PC-Sealcoat® PUR HV

Two-component, 100% solid, flexible hybrid polyurea system

PACKAGING

PC-Sealcoat® PUR HV available in 200 kg barrel (Amine side)
225 kg barrel (Iso side)

PC-Sealcoat® PUR HV is a fast-curing, aromatic, and flexible two-component polyurea coating system renowned for its rapid setting properties. Formulated through the reaction of an isocyanate prepolymer with an amine-terminated resin blend, this system guarantees impeccable purity. Designed as a protective barrier for various surfaces including concrete, metal, wood, ceramic, geotextile, and PU foam substrates, it delivers seamless waterproofing coupled with outstanding durability. Noteworthy for its elevated resistance to moisture and temperature variations, this coating can be applied under challenging environmental conditions. Application necessitates the use of high-pressure, heated plural-component spray equipment. PC-Sealcoat® PUR HV complies with the stringent requirements outlined in EN 1504-2 for concrete surface protection systems.

SURFACE PREPARATION

Surface preparation plays a pivotal role in determining the efficacy of coatings. When working with concrete substrates, it is imperative to mechanically prepare them via abrasive blast cleaning to eradicate cement latitude and establish a textured surface. Any compromised concrete should be removed, and imperfections such as voids must be exposed.
Essential repairs, void filling, and surface leveling should be executed using appropriate products. Prior to coating application, ensure thorough removal of all dust and loose materials from surfaces, ideally employing a brush and/or vacuum. The surface’s pull-off strength for coating application should be a minimum of 1.5 N/mm², with concrete residual moisture not exceeding 4% pbw (in the case of a moisturetolerant primer, a maximum moisture level of 6% pbw is permissible). Moisture levels should be gauged using a moisture meter. To avert condensation, ascertain that the substrate temperature remains at least 3 °C above the dew point. The relative air humidity during application should not exceed 85%. Before applying any coatings, confirm the substrate’s moisture content, relative air humidity, and dew point.

PRIMING And APPLICATION

For optimal surface smoothness and robust adhesion, priming the application surface is imperative. A light application of 0.3-0.8 mm quartz sand is recommended to improve adhesion and extend the drying period of the primer before the polyurea coating is applied. To prevent the formation of blisters, it is essential to refrain from excessive sand broadcasting.

The PC-Sealcoat® PUR HV application process necessitates prompt action, ideally within 12-24 hours following the application of the primer, utilizing a two-component high-pressure and heat spray apparatus. The Isocyanate prepolymer and amine resin should be administered in a 1:1 volume ratio, both maintained at temperatures exceeding 70 °C. It is imperative to uphold consistent temperature and pressure levels throughout the application while ensuring regular monitoring to optimize performance. Avoid any form of dilution to the PC-Sealcoat® PUR HV system components. Prior to application, diligently blend the amine component using a barrel mixer for a minimum of 30 minutes until a homogenous mixture with a uniform
color is achieved. Though aromatic PC-Sealcoat® PUR HV coating systems provide UV stability, exposure to sunlight may induce color alterations without affecting functionality. To preserve color consistency, promptly apply an aliphatic top coat within 12 hours following the base coat application.

SHELF LIFE & STORAGE CONDITIONS

PC-Sealcoat® PUR HV components exhibit sensitivity to moisture. It is imperative to store them in securely sealed containers to preserve their quality. Before application, it is essential to adequately blend the amine resin. Storage of PCSealcoat® PUR HV components should be within the temperature spectrum of 20 to 30°C. The unopened original packaging has a shelf life of nine months from the date of manufacture.

Contains isocyanate MDI. Avoid breathing vapors. Avoid contact with skin and eyes. Take precautions during application. Wear suitable protective clothing, gloves and eye/ face protection. Adequate ventilation of the working area is recommended.
