ResinTech CRU Chemical-Resistant Urethane — Premium Protective Finish Coat

Two-Component, High-Solids Aliphatic Polyurethane Finish Coat — Maximum Chemical, Abrasion & UV Protection | Brand: ResinTech | 6 L kit

ResinTech CRU is a premium aliphatic polyurethane finish coat used as the final protective layer over compatible epoxy, polyaspartic, broadcast and traffic coating assemblies. It is for projects that need more than a standard topcoat: better long-term wear resistance, stronger chemical protection, excellent UV stability and a hard, cleanable finish. CRU is the thin durability layer of the ResinTech line — the final armour coat, not the build coat, membrane or fast-track coat. Confirm chemical exposure, surface preparation, system compatibility and cure schedule against the current ResinTech TDS, SDS and project specification before use.

A ResinTech alternative to Tremco Vulkem 950NF & 951NF
ResinTech CRU is stocked in North Vancouver and used in the same two-component polyurethane topcoat and chemical-resistant wearing-course applications. Product chemistry and system build differ between manufacturers — confirm suitability against the current ResinTech TDS before substituting. Vulkem is a registered trademark of Tremco. Used for identification and comparison only; no affiliation or endorsement implied.
Two critical application rules:
  1. Thin film only. Apply at 3–6 mils (recommended); never exceed 20 mils total. CRU is a thin finish coat and will fail in cure, appearance and adhesion above this thickness.
  2. Not recoatable once cured. CRU is the final coat. If any material must go over cured CRU, the surface must be mechanically abraded (sanded) first for a physical bond only — cured CRU will not chemically recoat.
Field Details
Brand ResinTech
Product Code CRU
Product Type Two-component, high-solids aliphatic polyurethane finish coat
Kit / Pack Size 6 L kit — Part A 4 L + Part B 2 L (1.6 US gal mixed), pre-proportioned 2:1 by volume
Mix Ratio Pre-proportioned A + B kit as supplied — do not alter the ratio
Colour / Finish Clear or field-pigmented; smooth, or slip-resistant when broadcast media is specified
System Role Premium protective finish — the final armour topcoat in ResinTech systems
Where CRU sits in the system: CRU is the final armour coat of the ResinTech system — prime and bond with CBE, build with TUE, fast-finish with HPP, and protect it all with CRU — the strongest, most chemical-, abrasion- and UV-resistant topcoat in the line. Apply thin (3–6 mils) over compatible cured coatings; it is the final, non-recoatable layer. Confirm the system specification against the current ResinTech documentation.

Best-Use Applications

Confirm all applications against the current ResinTech TDS before specifying.

  • Premium topcoat for parking decks, ramps, drive lanes, turning zones and service areas
  • Final protective coat over sand, quartz, flake and reinforced traffic coating systems
  • Commercial, institutional, warehouse, mechanical room, automotive and light industrial floors
  • Exterior or interior floors where UV stability, abrasion resistance and cleanability matter
  • Balconies, podium decks, walkways, corridors and amenity areas over compatible base systems
  • Food and beverage, service, utility and maintenance spaces exposed to routine cleaning chemicals
  • Protective clear or pigmented upgrade over HPP, TUE, CBE or other compatible cured coatings
  • Parkade and strata restoration projects where long-term durability is valued over fastest cure

Performance Properties

Typical values from the ResinTech CRU TDS. Actual results depend on substrate, base coat, preparation, mixing, film build and conditions — confirm against the current TDS.

Property Typical Value Test Method / Note

Tensile Strength 5,800 psi ASTM D412
Elongation 4% Hard protective film; not a flexible membrane
Abrasion Resistance 20 mg loss (best in the line) ASTM D4060, CS-17 wheel, 1000 g, 1000 cycles

Chemical Resistance Superb Premium chemical-resistant finish coat in the ResinTech line
Return-to-Service Speed Standard Prioritizes long-term protection over fast cure

Working Time, Recoat & Cure

CRU is a premium protection coat, not the fastest-return material — use HPP when speed is the priority, CRU when durability is. Confirm against the current TDS.

Condition Typical Value Practical Note
Recoat / Overcoat Window 4–6 hours (wet only) Apply any second pass within this window. Once cured, abrade mechanically first.
Light Foot Traffic About 24 hours Protect from water, dust and early abuse
Vehicle Traffic About 72 hours Allow longer in cool, damp or low-airflow conditions
Full Cure About 7 days Delay aggressive cleaning and chemical exposure until full cure
Rain / Moisture Protection Protect during early cure Exterior work must be staged around weather and dew point

Coverage & Film Build

Theoretical coverage per US gallon (6 L kit ≈ 1.6 US gal). Recommended film 3–6 mils; never exceed 20 mils total. Confirm against the current TDS.

Maximum-Protection Topcoat 5–10 mils 530–265 ft²/US gal
Clear Decorative Finish 4–6 mils Depends on flake / quartz profile and desired texture / gloss

Application Notes

Always confirm application requirements against the current TDS, SDS and project specification before use.

Surface Preparation

Apply only to clean, dry, sound substrates or compatible cured coatings. Remove dust, laitance, oil, grease, curing compounds, sealers, loose broadcast and bond breakers. Existing coatings must be sound, compatible and properly abraded — do not apply over glossy, soft, unknown or poorly bonded coatings. Mechanically prepare concrete to the profile required by the base system; for recoating cured resin, abrade uniformly to remove gloss. Vacuum thoroughly before coating. Moving joints must remain functional and be sealed separately with appropriate joint sealant. Confirm against the current TDS.

Mixing

Condition material to application temperature before use. Pre-mix each component separately; add compatible pigment to Part A where a pigmented finish is required. Combine the supplied Part A and Part B in the correct pre-proportioned ratio and mix mechanically for 2–3 minutes at low speed until uniform. Scrape sides and bottom of the pail and avoid whipping air into the coating. Do not thin with solvents. Apply promptly after mixing and maintain a wet edge. Confirm against the current TDS.

Application & Overcoating

Apply by high-quality roller, squeegee and backroll, brush for details, or spray where appropriate; maintain an even film. Apply at 3–6 mils (recommended) and do not exceed 20 mils total — excessive thickness causes cure failure, blush and adhesion loss. CRU is not recoatable after cure: sand / abrade the cured surface uniformly to achieve a mechanical bond before applying any subsequent material. For slip resistance, use specified silica sand, quartz, aluminum oxide or approved traction media. Apply clear coats thin and uniform over decorative systems, avoiding puddles that can alter gloss or cure. For pigmented coats, use consistent batching, backroll direction and film thickness; mock-ups are recommended for appearance-critical work. Protect fresh coating from rain, condensation, dust, foot traffic, tires and turning stress until sufficiently cured. Confirm against the current TDS.

Limitations
  • Do not exceed 20 mils total film thickness — CRU is a thin finish coat (3–6 mils recommended) and will fail in cure, appearance and adhesion above this limit.
  • Not recoatable once cured — any subsequent coat or repair requires mechanical abrasion (sanding) of the cured surface for a physical bond only.
  • CRU is a finish coat — not a primer, build coat or crack-bridging membrane.
  • Do not apply to wet, frozen, dusty, contaminated or condensing substrates.
  • Do not apply over unknown or incompatible coatings without adhesion testing and approval.
  • Slip resistance depends on aggregate type, broadcast rate, film thickness and maintenance — approve texture by mock-up.
  • Chemical resistance varies by concentration, temperature, exposure time and housekeeping — test severe exposures before use.
