Low Thickness Transparent Epoxy Resin

Low Thickness Epoxy Resin for Pouring Over a Surface

Simply mix and pour this transparent resin over a flat or textured surface to achieve a smooth, high gloss finish that adds depth and character. At an application thickness of just 1-2 mm, the Low Thickness resin self-levels to create a flat, durable surface that can be sanded and polished to a luminous shine.

When compared to lacquers used as a transparent topcoats, this epoxy resin enhances the surface with a lustrous glass-like appearance for more visual depth with higher durability. Apply this resin over any painted surface or over one of our Special Effect paints for a truly unique finish.

With Cromas Paints extensive experience in producing special effect paints, our scientists have developed these professional resins for commercial and designer applications. Many of the other available resins are intended for a DIY customer.

The Cromas resins were developed to feature these professional characteristics:

  • A Low Viscosity and is Balanced – the material is self-levelling at low thickness
  • A High Resistance to Carbonation – this is the reaction between the resin’s hardener with the air and humidity that can cause defects in the surface
  • Resistant to UV rays, Low Yellowing, and for interior use only
  • Calculated Mass Effect – the low temperature rise of the curing resin – tested on common furniture surfaces
  • Highly Durable Finish that can be sanded and polished for a perfectly smooth surface

Application Information

The main use for the Low Thickness resin is for pouring over level surfaces. This product is known as a balanced or self-levelling resin meaning that if your surface is level, then the dried surface will have equal thickness in all areas.

Once the resin is fully hardened it becomes a flat, high-gloss surface that is super durable and offers a higher resistance than common lacquers. An application of 1 to 2 mm in thickness can be poured over a smooth or textured surface without the need for a frame or mould. Then it is sanded a polished to achieve a gloss lustre.

For a surface with a little higher thickness, it is possible to make a simple frame with adhesive tape. This border will contain the poured resin to create a higher thickness surface that can be shaped, sanded and polished. Taking it one step further, you can make a surface between 5 to 10 mm thick. This should only be used on a smaller surface area that has a total resin mass below 2 kg. If you need a higher thickness, we suggest to use the Medium Thickness Epoxy Resin.

If the resin is poured over untreated wood, it is necessary to seal or insulate the material first. This is to prevent any humidity or moisture from escaping into the resin causing bubbles during the curing process. To seal a surface, apply several layers of the Cromas epoxy resin or sealer. We suggest to use a high-viscosity insulating product that is applied with a brush or spatula.

This resin has been studied for low thickness applications with cure times of 24-48 hours at a room temperature of 20-25°C. When working with this thickness the curing temperature rise of the resin is moderate. The recommended temperature during the working and hardening time is at least 20° C or higher. At lower temperatures, the curing time increases and some imperfections may appear on the surface.

Besides room temperature, humidity is also a crucial factor. Make sure the surface material and the working area are dry and not humid. If there is too much moisture in the air this can cause Carbonation that is the reaction of the resin mixture with the moist air that results in defects.

During winter, it is advised to store the resin in a warm area.

Pre-Production Testing

The application process of pouring an epoxy resin is not difficult. But we suggest to make various tests to develop your standardized application process especially if there is no previous experience with resins. Cromas Paints goal is to give you the most useful information so your projects are successful. The provided information comes from our direct experience.  Because there are many factors to consider, we always advise to proceed with product testing in a controlled working environment and using the same materials.
