Jotun Vinyguard Silvergrey a Fast Air Drying vinyl primer sealer tiecoat. Improves Adhesion onto existing painted surfaces.
It is recommended as a tiecoat underwater to bond the antifouling system or to seal previously applied unknown coatings. It may also be used as a primer underwater on wooden vessels or as part of an air drying system for topsides.
Application methods include spray: either air spray or airless spray. Brush which is recommended for stripe coating and small areas. Care must be taken to achieve the specified dry film thickness. Roller which may be used for small areas. Not recommended for first primer coat. Care must be taken to achieve the specified dry film thickness.
Drying and curing times are determined under controlled temperatures and relative humidity below 85%.
The coating of Vinyguard Silvergrey 88 will be resistant to various immersion temperatures depending on the specific chemical and whether immersion is constant or intermittent.
Vinyguard Silvergrey 88 is available in 5 and 20 litre tins and has a minimum shelf life of 48 months within a cool, dry and well ventilated space that is away from any sources of heat and ignition.
Vinyguard Silvergrey 88 is a fast air drying vinyl matt coating which can be used as a primer or intermediate coat in atmospheric and immersed environments, also as a tie coat for antifouling systems. It can be applied direct to steel and wooden hulls by Airless spray, Conventional spray or roller.
Vinyguard Silvergrey 88 is recommended for topside, deck and superstructure on steel and wood vessels. It can be used as a tie coat over sound unknown existing coatings to upgrade the system to a Jotun marine specification. Vinyguard Silver-grey can be applied up to 100 microns in a single coat by airless spray, two coats may be required to achieve the recommended DFT by roller. It is resistant to continuous temperatures of up to 60°C and 40°C in immersed sea water.
To secure lasting adhesion to the subsequent product all surfaces should be clean, dry and free from any contamination.
For carbon steel it is recommended that the surface is blast cleaned which makes it free of all visible oil, grease, dirt, dust, rust or any existing coatings.
For coated surfaces it is recommended that the surface is clean, dry and doesn’t have any damaged coatings.
Depending on the substrate temperature you are applying Vinyguard Silvergrey 88 at will depend on how fast the drying and curing time will be. The fastest the product will dry is at 40°C, this will result in the product being touch dry in 10 minutes, walk-on-dry in 1.5 hours and dry to over coat in 2 hours. For the full drying and curing times check the Vinyguard Silvergrey 88 data sheet.
Vinyguard Silvergrey 88 is also able to resist heat of up to 60°C continuous heat in dry atmospheric environments and can resist heat of up to 40 °C continuous heat in immersed sea water environments as well as a peak heat of 50 °C.
Peak temperature duration is a max of 1 hour and the temperatures listed relate to retention of protective properties. However, aesthetic properties may suffer at these temperatures.
Depending on the actual exposure of the coating system, various primers and topcoats can be used in combination with this product. Some examples for a previous coat include epoxy and epoxy mastic. Also, some examples for a subsequent coat include alkyd, acrylic and antifouling system.
Containers of Vinyguard Silvergrey 88 must be kept in a dry, cool well ventilated space and away from sources of heat and ignition. The minimum shelf life for this product is 48 months at a temperature of 23 °C.
