Properties

Appearance

White crystalline powder

Melting Point

>90°C

Solubility

From our aspect, we would suggest using dichloromethane as the solvent, other choices are MTBE, toluene or other eithers.
Water, methanol or ethanol should be avoided, because 4-META would resolve in them and the structure would change.

Application

It is usually used together with 10-MDP CAS 85590-00-7 as an adhesive in dental area.

Recommended Formulation Use

Research has found that methacrylates with both hydrophobic and hydrophilic groups, like 4-META, enhance monomer
penetration into dentin pretreated with 10% citric acid and 3% ferric chloride (10-3). Examinations revealed the formation of a transitional zone of resin-reinforced dentin, termed the hybrid layer. The 4-META contains two functional groups facilitating a bridge between tooth and adhesives.
