MRX Screen Ink (Isophorone free Two-Pack Ink for Hard Coated Surfaces)
MRX is an environment and human friendly screen ink that is free of benzene, toluene, xylene, and isophorone. Designed as a 2 pack ink for hard coated plastic surfaces, it is widely used for cover plates of cellular phones and handheld game consoles. Superior adhesion to hard-coated surfaces and good post-forming properties.
Substrate
♦ Hard coated plastics on cellular phones, audiovisuals and handheld game consoles
♦ Hard coated Acrylic and PC
♦ Hard coated Acrylic and PC
Special Features
♦ Environment and human friendly screen ink as it is free of benzene, toluene, xylene, and isophorone
♦ Superior adhesion to hard-coated plastics
♦ Suitable for post-forming applications such as cutting

Thinning, Stirring, Cleaning
♦ Stir well before every use.
♦ Z-004 (extra retarder) thinner is recommended for standard applications with 15-20% dilution.
G-001 (fast dry), G-002 (normal), G-003 (slow dry) thinners are also available.
♦ Avoid excessive thinning and avoid using other solvents as this may affect adhesion, curing, etc.
♦Screen Cleaner N is recommended to clean the stencil.

Catalyst Mixing
♦ 210 Catalyst is recommended for standard use.
♦ Add Isocyanate catalyst and mix well before use. Add 210 Catalyst 5 weight parts (6 weight parts for 000 Medium) to 100 parts of the ink and stir well. Pot life is 8 hours.
♦ 106 Catalyst is recommended for faster curing. Add 106 Catalyst 10 weight parts (11 weight parts for 000 Medium) to 100 parts of the ink and stir well. Pot life is 3 hours.
♦ Gelatinization may occur when pot-life expires. Please prepare required quantity only.

Printing
♦ T180-T300 mesh monofilament screen is recommended as stencil.
♦ Coverage is 30-50 m2/kg at 250 mesh.
♦ Coverage is 30-50 m2/kg at 250 mesh.
Drying
♦ Drying time is about 20-30 minutes at room temperature or 30 minutes at 80°C.
♦ Drying and adhesion of ink is affected by 1) drying temperature, 2) drying time, 3) grade and type of the substrate, and 4) treatment degree of substrate
♦ Heated air dry is required as insufficient drying may cause blocking. Start piling up only after confirming resistance of ink layer.

Additives:
♦ SM-40 Defoamer: 1-2% improves leveling, avoids foaming and repelling
♦ Thixotropic agent: 1-2% increases viscosity
