JELCON RAYTACK-10N
(UV CURING ADHESIVE)

INTRODUCTIONS

JELCON RAYTACK-10N is pressure-sensitive UV curable adhesive for screen printing which has excellent printability, precision and adhesion. Ink film with excellent adhesion is formed with UV irradiation. No organic solvent is contained in its components. RAYTACK-10N has good both in the strength against peeling-off and maintaining its adhesion. The odor of RAYTACK-10N is low.

CHARACTERISTICS

1. Excellent printability
   As the ink cures at lower temperature than conventional water-based or solvent- based pressure-sensitive adhesive, precision is improved, which leads to better productivity.
   As no solvent is contained, viscosity is stable. No clogging occurs. It is easy to wash the stencil.
   As the component is 100% non-volatile, the thickness of ink film is stable. It is possible to print thick film.
2. Excellent adhesion & adhesion-maintaining

HOW TO USE

1. The product is supplied in ready-to-use condition. Stir well before use.
2. Screen: Stainless 80-150 meshes/inch or polyester 60-200 meshes/inch.
   The thicker the ink film is, the better the adhesion becomes.
3. Use the product in the environmental temperature of 20-30°C(68-86°F) avoiding direct sunshine.
4. Use our VINYL CLEANING THINNER to wash up stencils.

CURING CONDITIONS

• UV lamp: one metal halide lamp 120W/cm
• Integral light: 500mJ/cm²

COVERAGE

10-40 m²/kg

TYPE OF PACKING

1-kg-plastic-container

PRECAUTIONS

1. Please refer to the literature "UV INK" for general precautions.
2. As RAYTACK-10N is non-silicone, crawling may happen by the contact with silicone.
   Wash printing equipments (stencil, squeegee, scrapers) well before print.
   The small addition of silicone de-foamer can solve this problem although the strength against peeling-off and adhesive-maintaining are degraded.
3. Use separator whose silicone migration is small.
4. Please refer to MSDS before use.
5. Be sure to do trial print before commercial run to confirm that the product fits the purposes.

Print and test conditions

Substrates	treated PET film 125 microns(Higashiyama film HK-31WF)
Stencil	150 mesh/70 meshes , 25x100 mm, solid print
Adhesion	After the ink was adhered to stainless steel plate using a 5-kg-rubber roller, leave it at room temperature for 1 hour.
Strength against peeling-off	Digital force gauge PGD-20 is used. Peak load to stretch the printed matter to horizontal direction.
Adhesion-maintaining	The time until the printed matter peels off from stainless steel plate, when 0.5-kg-load is added to vertical direction.
