Resin
Development
Designed alongside the process, not around its limitations.
Most wood-stabilising resins are borrowed from other industries. Ours is engineered from the monomer up for a single job — to move into timber, cure inside the cell structure, and bond to the wood itself.
01 — The problem
Borrowed chemistry brings inherited compromises.
Many stabilising resins began life as casting acrylics, coatings or adhesives, then were repurposed for wood. That inheritance shows up as viscosity that struggles to reach the cell wall, cure behaviour tuned for a different substrate, and no real chemical relationship with the timber the resin sits inside. We started from the opposite end — with the wood, and what a resin actually has to do once it’s in there.
02 — The approach
Three disciplines, one formulation.
Our resin development sits at the meeting point of three fields, backed by a great deal of hands-on testing.
Polymer science
Formulation from first principles — monomer selection, crosslink density and cure chemistry chosen for timber, not adapted to it.
Materials engineering
Understanding how a network behaves inside a porous, anisotropic, moisture-active material — not in a mould.
Arboriculture
Real knowledge of wood: how species, grain, extractives and moisture change what a resin has to overcome.
03 — Inside the network
From loose monomers to a solid, three-dimensional network.
Once the resin is drawn into the wood, it polymerises in place. Individual monomers link into a continuous, crosslinked framework — a rigid thermoset locked through the cell structure rather than simply resting in the lumen. The map below is a full-atom model of that framework, with each fragment picked out in its own colour.

A full-atom model of the network, coloured by molecular fragment — every atom, including hydrogens, in its fragment’s colour. Drag to explore.
04 — The difference
It doesn’t just fill the wood. It bonds to it.
The cell wall is rich in hydroxyl groups — the same chemistry behind wood’s love–hate relationship with water. Our resin carries a coupling chemistry designed to react with those sites, forming covalent bonds between the resin network and the wall. Instead of a resin that merely occupies space, the stabilised material becomes chemically joined to the timber.
This is a bonding mechanism, not a performance figure. It’s why we expect the bond to hold where a purely physical fill can move — and it’s exactly the behaviour our ongoing testing is designed to measure.
05 — Engineered for timber
Every property is a design decision.
These are the behaviours the chemistry is engineered toward — the targets that shape each formulation.
Penetration
Formulated to flow into the cell structure and reach the wall — not just coat the surface.
Controlled cure
Cure chemistry tuned to set fully and predictably within the wood.
Dimensional stability
Built to resist the movement moisture drives — swelling, shrinking and checking.
Hardness & finish
Engineered toward a hard, workable, finish-ready material at the bench.
Clarity
Formulated to keep the wood’s figure and colour legible, not muddied.
Cell-wall bonding
Designed to chemically anchor to the wall, not just occupy the space inside it.
06 — How we develop
Nothing ships from a single batch.
Every formulation goes round the same loop. We change one variable, take it through the wood, and characterise what came out — then feed that back into the next iteration.
- Formulate — adjust monomers, crosslinker and cure chemistry.
- Impregnate — draw the resin into real timber.
- Cure — set the network in situ.
- Characterise — measure what changed, and how.
- Refine — carry the learning into the next batch.
07 — In context
Adapted resin vs a resin built for wood.
Adapted stabilising resin
- Repurposed from casting, coatings or adhesives
- Cure tuned for moulds or films
- Sits in the cell lumen
- Physical hold only
- One formula across every species
