Description:
CN3150, CN3151, and CN3152 impart structural
adhesion levels when used to bond glass substrates. These products
exhibit optical clarity and excellent color. Their low viscosities
enable low adhesive thicknesses. They also demonstrate excellent
moisture resistance for optimum substrate sealant properties.
Product features are
presented below.
Typical
physical properties for CN3150, CN3151, and CN3152 are shown
below.
CN3150,
CN3151, and CN3152 were evaluated for adhesion based on the
following UV test formulation.
Evaluations
were performed on glass-to-glass laminates. The cure radiometry
results are shown below.
UV-Visible transmission
testing was performed on 0.040" thick glass slides and
based on a three micrometer adhesive thickness. Figure 1 shows
UV-Visible transmission results for a single glass slide,
adhesive-laminated glass slides (initial), and adhesive-laminated
glass slides following fifteen minutes in boiling water (after
H20). Ideally, the adhesive-laminated
glass would exhibit optical transmission results similar to
glass without adhesive. Figure 1 shows that visual transmission
for the adhesive-laminated glass is similar to, if not better
than, that for the uncoated single glass slide. Significantly,
the fifteen minute boiling water soak had no adverse impact
on optical clarity. Although these conclusions are illustrated
using CN3152, they are equally applicable to CN3150 and CN3151.
Figure 2 shows the
lap shear adhesion results for glass-to-glass laminates based
on 0.040 inch thick glass slides and a three micrometer adhesive
thickness. The test was performed in accordance with ASTM
D3164 (0.5 inch/min; 1"x1" overlap). In all cases
the mode of failure was glass breakage, rather than adhesive
separation.
