ITW Trans Tech: Pad Printing Ink: Type W

INSTRUCTIONS:

NOTE: Read Material Safety Data Sheet (MSDS) Prior To Use

Ink Type W is a two-component product supplied in paste form. Hardener must be added for production use. Ink and hardener should be thoroughly mixed prior to adding thinner. During printing, the ink viscosity may be adjusted with thinner (if needed). A retarder may be added to slow drying rate during printing (normally for high room temperatures or multi-color use). Under most conditions, ink pot life will not exceed four to six hours. Recommended room temperature: 70-78 degrees F. Recommended room humidity 30-50 %

ADDITIVES: (See Additives Chart for more listings)

Hardeners: (mixing ratio, ink to additive)
• BH HARDENER ( 2 : 1 or 3 : 1 depending on customer requiements; ratio by weight).

Thinners:
THINNER B (5 to 20 % by weight) Faster
VD THINNER (5 To 20 % by weight) Medium
THINNER BGA (5 To 20 % by weight) Slower

Retarder:
TPD RETARDER (1 To 3 % by weight)

DRYING & CURING: (See Ink Drying & Curing Times Chart )
Ink TYPE W dries to the touch within one to two minutes at room temperature. Drying time may be reduced with forced hot air at 200 – 400 degrees F. Normally, full cure is achieved after five to six days depending on curing temperature time; and humidity. Heat curing is necessary for better adhesion and performance results.

COLORS: (See Color Availability Chart )
Ink Type W is available in:
• 23 Standard Opaque Colors
• Standard Metallic Colors
• Process colors
• Custom Colors Available Upon Request
• C-Mix 2000 Color Matching System

NT (non-toxic) Inks
Our NT Series Inks conform to US C.O.N.E.G. Legislation and European Standard EN 71, part 3 Safety of Toys (1989). For special applications (examples: Medical, Automotive, MIL-STD) please contact us.

USE & STORAGE INFORMATION
(For more detailed information see Material Safety Data Sheet (MSDS) for Type W Ink.

Ink Type W:
Stir ink thoroughly before removing from container. Reseal lid tightly after using.
Shelf Life: Two years (in original sealed container)

HARDENER: Reseal container immediately after using. Hardener is humidity sensitive. As moisture is absorbed, the viscosity first increases, then starts forming crystals. Do not use when crystals first appear. Shelf Life: one year (in original sealed container)

THINNER: Reseal lid tightly after using. Shelf Life: two years (in original sealed container)

RETARDER: Reseal lid tightly after using. Shelf Life: two years (in original sealed container)

STORAGE OF ALL PRODUCTS: At room temperature 60 to 80 Degrees F with low humidity.
