DORSIMIX® formulated filler – the money-maker

DORSIMIX® is Dorfner’s branded range of ready-made formulated fillers used in resinous coatings for industrial and commercial flooring. DORSIMIX® is a versatile product used for both pre-filling and for broadcasting onto fresh self-leveling (SL) coatings.
Whether you look at the engineering or the economics, DORSIMIX® is simply brilliant. Contractors can install high-strength flooring with minimal coating thickness while reducing consumption by up to 15% compared to conventional fillers.

DORSIMIX® – the formulated filler with a touch of genius

DORSIMIX® fillers are based on high-performance quartz sand. In the base layer, they build up a tightly-packed 3-dimensional framework which is wedged together, producing durable, high-strength floor coatings. Also, because the coatings are thin, less resin is needed.

ISG quartz sand blends are always state-of-the-art

ISG quartz sand blends are the archetypal products in the Dorfner quartz sand range. Special screening lines, the legendary ISG A, B and C blends, are regarded in many industries as the embodiment of quality, and they are even used as a generic term for high-quality quartz sand products. It is hardly surprising that ISG quartz sand blends are always state-of-the-art and are the filler of choice for resinous flooring.

At the leading edge of filler technology

ISG quartz sand blends have been used for installation of many million square meters of resinous flooring. They are the right choice for coatings which are subjected to heavy stress and loads in applications where the flooring has to be tough and virtually indestructible. Examples include wholesale and retail outlets, production and assembly plants, public buildings such as parking garages and flooring in the healthcare sector and the transportation industry.

It's what’s inside that counts

A: Color comparison between various quartz sand products B: REM image of ISG quartz sand. C: ISG quartz sand blends have a bright gray color and rounded grains. This monocrystalline sand is very hard, making it the ideal filler for resilient resinous floor coatings.

The secret is in the blend

Dorfner quartz sand blends are mixed in situ, which takes a lot of effort and expertise. Our proprietary process ensures batch-to-batch reproducibility on the screening lines, which is an essential quality attribute of our ISG quartz sand blends. This translates to high dependability and consistently good results for users of our quartz sand blends.

Sturdy support matrix

DORSILIT® is a key structural component which makes resinous flooring resilient enough to withstand significant abuse. Our quartz sand particles build up a tightly-packed 3-dimensional framework in the resin matrix. DORSILIT® quartz sand is compatible with all standard resins and is suitable for pre-filling and for broadcasting onto fresh coatings.

DORSILIT® quartz powder adds stability

DORSILIT® quartz powder is made from high-quality quartz which is extracted from our own deposits. The pure light-gray quartz passes through a grinding and fine screening process. The powder is used as a special filler for resinous flooring, and it is a standard ingredient in many filler formulations.  It is so fine that the particles easily slip into the gaps, reinforcing the 3-dimensional framework of coarse particles. Due to their irregular shape, the particles are wedged in place similar to what you see at the macro level in a dry stone wall. The Dorfner “low void” grains increase the strength of the base layer on a floor by a factor of 10.

Major constituent of floor coatings

DORSILIT® quartz powder is a major ingredient in many filler formulations. Well-known manufacturers use it in many of their resinous flooring installation systems. Because of the wedging action and “low-void” functionality, quartz powder greatly increases the strength of floor coatings.
