UV CURABLE ABRASION-RESISTANT COATING ADDITIVE AB02®

The product AB02®can improve abrasion resistant highly which, when applied to the UV curable coating and cured, form transparent coatings having superior abrasion resistant properties. It's inorganic compound powder and the main contain is high transparent alpha phase alumina. In Taber Test the abrasion data is from the 0.18g reduce to 0.08g. In Stainless Steel Wool Test, after scratch the coat, it still clean (no turn black), and difficult to find the haze. When applied to the coating, the coating can still maintain high glossily surface, good fluid, difficult sedimentation. The coating can be applied to wood, paper, glass, plastic, leather,etc. substrate by conventional methods, such as spray coating, curtain coating, roll coating, etc. to form a continuous surface film. The price is competitive, less than the price of UV coating.


The main features:
Chemical ingredient:   alpha phase Al2O3
Hardness:                    7-8 Moths
Average particle size:   2-3 micron
Refractive index:         1.53
Loosed bulk density:   0.5g/cm3
True specific gravity:   2.5-2.6g/cm3
Ph:                   7
Oil absorption (TPGDA): 35ml/100g
Whiteness:              93%

Example
UV curable coating     85g
AB02®                       15g
Mixture, and high speed (1200RPM) stirred, through 300 Mesh filter, test the particle size.

Super abrasion resistant coatings additives  SAR-30, SAR-40, SAR-50

The products are made of highly hard alumina, the particle size is 30 micron and 40 micron, it's the same with the Treffert UV coatings filler. They are SAR-30 and SAR-40, and they are all used into UV curable bottom coatings. When SAR-30 used into bottom coatings the taber test can be to 0.06gram/100 circles(500g load), and the coatings film is weared out after 800 circles. The SAR-40 taber test data is 0.03gram/100circles 500g load) and 1100circles wear out.

 The top varnish is high scratch resistant and the bottom coatings is high abrasion resistant, so the parquet can be very good.
