YS-M8100 Metal vacuum coating UV primer

Word:[Big][Middle][Small] 2020/10/28     Viewed:    



Product name: UV metal vacuum coating finish
Product No.: YS-M8100
Main composition: The main component is acrylic resin with excellent performance, mixed with acrylic monomer, high-performance pigments and fillers, additives and photoinitiators.
Scope of application: topcoat for vacuum ion evaporation coating, sputtering coating, and magnetron coating.

Production Specification:  
Product performance:
◆Standard product of UV metal vacuum coating topcoat, fast curing speed. 
◆Reasonable viscosity, suitable for spraying process, convenient and quick construction.
◆The paint film has good hiding power, strong fullness, good leveling, and good color solubility.
◆Good adhesion with aluminum plating and low shrinkage.
◆The paint film has good hardness and is not easy to be polished, suitable for heavier workpiece surfaces.

Performance Evaluation:
◆Viscosity: Paint No. 2 Cup (Iwata Cup) 8-9s , 25℃
◆Curing speed: 6 lights 1 time, 60m/min
◆Hardness: 2H-3H
◆Adhesion: ≤2 level

Method Application:
◆Oil mixing ratio: It can be used directly under normal circumstances, and can be diluted with butyl acetate when necessary.
◆Spray construction, coating amount (wet film) 120-150g/m2, wet film thickness 15-25um.
◆Place the heating leveling line for 4~5 minutes/UV light curing (>500mJ/cm2)

Recommended process:

Substrate sanding and dust removal→substrate degreasing and degreasing→substrate loading fixture→up production line→electrostatic dust removal→automatic spraying of the primer→infrared leveling→UV lamp curing→off-line cage→into the coating machine coating→up Production line → production line → automatic spraying of this product → infrared leveling → UV light curing → offline → lower fixture → packaging



Normal Question&Aanalysis:  
◆Poor adhesion: the paint film is not completely dry; there are many thinner residues; the substrate is not treated well; the paint film is too thick; the polishing is not in place, and the adhesion between the paint film layers decreases.
◆Sickness of paint film such as crater on the surface: the paint is contaminated; the coating amount is too low; the substrate is not fully wetted.
◆Poor leveling: the proportion of diluent is not appropriate; the temperature of the leveling line is not enough; the heating leveling time is too short, and the leveling is insufficient. Precautions:  
◆This product is a transparent viscous liquid. Slight turbidity is normal, and it needs to be filtered again before use.
◆If you need to reduce the viscosity of this product before spraying, you can add butyl acetate and stir evenly.
◆Construction by spraying method. After construction, add infrared leveling line for 4 to 5 minutes, and then light curing.
◆Keep the temperature of the leveling line to ensure that the workpiece stays for enough time.
◆It is not advisable to paint too thick at one time, which will affect the adhesion and cause sagging.
◆The substrate must be polished beforehand, and the surface must be cleaned of oil and dust, otherwise the adhesion will be affected.
◆Reconstruction on the fully cured paint film, the paint must be polished and dust removed again.
◆The construction environment of this product must avoid direct sunlight or strong light sources.

Packing & Storage:
◆Standard packaging:  18kgs, 50kgs, 190kgs.
◆This product should be stored in a dry and low temperature place, kept clean and ventilated, and sealed in time after use.
◆The shelf life of this product is valid within half a year from the date of production.

Safety Rule:
◆This product has low toxicity, avoid contact with skin and eyes.
◆If this product gets on your skin or clothes, wipe it off with a cloth first, and then wash it with water to prevent skin burns. If it gets into your eyes, rinse immediately with water for more than 20 minutes.
