The Vueguard^® 931 is one of Performance Coatings International’s families of solvent-based UV cured coatings for plastics. Vueguard^® 931 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^® 931 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              Marine equipment

              Aerospace                                                    Construction vehicles

              Refrigerated vending machines                          Refrigerator windows

              Greenhouse windows                                      Glazing windows, skylights, etc.

Coating Application Methods

Vueguard^® 931 may be applied via spray (hand or automated), dip, spin, roll or flow coating.

Fog Tests

Vueguard^® 931 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^® 931 is its optical clarity. The Vueguard^® 931 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

Vueguard^® 931 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^® 931 coatings to allow for handling and cleaning. Scratch resistance ranges from a high of 5 psi with a #0000 steel wool pad PCI test to less than 1 psi depending upon the formulation.

Cleaning Instructions

Vueguard^® 931 coated products may be cleaned using ordinary liquid window cleaners and a soft cloth.
