What is polyurethane binder?

Polyurethane binder refers to an adhesive containing urethane groups (-NHCOO-) or isocyanate groups (-NCO) in the molecular chain. Polyurethane adhesives are divided into two categories: polyisocyanate and polyurethane. Polyisocyanate molecular chain contains isocyano group (-NCO) and urethane group (-NH-COO-), so polyurethane adhesive shows a high degree of activity and polarity. It has excellent chemical adhesion with substrates containing active hydrogen, such as foam, plastic, wood, leather, fabric, paper, ceramics and other porous materials, as well as metals, glass, rubber, plastics and other materials with smooth surfaces.

Introduction to the principle of Polyurethane Binder

Polyurethane Binder is a glue containing urethane groups and isocyanate groups in the molecular chain. Due to the strong polar isocyanate and urethane groups, it has high reactivity, can be cured at room temperature, and has excellent adhesion to various materials. performance. Through modification, the heat-resistant group was introduced into the hard segment of the polyurethane, and a one-component polyurethane adhesive with a heat resistance of nearly 120 °C was produced, and it had good adhesion performance at a high temperature of 150 °C, which expanded the application of the polyurethane adhesive. scope.

Introduction to the classification of Green Valley Polyurethane Binder

Green Valley Polyurethane Binder is divided into room temperature glue and high temperature glue. Room temperature glue can bond with most solid materials including EPDM particles, and is used for the laying of plastic tracks, kindergartens, stadiums, fitness paths and other plastic venues. High temperature glue needs to be cured on heating equipment, mainly used for rubber floor tiles, rubber coils and other high temperature molding bonding materials.

Introduction to the advantages of polyurethane binder

The diversity of polyurethane binder has prepared solutions for many bonding problems, and is especially suitable for places where other types of adhesives cannot be bonded or where bonding is difficult. In addition, polyurethane binder also have the characteristics of adjustable toughness, simple bonding process, excellent low temperature resistance and excellent stability. It is precisely because of the excellent adhesion properties and adaptability of polyurethane binder to a variety of substrates that its application fields continue to expand.

The main advantages are as follows:
(1) Good water resistance and medium resistance.
(2) High bonding strength and high initial adhesion.
(3) Good storage stability.
(4) Resistance to freezing and thawing, and high temperature resistance.
(5) Fast drying speed and good film-forming properties at low ambient temperature.
(6) Good construction technology.

Polyurethane Binder material introduction

Green Valley Polyurethane Binder is mainly composed of polyether polyol and diphenylmethane diisocyanate and other base materials mixed and reacted. The raw materials and auxiliary materials used are of high quality. The finished product does not contain TDI, toluene, xylene, short-chain chlorinated paraffin, DOP, Hazardous products such as MOCA can reach the level of colorless and odorless. The viscosity and thin consistency are just right for the construction, and the curing time can be adjusted according to the actual ambient temperature. In order to solve the yellowing phenomenon caused by the adhesive itself, materials such as anti-ultraviolet agent and anti-aging agent are added to delay the color change, and the environmental protection index can reach the national standard.

Our requirement is to meet the standards of the new national standard. The requirements for thickness, elasticity, tensile strength, etc. are relatively strict. The seller answered me one by one. The materials are also environmentally friendly, and I am very relieved. I am very satisfied with choosing their home and look forward to the next cooperation.
