Bondo is a polyester putty product originally marketed as an automotive body filler. Nowadays the brand name is used by 3M for a line of American-made products for automotive, marine and household repairs. [1] [2] The term Bondo is trademarked by 3M, but is commonly used to refer to any brand of automotive repair putty due to its popularity.
Pore fillers used for large flat surfaces such as floors or table tops generally contain silica instead of or in addition to wood dust. Pores can also be filled using multiple coats of the final finish rather than a pore filler. [1] [2] The main problem in using putty is matching the colour of the putty to that of the wood.
When it finally polymerizes in a wood joint, enough gel remains for a better bond than with the thin version. When using the gel, too much glue will weaken the resulting bond. Likewise, applying too little of the thin super glue will result in almost no glue at all remaining in a wood joint, causing a weak bond or no bond at all.
In this case, the plastic at the substrate surface is dissolved by the solvent contained in the adhesive. This leads to an increased mobility of the plastic's polymer chains, which in turn allows penetration by those of the adhesive. Ultimately, additional interactions occur between the polymer chains of the adhesive and the substrate.
The joints between pieces of wood (natural or processed), between materials similar to joint effects (for example, plastic foam boards) and combined materials can be various. If the parts to be joined include (in addition to wood) metals, ceramic materials or polymers, the joints can be more elaborate.
Plastic consumption uses by field. Filler materials are particles added to binders (resin, thermoplastics, cement) to make a composite material. Filler materials improve specific properties or make the product cheaper. [1] Coarse filler materials such as construction aggregate and rebar are used in the building industry to make plaster, mortar ...
