increased, formaldehyde emission also increased. The
reduction ratio of formaldehyde emission was much
higher than the reduction ratio of bonding strength,
when 30% of PVA c was add ed. It is possibl e to reduce
form aldehyde emission with just smal l de creasing
bonding strength by ad ding just 30% of PVAc.
When we blended MF resin and PVAc toget her,
wheat flour was used as mate rial to increa se the quantity
and viscos ity
