Industrial floors have to withstand extreme conditions

Industrial floors face particularly high stress day by day. They also must meet high occupational safety standards have to look well even in demanding conditions. Polyurethane systems have proven to be extremely reliable in this application. They show:

• Very good abrasion resistance
• Impact and pressure resistance
• Outstanding chemical resistance
• Good Light and weather resistance
• Jointless application, good crack bridging
• Good durability

Often 2mm self-leveling layers may be coated with suitable sealers or with pure thin film coatings, e.g. anti-dust coating systems. Get more on primers and sealers. For more information on electrically conductive systems our experts can provide recommendations.

Case Study: Long-term protection of construction

A typical industrial floor coating:

Some starting formulations:

RR 5301/1	Two-component polyurethane floor coating tough but flexible, self-levelling (Desmodur® VL / Desmophen® 1150)
RR 5391	One-component polyurethane floor coating solvent-borne, gloss (Desmodur® E 21)
RR 5392	One-component polyurethane floor coating solvent borne, pigmented with pigment pastes (Desmophen® 1100 BD / Desmodur® E 21)
RR 5393	One component polyurethane floor coating solvent-borne, thixotropic, eggshell matt (Desmodur® E 23)

Specialty: Industrial flooring for the food industry

Desmolith® technology is particularly interesting for floor coatings in the food industry: By mixing polyurethanes with cement and/or hydrated lime the carbon dioxide which is released when exposed to water is absorbed. These resulting coatings are extremely resistant to chemicals.












The Desmolith product range:

	Type	Solids in %	% OH on solids	Viscosity mPas at 23°C	Characteristics
Desmolith® VP LS 2766	Polyalcohol- emulsion	90	approx. 17.8	1200	Very resistant against chemicals, good flow characteristics
Desmolith® XP 2656	Polyalcohol- emulsion	70	approx. 4.3	250	Very resistant against chemicals, good flow characteristics
Desmolith® XP 2761	Polyalcohol- emulsion	70	approx. 4.3	200	Very resistant against chemicals, good flow characteristics
