TECDUR
Glass Protection Ballistic utilises a clear resin that
is poured between an outer and inner surface of glass polycarbonate.
The thickness of the glass, resin and or polycarbonate determines
the performance level of the protection.
Tecdur Glass Protection Ballistic
is best suited to applications where traditional glass/glass
laminations or glass/polycarbonate laminations are not good enough.
This might be due to weight, clarity, temperature range or the
shape of the protection required.
 Weight
Tecdur Glass Protection Ballistic can be up to a third lighter
than typical glass/glass laminations. For example, an armoured
car requiring 4 sq m of BR6 glass could save the weight of a
grizzly bear by using Tecdur rather than traditional glass laminations.
Clarity
At the higher level of protection typical glass or glass/polycarbonate
laminates lose clarity and exhibit a green tinge which often
makes armoured cars distinctive. Tecdur glass has a light transmittance
of 85% to 90% whereas similar protection with a glass/glass laminate
would typically be as low as 60%.
Extended Temperature Range
As the resin cures with minimal shrinkage and the resin and glass
share similar coefficients of expansion, there is a reduced stress
in the bond. Also, a chemical bond is formed, rather than a weaker
physical bond typical of other systems. Hence an extended temperature
performance range is achieved, for example, at minus 17 degrees
Celsius it continues to protect where most polycarbonate systems
fail.
Curved Applications
As the resin is poured it can be utilised in complex curves such
as with a curved front windscreen of an executive car or vision
domes.
