3. GENERAL PROCESSING GUIDELINES<br />
3.3 BONDING EDGES<br />
There are several different ways to attach the <strong>Varicor</strong> ® 3 <strong>mm</strong> edges to<br />
the workplace.<br />
3.3.1 BONDING THE EDGE UNDER VARICOR ®<br />
Two different work procedures are available to bond the edge under-<br />
neath the <strong>Varicor</strong> ® 3 <strong>mm</strong> coating:<br />
1. Attaching the edge after coating the chipboard<br />
• Fold a coated plate near the edge to a width of 4 <strong>mm</strong>.<br />
• Let a surplus of 4 <strong>mm</strong> of the <strong>Varicor</strong> ® 3 <strong>mm</strong> coating.<br />
Remove dust with clean, dry compressed air.<br />
• Apply <strong>Varicor</strong> ® adhesive to the projecting length and apply PVAC<br />
glue on the back of the <strong>Varicor</strong> ® 3 <strong>mm</strong> edge over the whole surface.<br />
• Fix the edge with the aid of bonds and clamps.<br />
• Once the <strong>Varicor</strong> ® adhesive has hardened, furnish the edge with<br />
a 3 <strong>mm</strong> radius.<br />
• Pressing time: as specified by the manufacturer of the adhesive.<br />
The edge can also be bonded over the whole surface with <strong>Varicor</strong> ®<br />
adhesive to the substructure. It is possible to apply the <strong>Varicor</strong> ®<br />
3 <strong>mm</strong> edge with hot-melt adhesive using a special edge bonding<br />
machine. First apply the <strong>Varicor</strong> ® adhesive to the excess length<br />
of the <strong>Varicor</strong> ® 3 <strong>mm</strong> coating!<br />
2. Attaching the edge prior to coating the surface<br />
• Apply PVAC glue to <strong>Varicor</strong> ® 3 <strong>mm</strong> edge strips and glue them to the<br />
edge of the chipboard. <strong>Varicor</strong> ® 3 <strong>mm</strong> strips must project slightly.<br />
• Adjust the <strong>Varicor</strong> ® 3 <strong>mm</strong> edge to the length of the carrier material.<br />
• Attach 10 <strong>mm</strong> wide adhesive tape on the upper side of the chipboard<br />
with the bonded <strong>Varicor</strong> ® 3 <strong>mm</strong> edge.<br />
• Apply the PVAC glue to the chipboard.<br />
• Peel off the adhesive tape and apply the <strong>Varicor</strong>® adhesive to the<br />
<strong>Varicor</strong> ® 3 <strong>mm</strong> edge.<br />
• Lay on the <strong>Varicor</strong> ® 3 <strong>mm</strong> coating and the HPL counteracting plate.<br />
• Press the individual materials together.<br />
• Once the <strong>Varicor</strong> ® adhesive has hardened, furnish the edge with<br />
a 3 <strong>mm</strong> radius.<br />
3.3.2 BONDING THE EDGE IN FRONT OF THE SANDWICH<br />
PANEL<br />
• Format the sandwich panel.<br />
• Cut <strong>Varicor</strong> ® 3 <strong>mm</strong> edge to the edge of the sandwich panel with<br />
bonds.<br />
• Once the <strong>Varicor</strong> ® adhesive has hardened, furnish the edge with<br />
a 3 <strong>mm</strong> radius.<br />
Attention: In this case there is a risk that the bonded joint is more<br />
obvious because it runs along the edge.<br />
Important:<br />
Seal all of the open edges of the substructure with hot melt<br />
adhesive edges or sealant to prevent the absorption of water.<br />
