Flammability ASTM E


HDC Fossil CHPL outdoor interpretation panels have a 162 flame propagation index of 10 (Radiant Panel) to 15 without drip of flame for a 1/10" to 1/2" thickness outdoor signs & exterior panels.

NEMA LD3


HDC Fossil CHPL outdoor interpretation panels exceed the standards for decorative laminates established by the National Electrical Manufacturers Association NEMA LD3-1991. These standards establish the minimum criteria for resistance to wear, boiling water, high temperature, cigarette burns, fading, dimensional stability, staining, appearance and formability (bending and post forming grades).

Chemical & Stain Resistant


HDC Fossil CHPL exterior interpretive panel are perfectly suited for commercial use where chemical products are used. HDC Fossil cHPL outdoor interpretation panels are resistant to common household products, solvents, mild alkalis, and diluted mild acids. Some staining agents, especially those with grease bases paint or ink, will require the use of a solvent for removal. These stains can be removed using turpentine, 100% mineral spirits, isopropyl “rubbing alcohol”, Goof Off “Graffiti Remover” or WD-40, lacquer thinner, acetone or MEK.

Static Electricity


HDC Fossil CHPL outdoor interpretation panels do not store static electricity and are therefore suitable for use in controlled environments where accumulation and retention of static electricity must be avoided.

Fire Retardant


HDC Fossil CHPL outdoor interpretation panels are suitable for application where fire retardant properties are required by building codes.

Toxicity Test


HDC Fossil CHPL exterior grade interpretation panels have passed the LC50 Pittsburgh Protocol Toxicity Test and are equal to and no more toxic than wood or paper.
