Bio-adhesive · PB-01 & PB-02
Advanced Bio-Based Adhesive Technology for Plywood & Wood Based Panel Manufacturing
Engineered as a highly advanced, dual-component bio-adhesive system to reduce reliance on conventional synthetic petrochemical-based resins. The condensation reaction between PB-01 and PB-02 forms a fundamentally robust, three-dimensional polymer network that ensures superior structural integrity.
PB-01 & PB-02
Bio-Based Adhesive
A dual-component bio-adhesive system that replaces up to 50% of urea content and cuts reliance on synthetic petrochemical resins.
Applies to
Revolutionizing Wood Panels with PB-01 Additive and PB-02 Cross-linker
Conventional plywood adhesives lean heavily on urea- and phenol-formaldehyde resins drawn from petrochemicals. As feedstock prices swing and emission rules tighten, that dependence has become both a cost risk and a compliance risk for panel makers. The PB-01 / PB-02 system was engineered as a practical answer — a bio-based chemistry that carries a real share of the bonding load rather than acting as a token “green” additive.
PB-01 supplies reactive, soya-derived functionality carried on specialised bio-based catalysts, while PB-02 is a liquid crosslinker tuned to react with the amino groups PB-01 introduces. Cured together they condense into a dense, three-dimensional polymer network — the same kind of load-bearing lattice a synthetic resin builds, but with a materially lower synthetic fraction.
Because the pair is designed around existing glue-mixing and pressing equipment, adoption does not mean re-tooling a line. Mills can trial the bio-adhesive against their current formulation, verify bond strength and emissions on their own presses, and scale the substitution as confidence grows.
Why it matters
- Replaces up to 50% of urea content in traditional adhesives
- Non-urea alternative that lowers carbon footprint and VOCs
- Drops into existing lines with no specialised re-tooling
Grades in this range
Bio-Based Additive
- Formulation
- A blend of sustainably sourced soya-based components integrated with specialised bio-based catalysts.
Cross-Linker
- Function
- A specialised liquid crosslinker designed to target and react chemically with the amino groups present in the PB-01 formulation.
Industrial applications & performance benefits
- Significantly improves the inter-layer bonding strength and shear resistance of commercial and architectural plywood panels.
- Functions as a direct substitute for high-emission adhesives, letting manufacturers seamlessly formulate low-formaldehyde plywood adhesives.
- Excellent compatibility with existing industrial production lines and machinery — no specialised re-tooling required for integration.
Economic & environmental advantages
- Dramatically reduces overall synthetic resin consumption within the manufacturing facility.
- Substantially reduces the aggregate cost of adhesive formulations versus 100% synthetic petrochemical-based resins.
- Acts as a highly effective non-urea-based adhesive alternative.
- Capable of replacing up to 50% of the urea content in traditional urea-based plywood adhesives, lowering both carbon footprint and VOC output.
Where it goes to work
Putting PB-01 & PB-02 on the line.
Commercial plywood
Raises inter-layer bond strength and shear resistance in everyday commercial ply without changing the press cycle.
Architectural & decorative panels
Supports the cleaner, low-emission bonds increasingly specified for interior-grade panels.
Low-formaldehyde formulations
Forms the base for E0 / E1 adhesive systems, replacing a large share of the urea that drives emissions.
Questions
About Bio-Based Adhesive.
Up to 50% of the urea content in a traditional urea-based plywood adhesive, which lowers both carbon footprint and VOC output.
No — it is compatible with existing production lines and machinery, so no specialised re-tooling is required to integrate it.
Yes — the PB-01 / PB-02 condensation network is built for structural integrity and improves inter-layer bonding and shear resistance versus the adhesive it extends.
