HIGH BUILD EPOXY REDUCER

What is ALEXSEAL R3040 High Build Epoxy Reducer and why choose it

ALEXSEAL R3040 High Build Epoxy Reducer is a halogen-free mixture of organic solvents designed to reduce the viscosity of compatible ALEXSEAL epoxy systems, such as ALEXSEAL Super Build 302. It is formulated for industrial serial painting and provides controlled thinning to optimise spray application, flow and film build. The product is a clear, colourless/transparent, highly flammable liquid with a characteristic odour and is intended for professional use in environments where precise application properties and reliable film formation are required.

Main characteristics

• Purpose-formulated epoxy reducer – specified in the Super Build 302 technical data sheet as the dedicated reducer for ALEXSEAL high build epoxy primers.
• Optimised for spray application – enables adjustment of viscosity for conventional, HVLP and airless spray systems as indicated in ALEXSEAL Super Build 302 mixing examples (10–25% by volume depending on application method).
• High solids compatibility – supports very high dry film thickness (up to 500 µm / 20 mils DFT for Super Build 302 systems) when used according to the specified mixing ratios.
• Halogen-free solvent blend – chemical nature specified as a halogen-free mixture of organic solvents.
• Highly flammable liquid – classified as Flammable Liquid Category 2 with flash point of 6 °C (ISO 13736), requiring strict handling and storage controls.
• Health hazard classification – causes serious eye irritation, may cause drowsiness or dizziness, and repeated exposure may cause skin dryness or cracking.
• Industrial-grade formulation – intended for industrial serial painting processes where professional safety and environmental controls are in place.

Section 8 – Measures of personal protection

Engineering controls

• Provide adequate ventilation through local exhaust and general extraction.
• If ventilation is insufficient to keep solvent vapour concentrations below occupational exposure limits, suitable respiratory protection must be worn.

Personal protective equipment

Eye and face protection

• Wear safety goggles to protect against solvent splashes.

Hand protection

• Use chemical-resistant protective gloves tested in compliance with EN 374.
• Recommended materials for short-term contact (splash protection): nitrile rubber or neoprene.
• Minimum material thickness: > 0.4 mm.
• Breakthrough time: > 480 min.
• Always verify glove suitability for the specific workstation (mechanical resistance, product compatibility, antistatic properties) and follow glove manufacturer instructions for use, storage, care and replacement.
• Replace protective gloves immediately if damaged or worn. Preventive skin protection (skin protection cream) is recommended and contaminated skin should be washed immediately.

Skin and body protection

• Depending on the probability of dangerous or explosive atmospheres, wear suitable protective clothing.
• In the Spanish data sheet, anti-static clothing of natural fibres (cotton) or heat-resistant synthetic fibres is recommended for related systems.

Respiratory protection

• If solvent concentration exceeds workplace air limits, a suitable breathing apparatus approved for this purpose must be worn.
• Use at least a half-mask model with cartridge or an air-fed respirator.
• When operators have to work inside spray booths, they should wear a compressed air-fed respirator during spraying until particulate and solvent vapour concentrations are below exposure limits.

General protective measures

• Do not eat, drink or smoke during use.
• Avoid contact with skin, eyes and clothing.
• Avoid inhalation of sanding dust, spray mist and solvent vapours.
