“A SOLUTION FOR REACH Classified Borates”
CARRIER GEL eliminates 100% the use of borates.
Eliminates all pre-cooked carrier starch.
It’s specific polymer’s characteristics enables a perfect tack, rheological behavior, shear-thinning, water retention and a very stable viscosity without any use of borates.
This is more than welcome in Europe where borates has been classified on the REACH list.
BENEFITS
-
A very simple “system” to produce fast & stable batches time after time
-
Enables to use all types of starches with a preference to the cheapest native unmodified starches you’ll find on the market
-
Enables the use of native wheat FLOUR instead of starch
-
100% of the starch or flour is used as adhesive – no need for carrier starch
-
Excellent Rheological Modifier with high shear-tinning properties
-
Important savings in adhesive consumption
-
Very thin glue line
-
Very short glue structure – no spinning or splashing – only adhesives at the flute tips
-
Enables very important energy savings.
-
Board production with very low temperatures
-
Zero borate
-
Very flexible adhesive formulations with low dry solids. Example 23% at double glue unit bonding all types of paper
-
Important paper waste reduction
-
No zipper board at low speeds
-
Simplified glue kitchen – process
-
Flat board – zero washboard –
-
Enables production Food contact packaging CMR FREE
-
Very easy to introduce in all existing glue kitchens with very low investments
Unlike most of traditional adhesive formulas like Stein-Hall or others using a part of precooked gelatinized starch as carrier to suspend the secondary starch, CARRIER GEL acts as the carrier of 100% of the starch. This new revolutionary system enables 100% of the starch to act as a bonding agent.
With traditional formulations, the primary starch or carrier starch offers zero bonding. It only ‘holds’ the secondary starch in suspension and determines the final viscosity and gel point of the adhesive.
Viscosity & Rheology
Viscosity of traditional starch adhesive is altered by varying the amount of carrier starch or water used in the formula. In a corrugated board box plant, viscosity is determined by the needs of the machine due to the glue rolls and the rate they pick up and transfer starch to the medium. The higher the starch viscosity, the higher the end application rate is on the combined board due to the film thickness being carried on the glue roll.
The volume of CARRIER GEL determines the final viscosity of the adhesive.
The caustic determines the gelling point of the starch.
Bacteria & Viscosity
Precooked or gelatinized starch is a real appetizer for bacteria destroying the adhesive’s viscosity.
With CARRIER GEL there is no pre-cooked or gelled starch in the formula reducing considerably the risk for bacteria and a dramatic viscosity losses over a weekend.
