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.
