Claims
- 1. A process for making a multilayer louver slat wherein one or more outer opacified pearlescent layers are combined with a base layer, which is a substrate for said outer layer(s), said outer layer(s) comprising a polymer matrix, pearlescent pigmentation, and opacifying pigment such that a 4 mil thickness of said layer(s) not in combination with said base layer, has a percent reflectance ratio according to TAPPI method T 425 om-86 of between about 60% and about 90%, so as to provide a pearlescent appearance and light blocking features in one louver.
- 2. The process of claim 1 wherein the pearlescent layer is coated on to a base layer.
- 3. The process of claim 2 wherein the opacified pearlescent layer is painted by spraying or dipping an opacified pearlescent coating onto one or both faces of a base layer.
- 4. The process of claim 1 wherein one opacified pearlescent outer layer contains an extrudable thermoplastic polymer and is extruded onto a base layer.
- 5. The process of claim 1 wherein at least one outer layer is an opacified pearlescent layer and is an extrudable thermoplastic compound extruded onto a base layer.
- 6. The process of claim 1 wherein at least one of the outer layers is an opacified pearlescent layer and the outer layer(s) are co-extruded with an extrudable base layer.
