<p>This invention relates to ethyleneurea-glutaraldehyde resins, urea-ethyleneurea-glutaraldehyde resins, their synthesis, as well as their application as an adhesive for wood panel manufacture. Molar ratio of ethyleneurea to glutaraldehyde can range from 0.3 to 3.5. Urea incorporated into ethyleneurea-glutaraldehyde resin can be as high as two times the moles of glutaraldehyde used in the formulation and can be introduced at any stage during the reaction course, simply post added, or any combination of the above.</p> |
