Benzyl Alcohol Definition

Benzyl Alcohol abbreviated as BA, a highly soluble, colourless, low viscosity liquid. Also known as benzyl alcohol. Benzyl alcohol is the simplest fatty alcohol containing phenyl, and may be regarded as hydroxymethyl-substituted benzene, or phenyl-substituted methanol.

It is a colourless transparent viscous liquid with a faint aromatic odour, polar, low toxicity and low vapour pressure, hence its use as an alcohol solvent. It is flammable. Slightly soluble in water (4 g/100 mL), miscible with ethanol, ether, benzene chloroform and other organic solvents.

Benzyl Alcohol Uses

Benzyl alcohol is an excellent solvent with medium boiling point, mainly used in:

Epoxy resin diluent, curing agent, solvent, plasticizer; epoxy coatings; pharmaceutical synthesis and solvent, preservative of ointment or liquid; photographic developer, welding mouth cleaner, solvent for plexiglass, lens tinting agent; meat and food printing oil and ball-point pen oil solvents, solvents for printing inks; aroma fixing agent, jasmine, incense, ylang ylang, etc., fragrance blending is an indispensable spice. It can also be used to formulate soap and daily-use cosmetics.

Advantages of benzyl alcohol for epoxy diluent

• Epoxy resin curing agent 1,3-BAC, AEP, IPDA, D-230 and other modification of the necessary solvents
• The material itself is non-toxic (can be used for human injection reagents)
• High boiling point, non-volatile, and after curing due to the strong polarity of benzyl alcohol, can be very good with the epoxy resin, will not migrate phenomenon
• Benzyl alcohol can promote the reaction of epoxy resin and amine, speed up the reaction speed; benzyl alcohol has a very good hydrophobicity, can be used in epoxy diluents
• Benzyl alcohol has good hydrophobic properties, can significantly improve the gloss of the coating, reduce the phenomenon of whitening
• Benzyl alcohol can improve the toughness of the cured material

Benzyl alcohol as epoxy resin diluent application fields

Benzyl alcohol can be applied to epoxy flooring, epoxy potting, epoxy solvent-free coatings, epoxy trim adhesive, amine curing agent modification and so on.

Typical data of benzyl alcohol

• Appearance: colourless transparent liquid
• Refractive index: 1.538-1.541

Matters to be noted in the use of Benzyl Alcohol

• Benzyl Alcohol needs to be stored away from light, otherwise it will turn yellow and other phenomena
• It can only be used in epoxy resin/amine curing system, especially not in epoxy resin/anhydride system;
• To control the amount of addition, because the addition of benzyl alcohol will reduce the mechanical properties of the cured material, solvent resistance and chemical resistance, so it is necessary to determine the proportion of addition according to the actual requirements, in addition, benzyl alcohol can significantly improve the curing speed, so this point needs to be taken into account.
• Benzyl alcohol is used as a diluent by many manufacturers in practical applications, especially for diluting the curing agent.
