Fast drying characteristics of low-odor foam gel balance catalyst in environmentally friendly coatings
Introduction
With the increase in environmental awareness, environmentally friendly coatings are becoming more and more widely used in the fields of construction, furniture, automobiles, 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. As a new environmentally friendly additive, the low-odor foam gel balance catalyst exhibits significant rapid drying characteristics in environmentally friendly coatings. This article will introduce in detail the characteristics, mechanism of action, product parameters and its application in environmentally friendly coatings.
1. Overview of low-odor foam gel balance catalyst
1.1 Definition and Features
Low odor foam gel balance catalyst is an additive specifically used in environmentally friendly coatings. Its main function is to accelerate the drying process of the coating while maintaining low odor and low VOC emissions. This catalyst promotes rapid curing and film formation of the coating by adjusting the chemical reaction in the coating, thereby improving the construction efficiency and performance of the coating.
1.2 Mechanism of action
The mechanism of action of low-odor foaming gel balance catalyst mainly includes the following aspects:
- Promote crosslinking reaction: The catalyst can accelerate the crosslinking reaction between the resin in the coating and the curing agent, forming a dense mesh structure, thereby improving the hardness and wear resistance of the coating.
- Adjust gel time: By adjusting the amount of catalyst, the gel time of the coating can be controlled to maintain appropriate fluidity during construction and cure quickly after construction.
- Reduce VOC emissions: The catalyst itself has low odor and low VOC characteristics, which can effectively reduce the impact of coatings on the environment during use.
