Wood stabilization is a subset of wood preservation processes specifically used by woodworking enthusiasts to alter the material properties of specific wood species for applications within their craft or trade. Examples of wood items which are commonly stabilized include knife handles, pistol grips, straight razors, game calls and jewelry.
These can become polymer solutions upon curing inside of a wood substrate, imparting stabilizing properties. Impregnation of these resins involves a vacuum chamber procedure that completely disperses the resin into the wood. Once inside of the wood, the resin can diffuse into the cell wall and enhance the physical strength of the wood even ...
The resin often contains a significant amount of filler. The most common fillers are calcium carbonates and aluminium trihydrates. In filled resin systems, fillers replace some of the reinforcements; 5 to 25% filler is used by weight. Steel, wood, GRP, and other materials are used as mould materials for prototyping purposes. The mould can be a ...
