Polyacrylate coating glue

Polyacrylic ester fabric coating adhesive is currently one of the commonly used coating adhesive, it has the following advantages:

1. Resistant to sunlight and weather fastness is good, not easy yellowing;

2. Good transparency and inclusive, conducive to the production of colored coating products;

3. Good washing resistance;

4. Strong adhesion;

5. Low cost.

Its defect is:

1. The elastic is poor, easy to crease;

2. Surface finish is poor;

3. The handle is moderately difficult to adjust.

First class polyacrylate coating adhesive are simple waterproof type products, through decades of development, the current variety not only has waterproof and moisture permeable, flame retardant and other functions, but also the characteristics of energy saving at low temperature. Polyacrylate typically are the hard coating rubber components (such as polyacrylic acid methyl ester, etc.) and soft components (such as poly (butyl acrylate) copolymer. Polyacrylate coating of main monomer acrylic acid, methyl acrylate, ethyl acrylate, butyl acrylate, etc., in order to improve its waterproof performance, can add acrylamide and acrylonitrile when necessary, polymerization initiator usually use peroxide (such as potassium persulfate, etc.).

Polyurethane coating adhesive

Polyurethane coating agent is the development of the main types, its advantage lies in:

1. Soft and elastic coating;

2. The coating strength is good, can be used for very thin coating;

3. The coat is porous, with moisture and ventilation performance;

4. Wear resistance, resistance to wet and dry cleaning.

Its defect is:

1. The high cost;

2. The climate resistance is poor;

3. The water, heat, alkali hydrolysis.

Of PU coating agent according to the classification: polyester polyurethane; Department of polyether polyurethane; Aromatic isocyanate is polyurethane; Aliphatic isocyanate polyurethane. By using the medium into solvent and water system.

PA painted white and PU coated white or with PA and PU cellophane tape from his appearance is very difficult to distinguish, but PA and PU or is there a difference, one is: feel PA handle is acerbity PU more smooth, the flexibility of the PU is better than PA; One is luster: PA without burnish, PU luster is bright; Then a PU has a very good film, feel the feeling of skin membrane. In short, the PU is bright, good elasticity, a sense of membrane, and PA will not meet the conditions. Alone, of course, these general novice or it is difficult to distinguish, by the way, teach you a small doohickey: 1, with rubber by firm pressure on the cloth and then to PA will follow up rubber adhesive and PU is sticking up. 2, 2 cloth coating on the surface of every drop a few drops of toluene (e.g., conditional word), and then gently with the hand rub (pay attention to protect, hand don't direct contact with toluene), PA coating will drop, PU won't fall. To PA and PU, mainly according to the requirements of the required fabric coating. PA coating, also called AC adhesive coating, acrylic coating, is by far the most common one of the most common coating, coating can increase the handle, windproof, have hang down feeling.
