resol
resol — noun
1. A chemical substance formed in the first stage of making phenolic resins — a typ
A chemical substance formed in the first stage of making phenolic resins — a type of strong, heat-resistant plastic. Resol can be melted and dissolves in alkaline liquids or alcohol. It is mainly used to coat or soak into materials such as paper and fabric before they are pressed into hard sheets or shapes.
The factory uses resol to coat paper sheets that are pressed into countertops.
collocation: use resol to coat [material]
Dario mixed phenol and formaldehyde with a catalyst to produce resol in the lab.
verb collocation: produce / synthesize resol
Unlike finished phenolic plastics, resol can still be melted and reshaped by heating.
The engineering team chose resol-impregnated fabric for its strength and heat resistance.
Rachid tested whether the resol would remain soluble after six months of storage.
- A-stage resin
The same material, named by its position in the curing process — used interchangeably with resol in industrial chemistry.
- resole
Alternative spelling, less common but still found in older or British technical publications.
- phenolic resin precursor
A broader descriptive term that includes resol as well as other early-stage phenolic intermediates.
- resite
The final, fully cured stage of phenolic resin — opposite of resol in terms of solubility and fusibility.
文法句型
resol + is produced from [chemicals]
resol + is used for [purpose]
用法筆記
Resol is an uncountable noun in technical writing. It is one of three stages in phenolic resin chemistry — resol (A-stage, soluble and fusible), resitol (B-stage, partly cured), and resite (C-stage, fully cured and infusible). Resol is also spelled resole in some textbooks, though the shorter form is more common in modern chemistry.
