Clear, two-part adhesive bonds acrylic faced rimless and rim and groove letters

two metal part's getting glued together

Innova Solutions has launched a clear two-part adhesive that combines flexibility with superior bond performance and clarity. NovaWeld SignFix 5 has been developed in conjunction with SignFab and delivers benefits in terms of reduced production times, final product performance and aesthetics.

Designed primarily for the manufacture of acrylic faced rimless and rim and groove letters, NovaWeld SignFix 5 bonds securely to both the stainless or aluminium return and acrylic face. After the 4-5 minute fixture time, the letter is securely bonded with the flexibility required to allow for the differential expansion that occurs between the acrylic and metal return when the letter is installed.

No shadow line

Historically, adhesives have not been able to combine flexibility with clarity and speed of cure. This has led to various methods and products being used for this application, which has resulted in costly failures when letters have been subjected to external conditions. Although not the most effective of joint designs, NovaWeld SignFix 5 compensates by exhibiting tremendous bond strength to both substrates, coupled with flexibility to bond dissimilar materials; while aesthetically, the clear cured product gives no shadow line when the letter is illuminated.

The product has been rigorously tested both in lab conditions and external weather cycles for a period of 12 months, where it was subjected to extremes of temperature, humidity and moisture. NovaWeld SignFix 5 is currently being used by the industry’s leading letter manufacturers and is available in both 50ml and 400ml cartridge sizes.
