Epoxy-reactive diluents offer a range of significant advantages, but some disadvantages need to be noted. Here is a detailed analysis of its pros and cons:

advantage

Environmental performance:
Epoxy-reactive diluents usually do not contain harmful substances such as halogens and comply with environmental protection requirements.
Less volatile matter and little impact on the environment.

Strong dilution ability:
It can effectively reduce the viscosity of epoxy resin and improve its fluidity.
Adding relatively small amounts can significantly change the viscosity of epoxy resins.

Participation reaction:
Unlike non-reactive diluents, epoxy-reactive diluents can participate in chemical reactions during the curing process and form part of the network structure.
This helps improve the properties of the cured epoxy resin, such as elasticity, corrosion resistance, etc.

No impact or acceleration on cross-linking time:
For some systems (such as aliphatic amine or polyether amine systems), epoxy-reactive diluents will not prolong the cross-linking time and may even accelerate the cross-linking reaction.
This helps shorten curing time and improves production efficiency.

Improve shine:
The epoxy reactive diluent can effectively suppress oil and whitening phenomena on the surface of cured products.
The coating has a higher gloss and a better appearance.

Versatility:
Epoxy-reactive diluents not only have a diluting effect but can also be used as organic synthesis intermediates or industrial additives.
Widely used in construction, automobiles, coatings, papermaking, textiles, electronics, daily chemicals, adhesives, aerospace, and other fields.

shortcoming

Optional:
The choice of epoxy reactive diluent needs to be determined based on the specific epoxy resin system and curing conditions.
Different epoxy resins and curing agents may require different reactive diluents to match.

Cost:
Some high-performance epoxy reactive diluents cost more.
This may increase the production cost of the product.

Storage and transportation:
Epoxy-reactive diluents usually need to be stored in a cool, dry, well-ventilated place.
Unfavorable conditions such as high temperature and humidity also need to be avoided during transportation.

Reactivity:
Epoxy-reactive diluents have high reactivity and require strict control of reaction conditions during the curing process.
Otherwise, problems such as incomplete curing or over-curing may result.

In summary, epoxy-reactive diluents have many advantages, but there are also some disadvantages that need to be noted. It needs to be selected and adjusted according to the specific situation when using it to ensure the quality and performance of the product.
