Cutting and weeding
Because of the difference in thickness and density of various films, the cutting depth and pressure of the blade needs to be adjusted for each type of material. The cut should be deep enough to allow easy weeding but not cut the surface of the liner paper. If the blade is set such that it cuts into the silicone layer of the liner, the liner may delaminate to the vinyl when weeding. HEXIS vinyl films carry a solvent based adhesive and thus are suitable for wet application.

Surface preparation
For best results the vinyl should be applied to a clean smooth surface free of any traces of oil, grease, wax, silicon and other contaminants. Prior to the application of the vinyl the target surface should be cleaned with HEXIS degreaser and wiped dry with a dust free cloth. Sufficient time should be allowed for the degreaser to evaporate completely after cleaning. Other solvents may alter the target surface or reduce the adhesion properties of the vinyl film. Application should not take place at temperatures below +10°C (+50°F). Surface contamination and application below minimum temperatures are avoidable causes for adhesion failure.

Adhesion is best when the target surface is flat and smooth. Thus we do not recommend application onto untreated, dusty or friable substrates where the surface contact is reduced such as on wood, fabric, foam, unglazed ceramics, brickwork, plaster, raw concrete and embossed or grainy surfaces. Care should also be exercised with plasticized materials and substrates prone to outgassing such as fiberglass, polycarbonate and certain paints and varnishes.

Transfer
All brands of application tape can be used with SUPTAC. We recommend a medium tack high grade transfer tape. For small letters and matte vinyl we recommend use of a high tack application tape; for larger designs and gloss vinyl are medium tack tape is preferable. For very large, complex and multi-layer designs that may require repositioning consider using a clear transfer film and wet application. The transfer tape should be applied with care to cover the complete cut vinyl area. Turn over and wipe the paper liner firmly with the help of a HEXIS squeegee with the film facing downwards and the paper liner facing upwards.

To remove the silicone paper from the vinyl the film should be laid upside down, i.e. with the application tape on the work surface and the silicone paper face up. Position the vinyl on the target surface and peel the silicone paper gradually as you progress over the work surface. The silicone paper should always be peeled back from the vinyl, never the other way round. Using the squeegee and firm pressure wipe the vinyl down in wide sweeps and remove the application tape by peeling it back at a 180° angle. Never use a plastic squeegee directly on the vinyl surface. To ensure correct adhesion on curved and other difficult areas once the application tape is removed, carefully wipe again with a HEXIS felt squeegee.

Extreme care should be taken when applying warm air from a heat gun. Temperatures must not exceed +50°C (120°F) and a practice trial should be carried out before final application.

Storage
Vinyl film should be stored on the roll in a plastic sleeve in their original carton standing upright at 15 to 25°C (59 to 75°F) and 50% relative humidity. If rolls are stored at higher temperatures adhesive alterations and/or shrinkage may occur. If the material is stored lying horizontally, flat spots may develop in the contact area as the soft vinyl will assume the texture of the surface it is resting on. If the rolls are stored in humid conditions or on a damp floor, the liner paper may absorb moisture causing distortion. 

In order to maximize performance and adhesion properties use the material within 12 months from date of purchase.

For additional product information consult the data sheets.

For advice on specific substrates check out the Guide to Substrates.

In general please note, the performance of the adhesive is affected by a number of factors such as temperature, humidity, surface condition  and application method. Our suggestions and recommendations for the use of HEXIS products are based on tests and experience and do not constitute a warranty. The user must ensure the suitability of any product for his intended purpose under his own working conditions prior to purchase. If in doubt about the compatibility of the adhesive, the vinyl film or the degreaser with any particular target surface we recommend that you carry out a trial on an inconspicuous area before application or seek advise from the manufacturer. In all cases refer to the data sheet.
