Coating slip agent

Brief description:

       Coating slip agent is to improve the performance of the film for the purpose of smoothing additive, it is a film surface conditioning agent, widely used in household appliances paint, automobile paint, furniture paint, paint adhesive sheet, pre-coated sheet coatings and can coatings and so on.

Role:

In the paint, the necessity of slip agent used in the following two aspects:

1. The protection film to avoid scratching

Household appliances, automobiles, furniture and other decorative articles requiring high performance in continuous production process, to go through the assembly process, the process is even great attention to physical contact is inevitable due to the coating produced a slight scratch. These articles during use, static electricity generated by the film surface adhesion of dust, wipe with a cloth, the film will also have minor scratches when feather broom sweep. Such minor scratches not only affects the appearance of the film, and water intrusion can lead to the destruction of the coating. So as much as possible to avoid scratches, it is necessary to make the surface of the coating slip.

The so-called anti-scratch coating is a kind of resistance to mechanical damage, with a slip of the film also has scratch resistance. Since the dry film coating and baking compared to less resistance to a hard object and trauma, especially in the coating requires good flexibility, appearance and fullness of the occasion, do not add up to a slip agent To scratch requirement is more difficult.

2. Improve continuous chemical coating workability

Sheet, adhesive sheet, construction carpentry and other continuous coating works, especially the blades, when the plate-like member coating, roll storage subject to site constraints, often required at the time of the film is not completely cured on bulk storage, so Tu there may be between a film or coating and is coated on the back of adhesions and adhesion (known as blocking phenomenon) is also prone to scratches. This situation has occurred in the paint often pre-coated metal sheet. Slip agent can be added in varying degrees to avoid or reduce adhesion and abrasion.

Application mechanism:

Coating slip agent added and after curing the coating, the slip agent can float on the surface of the film (the best condition can all be attached to the film surface), reducing the surface tension of the coating, the coating having a very low surface resistance, thereby reducing the coating on the second surface coefficient of friction, reducing surface friction, resist scratches and smudge protection.

Species:

Coatings for plastics slip agent and slip agent in substantially the same breed. In the wider application of the coating, the better the slip agent excellent in 3 categories.

1. aliphatic hydrocarbons

This class of liquid paraffin, vaseline, synthetic paraffin, polyethylene wax, and polypropylene wax. With the development of petrochemical industry, polyethylene wax and polypropylene wax used more and more.

2. fatty acid amides

Do slip agent used preferably fatty acid amides of unsaturated fatty acid amide, oleic acid amide.

3. silanes

Do slip agent used silanes are the following polydimethyl siloxanes, phenyl methyl siloxanes, polyether-modified polydimethylsiloxane, polyester-modified polydimethylsiloxane, etc. .
