PU SPRAY THINNER 2 COMPONENTS

What is PU SPRAY THINNER 2 COMPONENTS and why choose it?

PU SPRAY THINNER 2 COMPONENTS by Epifanes is a specially formulated poly-urethane spray thinner designed as a solvent mixture for professional applications. It is intended to dilute compatible two-component polyurethane products for spray application, helping to achieve the correct spraying viscosity and a smooth, even finish. With a very low flash point and high solvent strength, it is suited for demanding spray environments where fast drying and fine atomization are required.

Main features

• Professional spray thinner – Epifanes Poly-urethane Spraythinner formulated for use in spray applications of polyurethane systems.
• High solvent power – based on a blend of butanone, 2-methoxy-1-methylethyl acetate, n-butyl acetate, xylene and ethylbenzene for effective viscosity adjustment.
• Highly flammable liquid – classified as Flam. Liq. 2 (H225), requiring careful handling and storage.
• 100% solvent / VOC content – contains 100% organic solvents with a VOC content of 883.3 g/l (7.37 lb/gal).
• Clear fluid with characteristic odor – easy to mix and visually control in coating systems.

FAQ – PU SPRAY THINNER 2 COMPONENTS

1. 1. What is PU SPRAY THINNER 2 COMPONENTS used for?

   It is a poly-urethane spray thinner, supplied as a solvent mixture, intended to dilute compatible polyurethane products for spray application. Consultar ficha técnica del fabricante.

2. 2. Is this thinner suitable for brush or roller application?

   The safety data sheet only specifies use as a spray thinner. Consultar ficha técnica del fabricante.

3. 3. Why must this product be used only in well-ventilated areas?

   The product is classified as highly flammable (Flam. Liq. 2, H225) and may cause drowsiness or dizziness (STOT SE 3, H336). Adequate ventilation reduces the concentration of vapors and lowers the risk of inhalation exposure and explosive mixtures.

4. 4. Does PU SPRAY THINNER 2 COMPONENTS contain VOCs?

   Yes. It contains 100% organic solvents with a VOC content of 883.3 g/l (7.37 lb/gal).

5. 5. Can this product cause health issues with prolonged exposure?

   The mixture contains components such as xylene and ethylbenzene and is classified as STOT RE 2 (H373 – may cause damage to organs through prolonged or repeated exposure) and Carc. 2 (H351 – suspected of causing cancer).

6. 6. What should I do if the product gets into my eyes?

   Rinse the opened eye for several minutes under running water. If symptoms persist, consult a doctor.

7. 7. How should spills be handled?

   Ensure adequate ventilation, keep unprotected persons away, prevent entry into sewers or surface water and absorb with suitable liquid-binding material such as sand, diatomite, universal binders or sawdust. Dispose of contaminated material as waste according to local regulations.

8. 8. How should empty containers be disposed of?

   Packaging must not be disposed of with household garbage. Disposal of uncleaned packaging must follow official regulations.

9. 9. Is the product hazardous for water?

   Yes. It is classified as water hazard class 2 (hazardous for water). Do not allow it to reach ground water, water courses or sewage systems.

10. 10. At what temperature should the product be stored?

    The SDS specifies storage in a cool, dry place, in tightly sealed original containers. Exact storage temperature ranges should be confirmed with the manufacturer. Consultar ficha técnica del fabricante.
