600ml SIGA Primur Tubular Bag - Permanently Elastic Adhesive Sealant

600ml SIGA Primur Tubular Bag is a permanently elastic, high‑performance adhesive sealant supplied in a tubular foil pack for creating airtight, wind‑tight and movement‑tolerant connections between vapour control layers and solid building components. It offers precise application, strong adhesion, and long‑term durability for professional airtightness detailing. SIGA Primur Tubular Bag is a cartridge‑applied elastic sealant designed for forming airtight connections between membranes (VCLs, airtight layers, underlayments) and adjacent building elements such as concrete, masonry, timber and metal. The permanently elastic formulation allows the joint to absorb structural movement without cracking or losing airtightness.

Unlike conventional sealants, Primur is engineered specifically for airtight construction, providing high initial tack, excellent ageing resistance, and reliable long‑term performance. The tubular bag format is ideal for professional applicators, offering consistent bead size, reduced packaging waste, and compatibility with standard foil‑pack guns. Its high‑performance adhesive compound bonds securely even at low temperatures, ensuring dependable results across a wide range of site conditions.
