating film: The catalyst makes the internal structure of the coating film denser, reduces pores, and enhances adhesion.
