Discription:

C70 Multigrip is a low-odor, fast-drying, multi-purpose, high-gloss ink with excellent outdoor durability and adhesion to a wide variety of paper and plastic substrates.

Substrates and Applications:

C70 Multigrip may be screen printed onto pressure-sensitive vinyl, rigid vinyl, styrene, most polycarbonate, surface-treated polyester, acrylic, most coated paper/board and some fiberglass surfaces. If ST-355 Adhesion Promoter is added, C70 Multigrip may also be printed on fluted polypropylene sheet such as Coroplast™, Hycor™, Cor-X™ or other, similar substrates. C70 Multigrip is recommended for printing P.O.P. displays, vacuum formed products, bookcovers, membrane faceplates, advertising specialties, novelties and many other display and packaging applications. NOTE: On fluted polypropylene C70 Multigrip loses abrasion resistance and adhesion when exposed to water. After drying off, these properties are restored. Do not use C70 on fluted polypropylene when wet abrasion-resistance and adhesion is required, such as for rain-wet exterior signs which may be abraded during handling. An alternative Coates Screen product, the DA series, is recommended for these conditions.

Although multiple-layers of C70 Multigrip may be successfully superimposed, flexibility will gradually decrease as total ink deposit increases. If exceptional flexibility is required, a more flexible ink, such as C99 Gloss Vinyl or C37 Flexiform, may be more suitable. Adhesion may be adversely affected by the inherent properties of certain substrates, sometimes a considerable period after printing. For example, plasticizer can migrate onto the surface of self-cling vinyl; calendared vinyl may be manufactured with lubricants to enhance surface slip; higher-gauge plastics may be contaminated by adhesive left after removal of their protective sheets.

NOTE: Pretest all substrates prior to use in production.

Drying:

C70 Multigrip is fast drying with excellent screen stability, and is therefore especially suitable for use on high-speed screen printing equipment, such as cylinder presses or reel-to-reel label presses. Single layer prints of C70 Multigrip can dry in as little as 10-15 seconds at 140°F (60°C) through a jet dryer. With solvent-based inks, subsequent ink layers may require slightly longer drying time.

Process Colors:

All process colors match the SWOP standards. Color density may be adjusted by adding C70-S139 Process Base.

Coverage:

Typically 255-305/inch (100-120/cm) mesh. Finer meshes may be used for 4 Color Process printing.

Screen Mesh:

Using a 255/inch (100/cm) mesh, one gallon of C70 Multigrip will cover approximately 1,500 square feet.

Stencil:

Direct photo emulsion, capillary film or other solvent resistant stencil.

Squeegee:

Medium to hard durometer urethane squeegee.

Modification:

Viscosity Reduction: For best results, C70 Multigrip may be reduced with approximately 10-20% by weight of ST-212 Reducer. For exceptionally fine detail printing, or under adverse ambient conditions, either ST-303 Retarder or GEL-100 Gelled Retarder may be substituted for all or part of the reducer. The restricted flow of GEL-100 allows better print definition, particularly for reverse detail or 4 color process printing. NOTE: The use of ST-303 Retarder or GEL-100 Gelled Retarder may decrease drying speed; ensure that drying is adequate before commendng a full production run.

Gloss Reduction: Up to 20% by weight of Matte Additive MAT-190 may be used to reduce gloss. A 10% addition of MAT-190 allows a satin finish, whereas a 20% addition allows a less reflective, more matte finish. NOTE: As with all inks, decreasing gloss may render prints more susceptible to slight surface scuffing.

Adhesion Promoter: Adhesion of C70 Multigrip to fluted polypropylene sheet may be achieved by the addition of 1% by weight of ST-355 Adhesion Promoter. After addition, ink will only be useable for 24-48 hours.

Overprinting:

C70-E50 Mixing Clear may be used to overprint C70 Multigrip colors. For maximum exterior durability an alternative product, OPC-190 Overprint Clear, is recommended. OPC-190 is specially formulated for use only as an overprint clear, and is slightly slower drying than C70 Multigrip products. If required, OPC-190 may be reduced with 5-15% by weight of ST-280 Overprint Clear Reducer.

NOTE: Pretest OPC-190 prior to use in production.

Wash-up:

C70 Multigrip may be cleaned off screens and processing equipment with any suitable screen wash, such as VL Wash.
