The Vueguard® 931AF
is one of Performance Coatings International’ Laboratories, LLC’s families of solvent-based UV cured coatings for plastics. Vueguard® 931AF
is a crystal clear coating offering permanent, superior resistance to fogging. There are a variety of formulations each responding to particular application needs ranging from very high condensation to low condensation environments and abrasion resistance.
Range of Uses
The Vueguard® 931AF
is used where potential fogging conditions exist, i.e. humidity, moisture in both indoor and outdoor environments. Examples of excellent fog resistant performance applications include the following:
|Eyewear – prescription, sport and safety
|Refrigerated vending machines
||Glazing windows, skylights, etc.
Coating Application Methods
may be applied via spray (hand or automated), dip, spin, roll or flow coating.
has been tested in both hot and cold extremes for extended periods of time without fogging. Depending on the application formulation, this coating will not fog over a water filled beaker at 90°C for over 85 minutes when the test was stopped. When breathed on, the coating remains unaffected (clear) at all times.
Clarity and Versatility
An important property of the Vueguard® 931AF
is its optical clarity. The Vueguard® 931AF
has many applications. It can either be used alone as a one-sided coating or in conjunction with another coating, such as the hard coat Vueguard® 901
to provide crystal clear solutions with high abrasion resistance on the outside surface and permanent anti-fog properties on the interior surface, as for example, in ophthalmic lenses and instrumentation gauges. This coating has no effect on light transmission characteristics.
Scratch and Abrasion Resistance
is not intended to be used where a high-degree scratch and abrasion resistance is required. Minimal scratch and abrasion resistance is provided with Vueguard® 931AF
coatings to allow for handling and cleaning. Scratch resistance ranges from a high of 5 psi with a #0000 steel wool pad PCI Labs test to less than 1 psi depending upon the formulation.
coated products may be cleaned using ordinary liquid window cleaners and a soft cloth.
