E-850???

What the hell is E-850?

What is a resin? What is adhesive?

Well, this tape is adhesive ;-) These are resins.

This still doesn’t make sense, right?

It is simple,E-850 is a new main component for glue developed by

It suffers less from fatigue

It is very strong

&

E-850

It is water borne

It is formaldehydeIt is VOC-Free

E-850It is formaldehyde free!!..

However...One

important issue

remains

http://www.simonstapleton.com/wordpress/wp-content/uploads/2009/07/one-finger.jpg

During application of a water borne lacquer,

de-lamination occurs at the edges of the laminate....

and so far, we cannot solve this....

This is what happens...

11

The adhesive film does not dissolve in water

Conclusion: The adhesive itself is not water sensitive

...and this is what we

tried and learned

ourselves already

Delamination most probably does not occur during application

of the lacquer, but only during/after drying.

Delamination also occurs by applying water instead of the lacquer

Conclusion: Water is responsible for delamination, not an ingredient in the lacquer

There is still adhesive present on the two delaminated sides

Conclusion: Adhesion to wood is good enough

Without lacquer, the

mechanical properties of the laminate are good and outperform current adhesives --

> the adhesive is strong enough

So this is where we

need

you!!
