Epoxy Diluents

Application:
at – 4023rd pge is light yellow liquid mono-epoxide compatible with modified and non-modified dgeba
epoxy resins in all proportions etc.
Typical properties
 viscosity hoppler 6 - 8 mpa.s. @ 25 c
 appearance visual light yellow, clear liquid
 epoxy value 5.9 - 6.3 eq. kg.
 refractive index 1.528 - 1.330 @ 25 c
 storage stability up to 12 months in original container.
Addition of reactive diluent to an epoxy resin imparts the following advantages:
 viscosity reduction without increasing volatiles.
 higher filler loadings, which in turns results in cost reduction. Secondary benefits of the
higher filler loadings, such as higher compressive strength, lower co-efficient of
expansion; lower exotherm and lower shrinkage are also obtained.
 increased pot life of resin - hardener mixture without increasing total cure time.
Method of incorporation
the required proportion of reactive diluent not exceeding 20 parts per hundred, is first added to the
epoxy resin and mixed thoroughly to give a homogeneous mixture. Hardener is then added and remixed.
The epoxy value of the diluents must be considered to calculate the correct proportion of hardener
required. For solid hardeners the mixture of epoxy resin and diluents is heated prior to the addition of
hardener as with conventional epoxy resins.
