DuPont™ Corian® Private Collection Series

Fabrication Considerations

2010

2

Private Collection Series Characteristics

The Private Collection Series has characteristics that requires some specific fabrication methods

• Directional veining that ranges from subtle to bold

• The edge of the sheet has a different appearance than the top

• The shade may change slightly through the thickness

• Some colors have abrasive content that shortens tool life

• Sheet yield may be lower – need to consider when quoting jobs

It is important to understand these characteristics and be able to set customer expectations

• Physical samples help in setting expectations

Veining

Directional

• Need to consider sheet orientation when seaming

Random

• Unless you have two consecutive sheets there will be a break in the pattern when seaming

Edge appears different

• Have side view of vein

Veins vary through thickness

• Cutting into sheet (rebating, coving) will reveal a different vein pattern

Vein influence on background color stronger on the surface

• Interior of sheet may have slightly different shade

4

Directionality

Definitions

• MD – Machine Direction (along length)

• TD – Traverse Direction (along width)

The veins generally run along the length (MD)

Most uniform appearance is when all sections run the same direction

Avoid MD-TD (90°) Butt Seams

SeamingRecommended

• (1) End to End (MD-MD)

• Side to Side with same orientation

• (2) MD-MD

• TD-TD (not shown)

• (3) Miter Seam

Not Recommended

• (4) MD-TD Butt Seam

Edge Buildups

(1) V-groove Edge

• “top” of sheet visible on both surfaces

• Pattern can “flow” over edge

• Good with minimal radius

(2) Stacked Edge

• Edge of sheet visible, see edge of veins

• Not identical to top of sheet, but “flows”

• Works well with many profiles

• May see “layers”

(3) Drop Edge

• Side view has edge of top sheet, “top” of dropped edge

• Visible pattern difference for most Private Collection colors

Coved Backsplashes

Coves have two transitions in a short distance (deck-cove-backsplash)

• There is a visual break in pattern

• Some colors may appear a different shade in the cove

• Veins may be more prominent in cove

• Some colors with more subtle patterns may work

• Best practice is to show customers physical samples to set expectations.

12

Alternate Corner Designs

• Variations of Mitre corners• Stepped

• Swooped

• Fan

• Alternatives to straight mitre• Must have proper seam support strip

• Seam support strip must be supported properly

• Seam support must be filled completely with adhesive

• Higher cost to consumer helps to blend the pattern for better appearance

Other Considerations

Some colors have ingredients that increase tool wear• Ecru, Cirrus White, & Natural Gray (Camel – Library Color)

Private Collection colors can appear to be “softer” when finishing

• Use care to get the proper finish

Thermoforming• Heat to the lower end of the recommended range (150-160°C / 300-320°F)

17

Summary

Private Collection colors have large scale patterns that require some extra considerations

• Design and price with directionality in mind

• Don’t base pricing on area and sheet price, yield may be lower to keep segments in the right orientation

• Not all fabrication methods are suitable, those that work with subtle patterns may not work with bolder patterns

• Some colors have abrasive content that shortens tool life

Avoid surprises

• It is important to understand these characteristics and be able to set customer expectations

• Physical samples help in setting expectations
