The document compares different diluents for use with epoxy resins to improve properties like viscosity, glass transition temperature, mechanical strength, and water absorption. It tests various aliphatic and aromatic diluents, reporting their epoxy equivalent weight, viscosity, efficiency when added to an epoxy resin, gel time and pot life, glass transition temperature before and after curing, water absorption, shear strength, tensile strength, elongation, compressive strength, impact strength, and electrical properties. It concludes that 1,4-butane-diol diglycidyl ether is the best aliphatic diluent overall based on its good efficiency, moderately high glass transition temperature of 134属C after curing

14. Conclusions Resorcinol Diglycidyl Ether gives the highest Tg but very poor dilution efficiency. Because of health hazards, it is ruled out. Trimethylol propane triglycidyl ether gives next best Tg. Good mechanical properties as well. If high dilution ratio (~40 phr diluent) is acceptable, it can be recommended. 1,4-butane-diol diglycidyl ether is the best difunctional aliphatic diluent with good efficiency, moderately high Tg (134oC) and best overall mechanical properties. Hence it is ideal for filament winding, pultrusion, casting and encapsulation.
