Liquid sodium silicates
are versatile and economical adhesives.They are used
to manufacture such products as:
sodium and potassium silicates
Fiber Drums
Cornerboard, Angleboard
Paperboard Laminates
Paper/Metal Foil Laminates
Corrugated Board
Silicate solutions may be applied either by cascade, immersion,
or transfer roller systems. It is best to use notched scraper
bars to form a thin bead of silicate on the paper. Typically,
sodium silicate is diluted with water to achieve good penetration
of the silicate into the paper. As water from the silicate is
absorbed into the substrate and evaporates into the air, the
silicate becomes tacky and sticky. Then the silicate dries to
form a hard, glassy bond.
National Silicates' Technical Service Group supports this
end use by providing guidance in product selection, blended
products, control of processing variables (for example, operating
temperature and silicate viscosity), trouble-shooting, safety,
and housekeeping.
When tube strength and adhesive costs are at issue, our sodium
silicate is the paper adhesive of choice. Silicate also provides
the benefits of being environmentally friendly, non-toxic, non-flammable,
odorless, and resistant to oil, grease, heat, and microbial
activity.
