The recommended use level is based on experimental, field evaluations and it should only be used as a reference for practical applications. The actual amount to be used is determined by the formulation: the composition of the formulation, the substrate to be applied and the environment in which the coating is to be applied, all have an influence on the amount to be used.

The following recommended usage amounts are expressed as % of the final product
Paints, coatings, cement coatings 0.01-0.025%
Polymer dispersions 0.01-0.025%
Ink 0.01-0.025%
Fountain solution (in use) 0.025%
Adhesives and sealants 0.01-0.025%

 

 

 

 

 

 

 

 

 

 

 

 

Versatility and economy
What this refers to is how to expand the scope of application or reduce the cost through the selection of additives for the same formula, rather than simply adding additives to increase the cost to improve performance. One of the most classic examples is the addition of adhesion promoters (such as Deqian Ad he rant ADP) to general baking paints, especially alkyd amino baking paints. Since general amino baking paints are suitable for some non-ferrous metal substrates (such as aluminum , Aluminum alloy, galvanized, stainless steel, etc.) has poor adhesion. If a special resin is selected, it will greatly increase the cost and increase the inventory variety. Add the adhesion promoter Adhe rant ADP at a dosage of about 2%. Excellent adhesion has little effect on cost, paint and film performance, so as to achieve the result of improving versatility and economy. Other functions such as wax powder, wax slurry and modified polysiloxane for slipping, anti-scratch, abrasion resistance and special hand feeling are also a way to improve the economic efficiency with a small amount of addition, otherwise it will only rely on resin Or it is difficult for the curing agent to achieve very good smoothness, scratch resistance, and abrasion resistance. The increased cost is higher than adding a small amount of these additives, and in many cases it cannot be synthesized. This is the coating additives. Excellence and necessity.

Precautions for additives in the application process
In the field of solvent-based coatings, it is often encountered that after engineers describe requirements or problems, suppliers recommend corresponding additives and solutions. After specific tests and evaluations, the problems cannot be solved, or other problems arise. The reasons and factors are quite complicated. Because the chemical structure of solvent-based coatings from resins/curing agents, solvents, pigments, fillers to additives is very different, and the interaction between the four components leads to complex interactions.
