What TUE is
TUE is the premium epoxy in the ResinTech range. It is formulated to cure clear and glossy, to be field-pigmented where a coloured coat is required, and to be used at anything from an 8 mil primer to a 250 mil controlled self-levelling build.
It is more resistant to UV than an ordinary epoxy and resists yellowing better than standard epoxy, but it is not a UV-stable aliphatic coating. Where a floor sees permanent, unprotected sunlight, the TDS calls for an HPP or CRU topcoat over it.
In ResinTech traffic coating systems, TUE is the optional premium reinforcement / build layer and may be substituted for CBE where a premium epoxy is preferred.

Performance properties
Typical values at 23 °C and 50 % RH unless noted, as published in TDS-TUE-1.0. Not a guarantee of performance.
| Property | Typical value | Method / note |
|---|---|---|
| Bond strength to concrete | 370 psi | ASTM D4541 — typically concrete cohesive failure |
| Tensile strength | 6,500 psi | ASTM D412 / D638 reporting class |
| Elongation | 6 % | ASTM D412 / D638 reporting class |
| Abrasion resistance | 35 mg loss | ASTM D4060, CS-17 wheel, 1000 g, 1000 cycles |
| Shore hardness | 80 D | ASTM D2240 |
| Tack-free time | 10 h | ASTM D1640 at 15 mils |
| Drying time | 20 h at 15 mils | ASTM D1640, 24 °C / 50 % RH |
| UV resistance | UV-resistant epoxy | Not a UV-stable aliphatic topcoat |
Working time, recoat and cure
| Temperature | Pot life | Recoat window | Light foot traffic | Full cure |
|---|---|---|---|---|
| 10 °C | 60–75 min | 18–24 h | 36–48 h | ~10 days |
| 21 °C | 40–60 min | 14–18 h | ~24 h | ~7 days |
| 30 °C | 20–30 min | 8–12 h | 12–18 h | 4–5 days |
If the surface is hard, glossy or outside the recoat window, sand or abrade, vacuum and clean before recoating. Large mixed volumes shorten pot life and generate heat.
Coverage and film build
| Use | Film build | Typical coverage |
|---|---|---|
| Primer / base coat | 8–10 mils | 200–160 ft²/US gal |
| Top coat | 8–16 mils | Withheld — see note |
| Broadcast receiver | 10–25 mils before broadcast | Withheld — see note |
| Self-levelling build coat | 40–250 mils in controlled pours | By design and mass control |
Coverage figures under confirmation. Typical coverage for the top-coat and broadcast-receiver rows is withheld while the figures published in TDS-TUE-1.0 are confirmed with ResinTech: their basis (wet or dry film, volume solids) is not stated and they do not reconcile with the film-build ranges shown. The film-build ranges are unchanged. Confirm yield by mock-up.
Theoretical values per US gallon at 23 °C / 50 % RH. A 15 L kit is approximately 4.0 US gal. Actual coverage varies with profile, porosity, film build and method.
Application conditions
| Condition | Requirement |
|---|---|
| Substrate temperature | 10–30 °C |
| Ambient temperature | 10–32 °C |
| Relative humidity | Maximum 85 % recommended |
| Dew point | Substrate at least 3 °C above dew point |
| Concrete moisture | Dry concrete; typical screening limit 4 % Tramex or 85 % RH by ASTM F2170 |
| Concrete age | Normally 28 days unless the designer approves earlier work |
| Minimum concrete strength | 3,600 psi compressive; 220 psi tensile pull-off |
Limitations
- UV-resistant, not UV-stable: under prolonged unprotected UV it can amber or lose gloss. Topcoat with HPP or CRU for permanent exterior exposure.
- Not a crack-bridging membrane; not for active cracks, moving joints or structural movement.
- Not a waterproofing membrane or moisture-vapour mitigation system.
- Deep pours (up to 2 in.) are for experienced installers only, with a mock-up and heat-control plan.
- Do not apply to wet, frozen, contaminated, dusty or condensing substrates.
- Cures glossy with a slight satin character. Where a mirror-like super high-gloss finish is required, ResinTech recommends CBE.
- For severe chemical service, protect with a CRU topcoat.

Questions and answers
Is TUE UV-stable?
No. TUE is a UV-resistant epoxy — it resists yellowing better than a standard epoxy — but it is not a UV-stable aliphatic system. For permanent unprotected UV exposure the TDS calls for an HPP or CRU topcoat over it.
What is the mix ratio and kit size?
2 : 1 by volume. A kit is Part A 10 L plus Part B 5 L, giving 15 L (about 4.0 US gal) of mixed material.
Can TUE be used as a self-levelling build coat?
Yes, at 40–250 mils in controlled pours by experienced installers. Mass and temperature must be controlled to limit exotherm.
How does TUE differ from CBE?
CBE is the high-bond standard epoxy (420 psi bond to concrete on the TDS) used as primer, bond coat and broadcast binder; TUE is the premium clear epoxy with better UV resistance and a glossy, slightly satin finish. TUE may be substituted for CBE in ResinTech traffic systems.
