| Q. |
Over a period of time, even with daily
maintenance and cleaning, I still get tough-to-clean build-up
of adhesive on my gluing equipment, rollers, floors, etc.
I have tried everything to remove this build up but nothing
works very well. Do you have any suggestions? |
| A. |
You couldn’t have asked this
question at a better time, we have just introduced a wonderful
new cleaning product called “Soyclean”. It’s
non-toxic and biodegradable, and boy, does it do the job!
Spray it on, let it soak in, and wash it off. Call today
for a bottle, pail or drum. You will be impressed.

| Q. |
I often hear the word “humectant”
when discussing water-based adhesives. What does this
mean? |
| A. |
A humectant is a hydroscopic substance
that absorbs and retains moisture from the atmosphere.
In water-based adhesives, humectants prevent the surface
of the adhesive from skinning by keeping it wet. By retarding
drying, humectants also slow adhesive setting speed and
extend its open time. In addition, humectants allow easier
cleanup of dried and semi-dried adhesive.

| Q. |
If an adhesive has a Ph of 5.9 and
the user must have an acid-free adhesive, can you do anything
to the adhesive to accomplish this? |
| A. |
Absolutely! This is a process commonly
known as buffering the adhesive. A substance such as Sodium
Bicarbonate can be added to the formula in small amounts
to reach the neutral Ph. The principle here is the same
as when a person has acid indigestion and he/she takes
an antacid, which neutralizes the acid and makes that
person feel. Better.

| Q. |
I often hear the term“acid-free”
when referring to adhesives or paper materials. What does
this mean? |
| A. |
Acid-free is a term describing materials
with a Ph value of 7.0 or higher. Materials with a Ph
level of 7.0 are neutral and considered acid-free and
those with a Ph level greater than 7.0 are alkaline.
