Products information
Polyurethane (PU) Primer is a high-performance undercoat or base coat used to prepare various surfaces (such as wood, concrete, plaster, or metal) before applying a polyurethane top coat. This primer is typically a one-component (single-component) or two-component (two-pack) product that cures through a reaction with air humidity or a dedicated hardener.
Key Features & Benefits (Tính năng và lợi ích chính)
- Superior Adhesion: Provides excellent bonding between the substrate and the top coat, preventing delamination and ensuring a long-lasting finish.
- Sealing and Penetration: Effectively penetrates porous surfaces like concrete or wood to seal them, strengthening the substrate structure and protecting against moisture absorption.
- Surface Preparation/Filling: Helps fill minor imperfections and creates a smooth, non-porous base for the final paint layer, which enhances the aesthetic appearance of the top coat.
- Durability and Resistance: The cured film offers good resistance to water, abrasion, and certain chemicals, enhancing the overall durability of the coating system.
- Fast Drying/Curing: Many PU primers are fast-curing, allowing for quick application of subsequent layers and reducing project downtime.
- Versatility: Can be applied to a wide range of surfaces, including dry and damp concrete, wood, gypsum, and various metals.
Typical Applications (Ứng dụng tiêu biểu)
PU Primers are widely used in:
- Wood finishing: As a sanding sealer or primer for furniture and architectural woodwork.
- Flooring/Waterproofing: As a primer for polyurethane floor coatings or liquid waterproofing membranes on concrete substrates.
- Automotive/Marine: In two-component systems for use on gelcoat, existing epoxy systems, or metal surfaces
