SEAJET THINNER U

What is SEAJET THINNER U and why choose it?

SEAJET THINNER U is an alkyd thinner designed for use with most alkyd-based marine and protective coatings. Formulated with C9–C11 hydrocarbons, it provides controlled dilution, helping to optimise application properties such as flow, levelling and spray atomisation. It is especially recommended for specific Seajet topcoats, varnishes and primers, ensuring product compatibility and consistent performance within the system.

Main features

• System-compatible: Recommended for Seajet 122 Brilliance, Seajet 120 Varnish and Seajet 012 Universal Primer.
• Optimised application: Suitable for spray and conventional application where thinning is required (see product technical data sheets for exact addition levels).
• High solvent strength: Based on hydrocarbons C9–C11 (n-alkanes, iso-alkanes, cyclic, <2% aromatics).
• Clear liquid: Colourless, with a typical petroleum-like odour.
• Fast-drying support: Boiling range from approx. 155°C helps promote proper film formation of compatible coatings.

Section 8 – Individual protection measures

Engineering controls

• Provide adequate general and local exhaust ventilation to keep solvent vapour and particulates below occupational exposure limits.
• During spraying in spray booths, ventilation alone may be insufficient; additional respiratory protection is required.

Respiratory protection

• If workers may be exposed above exposure limits, use a respirator in accordance with EN 140 fitted with a combined particulate and vapour filter to EN14387 with an assigned protection factor of at least 10 (e.g. A2P3).
• When working inside spray booths during application, use a compressed air-fed respirator until particulate and solvent vapour concentrations are below exposure limits.

Hand protection

There is no single glove material that provides unlimited resistance. For repeated or prolonged contact, use chemical-resistant gloves tested to EN 374. Examples of suitable materials and minimum thicknesses mentioned in the safety data sheet include:

• High protection (permeation breakthrough > 480 min):
  • Polyethylene (PE) gloves, 0.062 mm.
  • PVA gloves, 0.2–0.3 mm.
  • Butyl/Viton gloves, 0.70 mm.
• Medium to high protection (60–240 min):
  • Polyethylene (PE) gloves, 0.062 mm.
  • PVA gloves, 0.2–0.3 mm.
  • Butyl/Viton gloves, 0.70 mm.
  • Neoprene gloves, < 0.4 mm.
  • Nitrile gloves, 0.175 mm.
• Not suitable (breakthrough < 10 min, non-exhaustive):
  • Natural rubber gloves, 0.75 mm.
  • Some neoprene gloves, 0.13 mm.
  • Butyl gloves, 0.50 mm.

Nitrile gloves offer good protection during spray application. Viton gloves are suitable for intense solvent contact such as immersion. Use PE gloves as under-gloves in high-exposure situations or where chemical properties are unknown. Replace gloves regularly and immediately if damaged.

Eye and face protection

• Use safety eyewear tested according to EN 166, designed to protect against liquid splashes.

Skin and body protection

• Wear anti-static clothing made from natural fibres or high-temperature resistant synthetic fibres.

Environmental exposure controls

• Do not allow the product to enter drains or watercourses.
