PRODUCT DESCRIPTIONPart of a wider family of POLYRESYST™ products, these one- or two-component
polyurethane priming systems, are designed to preserve, rehabilitate and prolong thedurability and lifetime of different substrates.
Primarily developed for porous materials such as concrete and wood, ourPOLYRESYST™ primers can also be used for non-porous substrates such as steel,asphalt, ceramics and rubber.
POLYRESYST™ primers are easy to apply and adhere well to surfaces that need
to be prepared ahead of the application of a new coating, a protective system, or anadhesive.
Addressing regulations regarding the use of volatile organic compounds (VOCs), ourPOLYRESYST™ primers are suitable for use in a wide variety of coating and adhesiveapplications.

KEY BENEFITS• Excellent adhesion to a variety of substrates• 100% solids, low VOC, low emissions• A fast application time and recoat window• Easy application due to low viscosity, resulting in less product waste• Help prolong the life of concrete, metal and wood products

One-or two-component solutions for your needs
Operating at the forefront of the specialist polyurethane chemistry
for many years, we have developed an extensive range ofMDI-based primer systems.

Our POLYRESYST™ primers portfolio includes high quality grades
which have been tailor made to enhance the processing, applicationand performance of coatings and adhesives, used in a variety ofapplications and industries.

ONE-COMPONENT SYSTEMSPOLYRESYST™ PR1010 primer; POLYRESYST™ PR1020 primer;
and POLYRESYST™ PR2010 primer are a range of one-component
systems with varying overcoat window.
POLYRESYST™ PR1010 primer and POLYRESYST™ PR1020
primer have fast curing properties even at lower temperatures. Theirlow viscosity will enable excellent penetration of porous substrates
such as concrete. They also have film-forming characteristics
enabling use as a membrane coating. Typically, one layer of a primer
containing POLYRESYST™ PR1010 primer or POLYRESYST™
PR1020 primer will seal a substrate. However, for highly porous
surfaces, or to make a substrate damp proof, two or three layers
are recommended. Foaming problems can be avoided by notexceeding the advised coverage rate of max. 0.150 kg/m2 for eachapplied layer.
POLYRESYST™ PR2010 primer has good wetting properties on
a broad range of materials. This means it can be used as multipurpose primer, where a single solution is needed to prepare different
substrates. POLYRESYST™ PR2010 primer is well equipped toaccommodate the expansion and shrinkage changes that canoccur following variations in temperature, substrate moisture levels
or load. Typical applications include loading docks and industrial
flooring (concrete-steel) and concrete-asphalt overlap zones. Whereneeded, longer overcoat times on non-porous substrates (e.g.,steel) can be shortened by catalysis.

POLYRESYST™ 3010 two-component system has an extremely
low viscosity, enabling the deep primer penetration into poroussubstrates. The result is strengthening by chemical crosslinking.
POLYRESYST™ 3010 primer is ideal for use in industrial flooring

applications, for priming materials including concrete, steel andwood, and show excellent adhesion to a variety of substrates evenunder severe conditions e.g., when surfaces are damp.

Mandrell bending testmm> 32> 32≤3≤3Handling procedureSpecial care is required when handling our POLYRESYST™ MDIbased primer technologies, which contain reactive isocyanate
ingredients. We recommend that:or mechanical bonding. Specific preparation techniques may berequired depending on the exact substrate i.e. concrete / metal.
Primers can be applied straight from the container by brush or roller.

• Additives used in conjunction with POLYRESYST™ primers
should be low in water content

Our deep understanding of the chemistry of coatings, and our policyof continuous innovation, means we can give our customers a highlevel of proactive support. Fast and responsive, we pride ourselveson helping to solve complex coating challenges. Working closelywith our customers, we give them direct access to our laboratories
and our technical, commercial and customer support teams, which
are located throughout Europe, the Middle East, Asia-Pacific and
the Americas. This collaborative approach enables us to help
customers choose the correct product. We can also dispense bestpractice advice processing and handling MDI-based products.
Depending on requirements, we can recommend the use of oneof our many off-the-shelf solutions, which are already proven toperform. Alternatively, we can tailor our polyurethane technologies
to requirements – particularly where there is a need to create a breakinto a new application area.

• Packaging materials are stored in a climate-controlled area toprevent condensation
As with all other coatings, POLYRESYST™ primers should be applied
to surfaces that are clean and free from dirt, grease and dust. Goodsurface preparation can improve adhesion and, either cleaning thesurface to remove contamination, or priming or roughening it toactivate the surface, should provide a better surface for chemical
