Epoxy Screen Printing Inks: New Applications

Epoxy silk screen ink ink layer evenly bright, pigment dispersion, fine uniformity, over the net, leveling well, after curing the polar substrate has excellent adhesion, the coating has a higher hardness, gloss and Good water resistance, weather resistance, chemical resistance. According to experts from the China Epoxy Resin Industry Association, it is currently becoming a new hot spot for epoxy resin applications. The scope of this product includes: a variety of metals, glass, ceramics, wood, melamine products, UPE products, cross-linked PU products, and surface treated PE, PP products, and vacuum electricity (steam) plating products, their conventional The main performances are: Viscosity: 5000-15000CPS (depending on temperature and color), Adhesion: 5B excellent, Drying conditions (used with KT-000 curing agent as an example): Complete curing at 120-130°C for 20 minutes (full Dry), completely cured at 80-90°C for 2 hours, temperature 25°C/humidity 75°C, 1 day hard dry for 4 days, dry, over-net performance: 77T～165T mesh yarn? (except gold, silver and pearl powder formulated ink).

It is reported that when the product is used, the diluent is KT-specific thinner, and the defoamer is KT-specific defoamer. The coating area is 10-20m2/kg (The coating area is tested with 120T polyester monofilament emulsion, screen plate. As a standard), the curing agent is KT-000 which is a glass curing agent and EP-002 is a metal curing agent. Experts recommended by the China Epoxy Resin Industry Association are: When using KT series inks, they should be used in conjunction with KT series curing agents, and the ratio (main agent: curing agent) should be 100:20; it should be established with KT curing agent before use. Mix well for 10 minutes; Add 10 to 30% thinner as needed to dilute; contaminated material should be cleaned or wiped with a stained oil on the surface for good printing results; when printing errors should not be completely dry before use The word water is removed and reprinted; in the printing process, the screen plate is blocked, and then washed with wash water; then the color must be printed before the color is dry or hard dry; adhesion, hardness, and acid resistance Properties, oil resistance, stain resistance, oil resistance, scratch resistance, abrasion resistance, etc. Performance testing is required only after the ink layer is completely cured; KT series inks must not be mixed and matched with other types of ink without permission.

Experts from the China Epoxy Resin Industry Association said that it is important to add enough diluent before use to stir well; different types of ink use special thinners; try printing and confirm that the requirements are met before mass production; do the surface of the printed material Remove grease and impurities to promote adhesion; screen or printed surface with static electricity, will cause the printing ink will have pinholes; high humidity will affect the printing effect; after the coating is dried, can Stacked shipment; after the completion of the operation, the remaining ink tightly seals the container; when the printing quality is unfavorable, consult the technical department of the company and do not handle it on its own; use will not be compensated if it is used improperly. Special attention should be paid to the safety rules: Ink, thinner, and smoking are strictly prohibited during use and storage. When using, pay attention to the good ventilation of the construction site. Try to avoid direct contact with the skin. Inadvertently splash water into the mouth, nose, eyes, and ears. Directly to the doctor, allergies should be coated with a layer of skin care cream or impermeable gloves before use.
