文摘

Bark extraction and HTL-oil fractionation led to more free formaldehyde in BPF resoles.

HTL-oil introduction into PF resole promoted the curing of BPF resole.

All the BPF resoles met the JIS standard as plywood adhesives.

Bark extraction reduced the water resistance of BPF resole.

HTL-oil fractionation improved the water resistance of BPF resole.
