Application temperature
* To ensure proper adhesion between the tape and the cleaned substrate, bonding materials must be applied when both the substrate and tape temperature is between 15° C and 38° C. The temperature needs to be consistent for at least one hour after
application.
* It is recommended that vehicle conspicuity markings are stored at temperatures between 18° C and 28° C.
Where to apply
* Use the guidelines provided in Regulations (such as: ECE 104, DOT FMVSS 108) to ensure that the markings (tapes) are in
general positioned correctly on the vehicle.
* The user is responsible for determining whether the V-MARK™ product is fit for a particular purpose and suitable for the user’s
application.
* Users are urged to carefully evaluate substrates for material adhesion and compatibility.
Listed below are guidelines for selected substrates. Material failures caused by the substrate or improper surface preparations
are not the responsibility of manufacturer or its distributors.
Two-part polyurethane paints
* Two-part polyurethane paints must be cured before applying V-MARK™ markings (tape). If the paint is not properly cured,
outgassing will cause bubbles to form under the applied material and the adhesive will not adhere adequately.
* V-MARK™ recommends testing for outgassing prior to applying vehicle conspicuity markings (tape).
* For drying times, paint manufacturers’ guidelines are to be followed in all instances. While most paints are usually touch-dry
within a few hours, dependent upon the primer, paint mixture and thickness, proper curing may make significantly longer, up to
one week.
GRP (Glass Reinforced Plastics) and/or gelcoated surfaces
* Similar guidelines to the above will apply for composite materials such as GRP substrates and/or gelcoated surfaces, in that
the substrate must be properly and fully cured before applying, otherwise outgassing may result.
Outgassing Plastics
* Polycarbonates, Polyprenes and other plastics can interact with the environment absorbing or outgassing moisture, or outgassing processing aids and solvent carriers for additives, which might cause the formation of bubbles on the film. Preliminary tests are essential to ensure that no adverse effects arise from this interaction.
Stainless Steel
* The same application guidelines and warranty as the standard product apply.
Surface cleaning
* The purpose of cleaning the substrate is to remove any dirt or contamination.
* It is very important that the surface is free of dust and grease, and ideally the surface should be smooth.
* Use a clean cloth with isopropyl alcohol to wipe the surface in one direction only to avoid spreading contamination. With a dry
clean cloth wipe away the cleaner before evaporation.
* Repeat this process until the surface is clean, i.e. when there is no visual dirt or contamination transfer onto the cloth.
Ensure the surface is dry and the isopropyl alcohol has completely evaporated before commencing application.
