An amino-alkyl siloxane oligomer as hydrophobation agent for particleboards used under high humidity conditions
In this study, an amino-alkyl siloxane oligomer was used as a
hydrophobation agent in order to improve the behaviour of particleboards
under moist and outdoor weathering conditions and to be compared to
conventionally used paraffin waxes. Melamine-urea-phenol-formaldehyde
(MUPF, 15.0 \%) was used as adhesive and mixed with the hydrophobation
agents at concentrations of 1, 3, and 5 \% related to the dry particle
mass. The siloxane oligomer improved the water-related properties
(thickness swelling, water uptake, internal bond strength (IBS) and IBS
after boil test) in comparison to a control without hydrophobation
agent. It also tended to enhance bending strength, modulus of
elasticity, and IBS compared to specimens containing wax. IBS after boil
test was significantly higher at addition of 3 and 5 \% siloxane than
that of wax-added reference boards. Specimens with siloxane oligomer,
however, displayed higher thickness swelling and water uptake than those
with wax added. It is assumed that the siloxane oligomer is able to
contribute to bonding via hydrogen and covalent bonds and particularly
enhance wet strength, while waxes exclusively act by their non-polar
nature and, thus, water repellent behaviour
