Leather Grade

 

The new generation of exclusive leather delustrant——Suitable for solvent-based or water-based leather surface coating agent

 

Product features:

 

High transparency

 

Strictly control particle size distribution of product, and give better transparency for leather coating.

 

Excellent dispersibility   Easy to add

 

The delustrant can easily disperse in both polar solvent and aqueous solution. A delustering effect may

reached by just using normal dispersion machine to disperse in high speed for 15-30 minutes.

 

High delustering efficiency

 

Additive amount of delustrant is generally between 3% to 10%, and the typical additive amount is 5%.

 

Stable chemical property 

 

As the delustrant is with high purity and low impurity, its chemical property is very stable.
