Actually, there is a report about urea-resin glue replacing casein glues in aircraft construction. I understand that In UK, those days, they did not use the casein glues because milk was much more important for people comsuption.<div>
I attach the report. </div><div><br></div><div>In 1967, the US Department of Agriculture published a new document, Casein Glues</div><div>Their Manufacture, Preparation, And Applicatrion:</div><div><br></div><div><div>"The principal ingredients of a casein glue are casein, water, hydrated lime, </div>
<div>and sodium hydroxide. A glue can be prepared with casein, water, and hydrated </div><div>lime. A properly proportioned mixture of these three substances will give a </div><div>glue of high water resistance, but its working life will be very short. A glue </div>
<div>can also be prepared of casein, water, and sodium hydroxide. When properly </div><div>prepared such a glue will have excellent dry strength and a long working life, </div><div>but it will not be water-resistant in the sense ordinarily applied to casein </div>
<div>glues. By adjusting the proportions of sodium hydroxide and lime, glues of </div><div>high water resistance and convenient working life may be obtained"</div></div><div><br></div><div>See the attach.</div>
<div><br></div><div>I want to use a glue for cork tiles, but also as a binder for the cork aglomerate. I apreciate all sugestions and help.</div><div><br></div><div>Thanks</div><div><br></div><div>All the best</div><div>
