Definitions

• the present disclosure relates to a laminated non-woven containing a high-performance adhesive and a silicone-based liner.
• Vinyl self-adhesives use water-based acrylic adhesives that pose a disadvantage in their characteristics of adhesive ability, tack (initial strength of the self-adhesive, required for immediate adherence onto the object), and shear (which determines the durability and attachment of the adhesive onto the substrate) when compared to Hot melt adhesives (100% solid and holding defined adhesive ability characteristics), especially when applied to substrates under low temperatures.
• the self-adhesive non-woven is made of a porous structure and its production uses non-vinyl polymeric raw materials and hot melt adhesive glue, which is sensitive to pressure and adheres permanently, besides having surface evenness and excellent resistance to traction, thus solving the aforementioned technical problems.
• the self-adhesive non-woven developed can be employed, and is recommended, for various applications given its adhesive provides adherence to a wide variety of substrates as a function of its good surface evenness and excellent resistance to traction.
• the self-adhesive non-woven is a product recommended for non-conventional applications. Detailed description of the disclosure
• a first layer made of a single- or multi-layered non-woven , 100% fibrous or micro fibrous polypropylene; a second layer made of Hot melt (PSA - pressure sensitive adhesive) glue; and a third layer made of a silicone-based liner, called a paper liner.
• PSA Hot melt
• the production process for the disclosure mentioned above comprises three stages: making the liner silicone-based, making the liner adhesive, and lamination of the non-woven to the adhesive liner.
• the suitable non-woven for the application of the adhesive contained in the first layer of the present disclosure, has a medium/heavy weight ranging from 30 to 150 g/m 2 , preferably 45g/m 2 , with an average pore of 33 micros and a maximum pore of 70 micros, containing an air permeability from 50 to 150 m 3 /min/m 2 , this value preferably being 88 m 3 /min/m 2 .
• Figure 1 shows a cross-section of the end-product, detailing the three layers formed
• Figure 2 presents a front view of the self-adhesive with a detail of the non-woven shown when the paper liner is removed;
• Figure 3 shows the three layers making up the self-adhesive non- woven in this embodiment, namely: paper liner, psa glue, and the non-woven .
• the non-woven can be manufactured with more than one layer, thereby resulting in a multi-layered product.
