Exterior Polyurethane Architectural Moulding
Exterior polyurethane architectural mouldings engineered from high-density rigid polyurethane (150-220 kg/m³) transform building facades with timeless decorative details. Designed with wood-like mechanical toughness and high impact resistance, these exterior mouldings will not split, warp, or decay under severe frost or hail impact (dimensional stability tested between -20 °C and +70 °C). Their closed-cell structural formulation offers low water absorption (below 1%), ensuring moisture resistance against rain and dampness. Pre-primed with a factory white acrylic technical primer, Polure exterior mouldings require an elastic, UV-resistant exterior facade paint. Installation calls for clean substrate preparation, 45° miter jointing, continuous PU assembly adhesive, and mechanical screw fixing (silicone adhesive is strictly forbidden). Lightly sand with 180-220 grit paper prior to painting for ideal coating durability.

Frequently Asked Questions
Why is high-density polyurethane superior for exterior mouldings?
It provides high density (150-220 kg/m³), high resistance to rot, low water absorption (below 1%), and thermal stability.
What paint should be applied to exterior polyurethane mouldings?
Topcoat with an elastic, UV-resistant exterior facade paint system for maximum weather protection.
How is exterior polyurethane moulding installed?
Mount using a continuous bead of PU assembly adhesive along with mechanical screws. Silicone is strictly forbidden.
