alkyd resin

Thân thiện

An artist mixes alkyd resin into a can of oil paint.

Definition

Noun: A synthetic resin made by combining a polyhydric alcohol (like glycerol) with a polybasic acid (like phthalic anhydride). It is modified with drying oils, fatty acids, or other compounds to produce a durable, versatile material that dries to form a hard, protective film.

Usage

Alkyd resin is primarily used as a key binder or film-forming agent in industrial and household products. Its main function is to provide durability, gloss, and adhesion.

Examples

• The paint's durability comes from its high concentration of alkyd resin.
• Alkyd resin is a common component in many glossy enamels and varnishes.
• This adhesive formula incorporates a modified alkyd resin for improved water resistance.

Advanced Usage

• In technical contexts, "alkyd" is often used as a shorthand for "alkyd resin," especially when describing paint types (e.g., "alkyd paint" vs. "latex paint").
• The properties of an alkyd resin (such as drying time and flexibility) are determined by the specific oils (e.g., soybean, linseed) used in its modification.

Variants and Related Words

• Alkyd (noun/adjective): The shortened form. As an adjective, it describes products made with this resin (e.g., alkyd enamel, alkyd coating).
• Polyester Resin: A broader category of synthetic resins; alkyd resins are a specific, oil-modified type of polyester resin.

Synonyms

• Synthetic resin (specific type)
• Oil-modified polyester resin (technical synonym)

Related Phrases/Compounds
