1、Curing kinetics and mechanical properties of epoxy resin/1

The epoxy resin of diglycidyl ether of bisphenol A (DGEBA) diluted with allyl glycidyl ether (AGE) was mainly cured by 1-benzyl-2-methylimidazole (1B2MZ). Then, the effect of isophorone diamine (IPDA) on the properties of DGEBA-AGE-1B2MZ system was investigated.

2、Epoxy Curing Agents

Clear and pigmented coatings based upon Amicure® IC curing agents exhibit very rapid hardness development, excellent low temperature cure, very good color and UV stability and excellent surface appearance.

3、Benzyl Alcohol as a Diluent for Epoxy Curing Agents

Benzyl alcohol is a versatile co-solvent used in a wide range of curing agent formulations for epoxy resins used in coatings, flooring systems, adhesives, etc. The product can also be used as a co-catalyst and plasticizer and to keep the temperature low during the curing process.

4、Epoxy Curing Agents

Epoxy curing agents are often modified to improve certain properties. The modification may be to partially react the curing agent, to reduce induction time, and increase compatibility. Common additives are nonylphenol (accelerator and diluent) and benzyl alcohol (diluent and plasticizer).

5、Honrepoxy resin, curing agent, hardener

With a professional R&D team and a domestic first-class laboratory, we have successfully developed modified aromatic amines, aliphatic amines, alicyclic amines, phenalkamines, polyamides, cardanol-based epoxy resin curing agents, and water-based epoxy curing agents.

Benzyl Alcohol in Epoxy

Benzyl alcohol is well known for its superior solubilzing functions in epoxy system and is found to be very useful significantly in facilitating application. It has the ability of rapidly dissolving different epoxy resins, resulting in development of better mixing, spreading and application ease.

Solvent Effects on Cure 1

Benzyl alcohol lowers the viscosity, aids cure and plasticizes the final product. Phenol and triethylenetetramine [TETA] significantly enhance the rate of cure and have a catalytic effect.

The Role of Benzyl Alcohol as an Epoxy Resin Solvent and Curing Agent

Benzyl Alcohol serves a dual purpose within epoxy resin applications: it functions as an effective solvent and a modifier for curing agents. As a solvent, it aids in reducing the viscosity of epoxy formulations, making them easier to mix, process, and apply.

Epoxy resin dilution accelerator

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.

Accelerators for Amine Curing Agents

Because the stoichiometry is 1:1 between the accelerator and the epoxy, accelerators such as benzyl alcohol and salicylic acid are added in higher than catalytic amounts in the formulation, and they can typically be as much as 30-40% of a blended amine curing agent.

In modern industrial and construction fields, the selection and application of materials are one of the key factors to ensuring engineering quality and performance. Among them, epoxy resin, as a high-performance thermosetting resin, is widely used in coatings, composites, adhesives, and other fields due to its excellent mechanical properties, chemical resistance, and electrical insulation.
