3M has joined forces with Norwood Partition Solutions of Hyde, Cheshire, UK to develop a bonding solution for glazed partition systems used in cleanrooms.
The solution uses 3M’s VHB tapes to bond panes of glass into partition sections in aluminium or other materials to provide a ‘flush’ glazed unit.
The previous method required an external bead or tape protruding from the joint, often with visible air bubbles, meaning the glass had to be screenprinted to conceal it, which could take up to four weeks and add to the cost. The VHB 4947F tape naturally prevents air entrapment and can be easily applied using a semi-automatic laminator, the company says. This leaves no tape protruding so there is no need for a bead or extra screenprinting. In pharmaceutical production where hygiene is paramount, the flush fitting of the tape also means there is less opportunity for dirt to accumulate, which has a positive impact on cleaning costs, the company adds.
‘While the level of bonding in our previous system was not a major issue, the unsightly protruding tape, and the additional cost and delay created by having to commission printed glass, was not offering the best possible solution to customers,’ said Andrew Boydell of Norwood. ‘By working with 3M, we have been able to deliver a solution which doesn’t just look good but also offers clear performance advantages in hygiene-critical applications.’
