Hirenol Epoxy modifiers: advantages based on methylstyrenated phenol versus styrenated phenol

Due to new legislations and SVHC listing, alternatives based on styrenated phenol are preferably changed into Hirenol series. The Hirenol PL series is used in a lot of different applications such as a non-volatile viscosity reducer, as a reducer of brittleness and Shore Hardness by flexibilising. It can also improve anti-corrosion properties, act as a carrier for high loaded pigment pastes and could be an alternative for nonylphenol and benzyl alcohol in epoxy hardeners.

Advantages of Hirenol PL (methylstyrenated phenol)

The Hirenol PL series-based on methylstyrenated phenol provides a lot of advantages over styrenated phenol versions which are currently available in the market:

•    Hirenol PL is only labelled with (!) marking and less labelled than styrenated phenol.

•    Hirenol PL has lower viscosities.

•    Hirenol PL has better properties in water contact applications.

•    Hirenol PL is non/less bleeding.

•    Hirenol PL has lighter colour.

•    Hirenol PL is better non-crystalizing at room temperature.

•    Hirenol PL has better wetting properties.

•    Hirenol PL enhances pot-life (higher -OH version).
