Grounding, Sealing
An epoxy resin primer is essential for reliable adhesion and provides a secure bonding layer between the substrate and the subsequent epoxy resin coating. Whether on wood, metal, concrete, or plastics – the right epoxy resin primer improves adhesion, ensures even surface wetting, and offers long-lasting protection against moisture and wear. Especially, 2K epoxy resin primers impress with their excellent mechanical and chemical resistance, making them suitable for a variety of applications.
Epoxy resin primer – Optimal adhesion for durable coatings
Why is an epoxy resin primer important?
The right epoxy resin primer is crucial for a stable and durable coating, particularly on smooth or porous substrates. Without an appropriate primer, adhesion problems, moisture absorption, or osmotic damage can occur, significantly reducing the lifespan of the coating. A high-quality 2K epoxy resin primer creates a uniform anchoring layer that prevents moisture penetration and significantly increases the surface's mechanical strength. Especially for demanding materials such as metals, plastics, or concrete, careful pretreatment with the right epoxy resin primer is crucial. This increases resistance to chemical influences, ensures an even surface structure, and minimizes the risk of blistering or cracking in the final product.
Our selection of 2K primers for optimal adhesion
> Epoxy Resin Primer – Perfect foundation for robust coatings
The epoxy resin primer HP-E80FS is a high-quality 2K epoxy resin combination of resin and hardener, which offers excellent adhesion to various substrates due to its low-viscosity formulation. With a processing time of 35 minutes, it ensures even surface wetting and allows reliable bonding of laminating resins, adhesives, and paints. Thanks to its excellent mechanical and chemical resistance, this epoxy resin primer is ideal for wood, concrete, GRP and CFRP components, and many other materials.
> Polyurethane Primer – Adhesion promoter for demanding substrates
The 2K PUR primer HP-UC was specifically developed for use with epoxy resin systems and serves as a powerful adhesion promoter on smooth, non-absorbent substrates. Whether metal, glass, plastic, or tiles – this epoxy resin primer creates a particularly high interlayer adhesion, making it ideal for carbon coatings and laminating work. Its spray-ready formulation allows for easy application with a brush, roller, or spray and is durable, wax-free, and styrene-free.
What benefits does an epoxy resin primer offer?
> Optimal adhesion and protection for various substrates
A high-quality epoxy resin primer significantly improves adhesion properties and enables reliable bonding of epoxy resin systems with a wide range of materials. While porous substrates like wood or concrete are deeply penetrated and stabilized by the low-viscosity formulation, specialized adhesion promoters ensure reliable adhesion on smooth surfaces like glass, plastics, or metals. Another advantage is the corrosion protection an epoxy resin primer provides on metal surfaces, preventing oxidation and forming a resilient protective layer that withstands mechanical and chemical stresses. Additionally, an epoxy resin primer can act as an osmotic barrier, keeping moisture away from the material and ensuring long-term stability.
> Versatile processing options and quick reworkability
Modern 2K epoxy resin primers can be processed flexibly – whether by brushing, rolling, or spraying. Many systems are formulated to be quickly overcoated, allowing additional layers of laminating resins, adhesives, or paints to be applied shortly after. This saves time and allows for efficient processing in industrial or craft applications. Another advantage is the non-stick curing, which ensures clean further processing. Thanks to the wax-free and styrene-free formulation of some systems, these can be easily combined with other epoxy, polyurethane, or polyester resins without causing undesirable interactions.
Where is epoxy resin primer used?
The applications of an epoxy resin primer are highly versatile. It is used in areas such as boat building, the automotive industry, construction, and aerospace to ensure lasting adhesion and long-term protection. Especially when coating CFRP and GRP components, multiplex boards, metals, or mineral substrates, the right epoxy resin primer improves surface adhesion and significantly increases the longevity of the entire coating. It also enables the use of various coating systems, including acrylic, alkyd, epoxy, and polyurethane paints, offering a broad range of further processing options. Those looking to buy a high-performance 2K epoxy resin primer will find a variety of high-quality products tailored to the needs of professional applications. By carefully choosing a suitable epoxy resin primer, the long-term durability, chemical resistance, and mechanical strength of coatings can be significantly enhanced.
