Low expansion polyurethane foam for montage

USE

CHARACTERISTICS

PACKAGE

Prefabricated foam for ducts is a one-component structural polyurethane foam specially designed for maximum efficiency with low expansion, suitable for use at temperatures up to +35°C. This foam has an excellent structure even at +5°C and offers excellent adhesion to concrete, mortar, walls, wood, polystyrene, softened PVC, baked bricks, and gutters. It is ideal for filling cracks, installing window and door frames, insulating pipeline systems, fastening insulators and protective pipes in walls, and quick installation of the roof and roof channels.

Preparation and application :

Use on dust-free and degreased surfaces. Cover devices and other surfaces to prevent them from getting dirty. Before applying, we recommend that you moisten dry substrates with water using a sprayer for better foam structure. Use BK-Pur Premium foam by removing the cap and screwing the spray tube onto the top of the foam container. Shake the container vigorously (at least 30 times) before use. Fill large joints in several layers and moisten between each layer. The time it takes between two layers of foam is 15-30 minutes. Dose sparingly; the foam volume increases approximately twice after application, but retains its shape after final hardening. To clean and remove foam residue, use BK-PU Cleaner while the foam is still soft. Hardened foam can only be removed mechanically. See product data sheet for detailed instructions.

Expiration date and storage :

Store in a dry place in original packaging at +5°C to +25°C, protected from sunlight and freezing. Expiration date stamped on the packaging.
