Silic8 AF1 Adhesive

Silic8 AF1 is a water based mineral adhesive and primer specially designed for use with AeroGel fleece, boards or tiles. Silic8 AF1 adhesive can be used for priming and adhesion, typically mineral substrates, historic plaster, stone, brick etc.  Used in combination with Lime Green's penetrating solutions, AF1 adhesive bonds with substrates while remaining vapour open. It can be used in combination with our other Silic8 products. Patent pending. AF1 adhesive is available in 9kg or 20kg UN certified containers

AF1 adhesive is water-based, has no odour and is certified as non-combustible and vapour permeable. It is a natural mineral and water-glass adhesive and free from any other co-binders such as solvents, acrylic, gypsum and cement. Use to create a flexible, durable and non-combustible bond to adhere AeroGel fleece insulation to substrates prior to plastering and decorating.
