Introduction

With the increasing awareness of environmental protection and the increasingly strict regulations, low-volatile organic compound (VOC) materials are increasingly widely used in the construction, automobile, electronics and other industries. As an indispensable material in construction and industry, waterproof sealants have also received widespread attention in their environmental protection performance. As a new environmentally friendly catalyst, the application of low-odor catalyst in waterproof sealants provides new possibilities for low VOC solutions. This article will introduce in detail the characteristics, application advantages, product parameters and their specific applications in waterproof sealants.

1. Overview of low-odor catalyst ZR-40

1.1 What is low-odor catalyst ZR-40?

The low odor catalyst ZR-40 is an environmentally friendly catalyst specially designed to reduce VOC emissions. It reduces the generation of harmful gases by optimizing chemical reaction paths, thereby significantly reducing the odor and VOC emissions of the product during use. ZR-40 not only has efficient catalytic properties, but also can work stably in a variety of polymer systems, and is suitable for the production of a variety of sealants and adhesives.

1.2 Main features of ZR-40

• Low VOC emissions: ZR-40 produces almost no harmful gases during the reaction process and meets strict environmental protection standards.
• Low Odor: Sealant produced using ZR-40 has almost no irritating odor during use, improving the construction environment.
• High-efficiency Catalysis: ZR-40 has efficient catalytic activity, can accelerate polymerization and shorten production cycles.
• Good stability: ZR-40 shows good stability in various polymer systems and is not prone to side reactions.
• Environmental Safety: ZR-40 does not contain heavy metals and other harmful substances, and is harmless to the human body and the environment.

2. Advantages of ZR-40 in waterproof sealant

2.1 Reduce VOC emissions

Traditional waterproof sealants release a large amount of VOC during production and use. These harmful gases not only cause pollution to the environment, but may also cause harm to human health. By optimizing the catalytic reaction path, ZR-40 significantly reduces the generation of VOCs, making the waterproof sealant more environmentally friendly.

2.2 Improve the construction environment

Due to the low odor properties of ZR-40, the waterproof sealant produced by it is almost in the process of construction using almost any waterproof sealant.No irritating odor, greatly improving the construction environment and improving workers' comfort and work efficiency.
