Effects of Nanoclay Modification with Aminopropyltriethoxysilane (APTES) on the Performance of Urea–formaldehyde Resin Adhesives [PDF]

open access: yes, 2023
Urea-formaldehyde (UF) resins, as the most common adhesives for wood-based composites, emit formaldehyde, which is forcing producers to find a solution to this problem. Using scavengers is a practical way of reducing formaldehyde emissions, but sometimes

Preparation and characterization of urea-formaldehyde resin/reactive kaolinite composites

open access: yes, 2016
Novel urea-formaldehyde resin/reactive kaolinite composites containing 20-40 wt% kaolinite were prepared by in situ polymerization. The kaolinite was modified with tetraethoxysilane and a silane coupling agent to introduce reactive groups.
