Bogao Waterborne PU Curing Agent BG-2655-80

In recent years, with the guidance of environmental protection policies and the promotion of many coating manufacturers, waterborne paint has been increasingly recognized by the market, and the performance of two-component waterborne paint has been comparable to that of oil-based paint in many aspects, which is inseparable from the development and application of waterborne PU curing agent.

Bogao’s waterborne PU curing agent BG-2655-80, for waterborne coatings, waterborne adhesives, waterborne inks, etc.

It is used as curing agent components for waterborne two-component PU system.

It has the characteristics of Paint film fast drying, excellent physical and chemical properties.

Waterborne PU curing agent

Waterborne PU curing agent contains a large number of isocyanate groups (- NCO), which can be condensed with many functional groups such as hydroxyl, amino and carboxyl groups. How to effectively control the side reaction and prepare the two-component waterborne paint with excellent performance requires selecting the appropriate waterborne curing agent, and mastering the key points of formulation design and film preparation in detail.

The application research of waterborne PU curing agent began at the end of the 1980s. Bayer has been in the forefront of research and development, and has also contributed to the promotion of waterborne curing agent and waterborne paint. It started late in China, but has developed rapidly, and is widely used in industrial coatings, floor coatings, wood coatings, automotive industry, textile industry and other fields.

  • Application in industrial coatings

Waterborne PU curing agent is matched with water-borne hydroxyl dispersion resin. Because the hydroxyl dispersion has small molecular weight, high hydroxyl value and no surfactant, it has high density, high hardness, good gloss and good resistance after crosslinking and curing. It can be completely comparable to oil-based coatings in performance, and can be widely used in industrial anti-corrosion and decorative coatings.

  • Application in floor coating

Two-component waterborne PU coating is used for the water-based floor, which has the characteristics of environmental protection and health. The waterborne PU coating has the characteristics of high flexibility, wear resistance, weather resistance, water resistance and good scratch resistance.

  • Application in Wood Coatings

High-quality waterborne matte wood paint is a direction of the furniture industry. The paint film gives a good texture feeling after extinction, and is very popular with people. The varnish coating added with matting agent has low transparency and poor resistance to medium. The matting effect can be achieved through the curing agent from the molecular structure. The same kind of water paint, with different structure of matte curing agent, can obtain the gloss we need.
