PP surface treated water 
 Instructions for use 
 Outline 

 Our company introduced the latest research results of the U.S. chemical industry, Dr. EASTMAN (EASTMAN) raw materials, fine synthesis powerful series of PP coating with excellent adhesion agent. Widely used in paints, screen printing, coating, printing and other industries, can greatly improve the adhesion of inks, paints and other coatings of PP, class plastic workpiece. 

 Product physical properties

 Flash Point: about 12 ℃ 

 Appearance: light yellow transparent liquid Colorless transparent liquid 

 Taste: with the ordinary days that water taste 

 Technical indicators 
 A, the adhesion level (detected after matching finish using the program grid, with 3M adhesive tape method) ≥ 1d, B, temperature variability (detected after matching finish ie 8h/RT4h -30 ℃, 80 ℃ 8h / RT4h, 8 cycles) does not blister, do not fall off. C, water-resistant day (40 ℃, deionized water) ≥ 3. Hardness (using the pencil method) ≥ HB 
 Feature 
 Strong adhesion, easy construction, short dry time, and can enhance the coating water resistance, oil resistance and hardness. 

 Use 
 Pre-construction divisible from film and dust of the workpiece surface. 

 (2) PP water sprayed on the workpiece surface; workpiece can also be dipping PP water. 

 PP workpiece surface coated with 6-8mm (film thickness after the hard work) thick PP water, dry 5 minutes, and then cast a matching finish. 

 Sprayed finish leveling 10 minutes, and then 70 ° C to accelerate the curing of 30 minutes, room temperature curing 24 hours packing.
