The Tackified fabrics have a light coating of glue on one or both sides, to enable the laminator to position the fabrics into the mould in a dry state to ensure their placement.If not in exactly the correct position, they can be pulled off and re-stuck in place. SGTF have worked with a major glue manufacturer to ensure that it is compatible with the resins that our customers are using this has been our biggest challenge in the development of the product.
Unlike similar offerings, SGTF low-tack adhesive fabrics do not require any release paper, eliminating the time-consuming process of removal and disposal.
Any large moulding with sloping or vertical surfaces will benefit, so this includes not just boat hulls but many forms of transportation and large industrial mouldings. The benefits are not in the end-component, instead they are in the ease of processing. The moulder can lay down all his reinforcements, including a core, and they will remain in position until the vacuum bag is in place and the component is infused.
All SGTF reinforcements are available in Tackified form on one or both surfaces. This includes multiaxials, woven roving and specialty 3-D fabrics.
This procedure has been developed in response to what SGTF sees as a major move by the industry to closed moulding applications - RTM, RTM-lite and infusion technology. The expanded product range includes well-known products such as Multimat, Multimat-Lite, Multicore, Multifilo and recently Maxflow. Now all of these and other products can be Tackified.
