What is HS Clear Coat Activator Medium and why choose it?
HS Clear Coat Activator Medium (ALEXSEAL R5561) is a halogen-free organic solvent mixture formulated as the medium activator for the ALEXSEAL HS Clear Coat system. Designed for professional, industrial serial painting, it acts as an activated reducer that is mixed in a fixed ratio with ALEXSEAL HS Clear Coat (H0150) and Clear Coat Converter (C5067). The result is an optimized sprayable clearcoat with controlled viscosity, reliable curing and a high-gloss, wet-look finish suitable for demanding yacht and industrial applications.

Section 8 – Personal protective measures
Exposure controls
- Engineering controls: Provide adequate ventilation. Preferably use local exhaust and good general extraction to maintain solvent vapour and aerosol concentrations below occupational exposure limits. If ventilation is insufficient, use suitable respiratory protection.
Personal protective equipment
- Eye protection: Safety goggles to protect against solvent splashes.
- Hand protection: Chemical-resistant protective gloves tested according to EN 374. Recommended materials for short-term contact include nitrile rubber or neoprene with a thickness > 0.4 mm and breakthrough time > 480 minutes. Gloves must be checked for workplace suitability and replaced immediately if damaged or worn.
- Skin and body protection: Antistatic clothing made of natural fibre or high-temperature-resistant synthetic fibre. Wash all body parts after contact; avoid permanent use of protective gloves by designing operations accordingly.
- Respiratory protection: If exposure may exceed limits, use appropriate certified respirators, such as a half-mask with cartridge or air-fed equipment. When working inside spray booths where ventilation may not control particulates and vapours adequately, use a compressed air-fed respirator during spraying until concentrations fall below exposure limits.
- General protective measures: Do not eat, drink or smoke during work. Avoid contact with skin, eyes and clothing. Avoid inhalation of vapours, particulates, sanding dust and spray mist.
