Site-grade acetone for tool cleaning, surface degreasing, and wipe-downs across the RORR GRP system. High purity, clear and colourless, and made to consistent spec — so it flashes off clean and leaves no residue when used correctly. Conforms to BS 509.

Why roofers pick it

• High purity: ≥ 99.7% acetone for reliable cleaning performance.
• Low residue: Evaporates clean; residue on evaporation ≤ 0.001% — ideal before laminating or topcoating.
• Consistent spec: Boiling range tightly controlled (56.2 °C, max 1 °C spread) and specific gravity 0.790–0.793 @ 20/4 °C.
• Ready for UK conditions: Clear/colourless, Hazen ≤ 5, miscible in water (use dry rags for best results).

Typical uses

• Clean rollers, brushes, consolidators after using RORR Roofing Resin or RORR Topcoat.
• Surface degrease cured GRP before sanding/overcoating (wipe on, wipe off with a clean cloth).
• Spill/edge tidy-up while laminating (use sparingly; don’t flood the laminate).

Do not thin RORR resins or topcoats with acetone — it’s for cleaning and prep, not for altering product formulation.

Sizes

• 1 L can — handy for small jobs, van kits, and detail work.
• 5 L can — cost-effective for daily shop/site use.

Safety & handling (read this bit)

• Highly flammable liquid and vapour. Keep away from heat, sparks, open flames; use explosion-proof kit and non-sparking tools. Ground/bond containers.
• Irritation & dizziness risk. Causes serious eye irritation; may cause drowsiness/dizziness; repeated exposure may dry/crack skin. Use in well-ventilated areas and wear suitable PPE (gloves/eye protection).
• First aid (summary): If on skin/hair, remove contaminated clothing and rinse. If inhaled, move to fresh air. If in eyes, rinse cautiously and remove lenses. If swallowed and unwell, seek medical advice.
• Storage: Keep tightly closed, cool, and locked up in a well-ventilated place. Dispose in line with national regulations.

FAQs

Can I use acetone to thin RORR resin or topcoat?
No — it’s a cleaner/prep solvent. Thinning can compromise cure and finish.

Will it leave a film before I topcoat?
It’s specified for very low residue on evaporation. Wipe on and dry-wipe off with clean cloths.

Is it safe to use indoors?
Only with good ventilation and proper PPE. It’s highly flammable — manage ignition sources.
