VOSSCHEMIE Polyurethane-Thinner

A solvent-based, single-component polyurethane resin that is excellent as a bonding primer for laminates with epoxy or polyester coatings. VOSSCHEMIE PAINT SYSTEM G4 Extra cures by releasing solvents and cross-links by absorbing moisture from the air and the substrate. This creates a wear-resistant film with high impact strength.As a binder for wood flour, G4 Extra can also be used to make wood filler for filling chips and wind cracks. It is also suitable for durable sealing of dark woods (e.g. mahogany). The coating has a yellowish-transparent tint that is intensified under UV exposure. Improved UV protection is provided by VOSSCHEMIE polyurethane varnish G8 SUPER. Not suitable for use in interior areas (e.g. cabin).Technical DataSubstrates: Wood, concrete, steel, GRPSubsequent coating: 1K or 2K PUR coatings, GRP laminatesCoverage: approx. 0.1 l/m² (non-absorbent substrates), 0.2–0.25 l/m² (absorbent substrates)Thinning: noneApplication method: Brush, lambskin roller, spray gun (professional users, only with respiratory protection!)Drying times at 20 °C: recoatable with itself: 2–4 hrs (as soon as substrate is tack-free), max. 12 hrs. GRP: 0.5–4 hrs (tacky)Note: Product contains hazardous chemicals according to REACH regulation. We recommend processing only by commercial users. Contains isocyanates. may cause allergic reactions.

VOSSCHEMIE G8 SUPER is a one-component polyurethane clear coat with high resistance to chemicals, cleaners, and weathering. The solvent-based coating cures through humidity, remains nearly non-yellowing, and is suitable for many absorbent substrates such as wood, metal, and solvent-resistant plastics. Due to its formulation, the product does not contain additional UV absorbers and is not suitable for use in living areas.Application: G8 SUPER is applied with a brush or spray gun. The substrate must be clean, dry, and free of grease; solid wood must not exceed a maximum wood moisture content of 15%. For priming on porous substrates, dilution with a maximum of 50% polyurethane thinner is recommended. The application amount per layer should not exceed 250 ml/m². For a durable surface film, at least three undiluted coats are required. Recoating can be done after 2–4 h or alternatively after intermediate sanding.Technical DataApplication area: Clear coat for wood, metal, plastics, and epoxy laminatesSubstrate: Clean, dry, grease-free; solid wood max. 15% wood moistureCoverage: approx. 200–300 ml/m² per coatThinning: Max. 50% polyurethane thinner recommended for primingApplication method: Brushing or sprayingDrying times (at 20 °C): Dust dry after 2–4 h, recoatable within 24 hCuring time: Fully cured after at least 7 daysNote: Product contains hazardous chemicals according to the REACH regulation. We recommend use only by professional users. Contains isocyanates. May cause allergic reactions. As of August 24, 2023, appropriate training must be completed before industrial or professional use (EU REACH regulation).
