What is PU Paint?

PU Paint, or Polyurethane paint, is a hard, stretchable polymer pigment coating that is used to surface-finish and protect wooden and metallic surfaces. It provides a smooth and luxurious finish, and is available in matte and high gloss textures. The PU coat protects furniture from moisture, scratches, dust and makes it very durable; a PU coating looks exactly the same for as long as 15 years.

Some types of PU Paint

1. 1K - PU Paint

1K-PU is a solvent-borne PU-based primer with a single component. The solvent evaporates after treatment, and the residual chemical crosslinks by absorbing moisture from the air and, in the case of a concrete surface, from the surface. 1K-PU is developed to soften and prepare old coatings before over-treating them with new layers. It is also an excellent primer for blast steel surfaces not susceptible to high-temperature submersion applications. 

It’s suitable for both outdoor and indoor decoration. It dries and cures quickly, resulting in minimal downtime and related losses. It’s just as simple to apply as epoxy, but PU has a quicker return-to-service time.

Advantages:

• Good adhesion
• Good flexural strength
• High hardness
• High solid content
• Not fade
• Weather resistant, anti-yellowing
• Beautiful colors, high gloss
• Easy to use.

Disadvantages:

• No scratch resistance
• Not resistant to solvents

1. Vinyl paint

Vinyl paint is a paint specially manufactured for industrial paint lines. Paint has quick drying properties, overcoming the characteristics of conventional water-based paints. Mainly vinyl paint is used as a primer and additional coating on wood or metal, ceramic surfaces.

Advantages:

• Good adhesion
• Good flexural strength
• Transparent paint film
• Dry fast
• Easy to use

Disadvantages:
