PROTECT UV- TopCoat

UV- hardening surface layer of PROTECT UV-coating system

Item No. 2755

FIELDS OF APPLICATION

PROTECT UV-TopCoat is a water-based, 1-component top coat impregnation for manufactured concrete like pavers, slabs and blocks and gives them a high-quality finishing and durable protection.

PROTECT Top Coat generates a satin shining finishing that deepens the primary concrete colour and gives surfaces a glossy shining appearance.

When applied properly, PROTECT UV-TopCoat coats the concrete surface and generates an excellent water repellent film which reduces the occurrence of water penetration.
This optimises concrete's frost-thawing salt resistance and minimises visual damages like efflorescence. Contaminations from food and beverages are easier to remove (Easy-to-clean effect).

The impregnation is a very quick-drying product. In the manufactured concrete industry this quality allows packing the concrete products rapidly after application. Applied on concrete surfaces, this feature enables stepping on the surface quickly after treatment.

PROTECT UV-TopCoat shows a high scratch resistance, is resistant against chemical loads, weather-resistant, non-yellowing and abrasion resistant. The film-forming impregnation bases on a UV-crosslinking polyurethane dispersion providing high hardness, gloss and transparency.

PROTECT UV-TopCoat is applied on the dry site of the production, NIR-dried and UV-hardened.

WORKING PRINCIPLE

Being part of the double component system, PROTECT UV-TopCoat and the previously primed concrete surface (PROTECT UV-Primer) are combined to a durable and powerful protection system.

Appling a primer may reduce the risk of polymer degradation due to the high alkalinity. Usually, the primer application has the same effect like using a small quantity of the top coat.

DOSAGE | APPLICATION QUANTITY

Depending on the surface structure and its absorbing abilities the necessary amount might vary between 50 – 150 g/m² and has to be determined for each single application.
