BASF Elastospray® LWP 1672/4 - Closed Cell Spray Insulation

This system is particularly formulated to obtain a BS 476-7 Class 1 foam with an applied density between 39 and 43 kg/ m³. 

Features and benefits:

• Elimination of thermal bridges. The insulation material is continuous, without joints or cracks, even in hard-to-reach places.
• Excellent adhesion to the substrate. The spray foam bonds to most surfaces without the need for glues or mechanical fasteners.
• Speed of application and mobility. The in-situ production allows for quick transport, without the need for moving and storing high-volume materials, typical for other types of insulation materials.
• The spray process is especially suitable for insulating large surfaces, including irregularly shaped surfaces such as undulated roofs.
• The product is free of ingredients with high global warming potential by greenhouse effect (GWP) affected by the regulation (EU) No 517/2014.
• Shelf life of components: component A: 120 days, component B: 180 days.

The mixture reacts on the surface, adhering to it instantaneously, and expands into rigid foam.

Machine conditions:

• Mixing ratio of components: 1:1 (volume).
