How to choose anti-mildew agent for epoxy floor paint?

1. The anti-mildew agent will not chemically react with the components of epoxy floor paint: resin, pigment, filler, additives, curing agent, etc. and lose the role of inhibiting mildew.
2. Test whether it will affect the color and adhesion of epoxy floor paint film after adding.
3. can be uniformly dispersed in the paint, so that all parts of the coating has a long time effective inhibition of the growth of mold role.
4. The use of non-toxic mold agent, to ensure that the floor coating film Hou harmless to humans.

 

 

 

 

 

 

 

 

 

 

 

Slip and anti-scratch agents are additives for the purpose of improving the smoothness of the coating film. They are a kind of “coating film surface condition adjustment aids”. They are widely used in household appliance coatings, automotive coatings, furniture coatings, plywood coatings, Pre-coated coil coatings and can coatings are also suitable for water-based coatings.

In coatings, the necessity of using slip and anti-scratch agents can be roughly divided into two aspects. 1. Protect the coating film from scratches, called scratch resistance

Products with high decorative requirements such as household appliances, automobiles, and furniture must go through the assembly process in the continuous production process. Even if the process is very careful, it will inevitably cause slight scratches on the coating film due to physical contact. These paraffin wax emulsion data sheet products are inevitably scratched by contact with objects during use, or dust on the surface of the coating film caused by static electricity, and small scratches on the coating film will also occur when wiped with a cloth or feather broom. Such slight scratches not only affect the appearance of the paint film, but also cause damage to the paint film due to moisture intrusion. Therefore, scratches and abrasions should be avoided as much as possible, or the damage degree of scratches and abrasions should be reduced to a minimum, it is necessary to make the surface of the coating film slippery.

The so-called scratch resistance is a kind of resistance of the coating film to mechanical damage, and the coating film with slippage also has scratch resistance. Compared with the baking type coating film, the air-drying coating film has poor resistance to hard objects and trauma, especially for coatings that require good film flexibility and plump appearance. No slip agent is added to achieve scratch resistance. The requirements are more difficult.
Improve the workability of continuous industrial coating, that is, anti-blocking

In the continuous coating process of coils, plywoods, metal parts, etc., especially when coating blades and plate-shaped parts, the spreading and storage is limited by the site, and it is often necessary to have the coating film not fully cured or have not cooled down after baking. It is stacked and stored at room temperature, so that there may be adhesion and adhesion between the coating film or between the coating film and the back of the coated object (called pressure adhesion and thermal adhesion), and it is also easy to cause damage. This situation often occurs in some thermoplastic volatile coatings and latex paints when metal pre-coated coils are painted, and the coating film also has the disadvantages of pressure adhesion and hot adhesion. Generally speaking, the smoother the coating, the less sticky it is. Adding slip agents can avoid or reduce adhesion and damage to varying degrees.
