Product Detail
ACCU Dyne Test Pen

Product Description

Dyne solutions may work well in the lab, but in the shop a more robust device is indicated. This suggests "dyne pens" for online testing. Several types are readily available.

Most rudimentary is a nominal go/no go tester: Above a certain treatment, this pen marks the surface; below this level, the ink disappears. These pens identify and permanently mark the treated side of PE and PP films — aside from this, they have little use, since their initial accuracy is undocumentable and their design is subject to contamination.

A second style is formulated at several dyne levels, enabling the user to test over a range of treatments. Generally, these markers are interpreted based on which dyne level takes closest to two seconds to form beads (similar to the standard ASTM and TAPPI methods). These test markers are easy to use and, when first used, often quite accurate.

This dynamic interaction between the instrument and the substrate essentially eliminates such wicking style applicators for serious dyne testing.

Advantages

• 16 Standard levels, from 30 through 60 dynes/cm

• Specifically designed for fast, accurate on-line use by printers, coaters, and laminators — also ideal for process control or field use by suppliers of film, sheet, coated board, inks, coatings, and adhesives

Spring loaded tip meters fluid feed and guards against contamination

Reliable enough for many R & D and lab applications

Hundreds of tests from each marker

Usable on virtually all smooth non-absorptive substrates

Specify any combination of dyne levels and quantities you require (minimum order four pens)

Usage

(1)Some values theoretical.

(2)Any density, any type, including films, coated board, and molded products.

(3)All types; cast or molded.

(4)More plasticizer generally requires levels at the high end of these ranges.

(5)Uncoated.

(6)For heat sealing, the surface energies of the mating PE surfaces should match closely; if both faces are treated, heat sealing can usually be accomplished over a broader and lower temperature range.
