- Properties
Due to their structure, reactive diluents have low viscosity. ARALDITE® DY 31 is a polymer.
The incorporation of ARALDITE® DY 31 has the following effects:
- A reduction of viscosity when used in a Standard Epoxy resin
- High reactivity is maintained (potentially increased)
- Practically no reduction of hardness
- A slight decrease of warm water resistance
- A slight reduction of acid resistance
- High resistance to solvents and ammonia
- The best diluent for Glass Transition retention
The reactive diluent in the resin component should not exceed 20%.

- Application Information
Unmodified bisphenol-A and bisphenol-A/F epoxy resins - such as ARALDITE® GY 250, GY260, GY 261, GY 266, PY 302-2 or PY 304 - are mixed with ARALDITE® DY 31 to produce low-viscosity epoxy resins for solvent-free coatings, flooring compounds and Adhesive/mastics.
ARALDITE® DY 31 should preferably be used when reactivity, hardness and resistance to warm water, solvents and ammonia are to be maintained.- 100% Solids chemical resistant coatings
- Concrete crack repair
- Coatings for containment areas
- High-performance adhesives

Comparison of ARALDITE® DY 31 with ARALDITE® DY-T: Mechanical properties when fully cured with ARADUR® 20315. Resin + hardener mixed at stoichiometry Cure profile: 1 h at 80°C + 1 h at 120°C + 1 h at 150°C Epoxy content of ARALDITE® DY 31 being higher than ARALDITE® DY-T leads to a different ratio between resin and hardener leading to a Higher Tg and a lower elongation at break. Other parameters are very similar.

- Technical Graphs
The larger epoxy content of ARALDITE® DY-31 vs. ARALDITE® DY-T leads to a different ratio between resin and hardener resulting in a higher glass transition temperature and a lower elongation at break.
