description
HM-40 is a white colored (pigmented) hot-melt
adhesive based on heat-stable resins and EVA
copolymer. It has medium open and setting time
values. It presents good low temperature
flexibility.
Typical
use
Perfect binding of books on medium speed
machines, where a white color and a thicker
layer of adhesive is needed.

(Open and setting time are also depending on the
thickness and temperature of the applied
hot melt. These values are the average.) |
Storage
If
the adhesive is stored in its original sacks in
a cool and dry place, a minimum stability of 12
months may be expected.
In
order to avoid caking, direct contact with
sunlight must be avoided.
Do
not stack pallets of adhesive.
Safety
Even
if correct application temperatures are
observed, hot-melts give out fumes. Proper
ventilation of working place is advised.
