Abstract
A composition for increasing the fire resistance of a wood product in accordance with a particular embodiment of the present technology includes intumescent particles, gas-containing elements, and a binder in which the intumescent particles and the gas-containing elements are dispersed. The composition is configured to form a coating in which the intumescent particles are present at a concentration of at least 1% by mass, and the gas-containing elements are present at a concentration of at least 0.5% by mass. The binder includes a thermosetting polymer curable from a liquid state in the composition to a solid state in the coating. In the solid state, the binder has a Young's modulus of at least 7 GPa.

A composition for increasing the fire resistance of a wood product, the composition comprising:
- intumescent particles;
- gas-containing elements;
- and
- a binder in which the intumescent particles and the gas-containing elements are dispersed,
- wherein the composition is configured to form a coating in which the intumescent particles are present at a concentration of at least 1% by mass, and the gas-containing elements are present at a concentration of at least 0.5% by mass.
A fire-resistant wood product, comprising:
- a wood-containing substrate having a surface;
- and
- a coating overlying the surface of the substrate, wherein the coating includes—
- at least 5% by mass intumescent particles,
- at least 1% by mass gas-containing elements, and
- a polymeric matrix in which the intumescent particles and the gas-containing elements are at least partially embedded.
A method for enhancing the fire-resistance of a wood-containing substrate, the method comprising:
- applying a binder to a surface of a wood-containing substrate;
- applying intumescent particles to the surface;
- applying gas-containing elements to the surface;
- and
- hardening the binder to form a matrix in which the intumescent particles and the gas-containing elements are at least partially embedded.
