产品说明:
Hylar 5000 HG is a crystalline high molecular weight powder form of polyvinylidene fluoride (PVDF)specifically designed fsolvent-based coatings to provide improved gloss. It forms mechanically strong tough films that have a broad useful temperature range. These films are highly resistant to most environmental conditions including gamma radiation are essentially transparent to ultraviolet radiation. The weatheringacteristics of Hylar 5000 HG coatings lead to excellent performance fthe long term.
Hylar 5000 is available only via a licensing program that specifies the composition of Hylar 5000 HG coatings. A properly formulated finish contains sufficient pigment to make the film totally opaque to ultraviolet radiation at the nominal one mil (0.001 inch) film thickness suggested.
SAFETY
Hylar 5000 HG is stable at temperatures up to 600°F (316°C). When it is subjected to temperatures above 600°F (316°C) fextended periods of time, hydrogen fluoride (HF) begins to evolve, at temperatures above 700°F (371°C) HF evolution becomes rapid. Hylar 5000 HG exhibits excellent flame resistance; however, in case of fire, HF traces of potentially toxic fluorocarbons can be formed. HF is corrosive, causes burns on contact, has an American Conference Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV-TWA) of 3 ppm (2.5 mg/m?) (1984).
Thermal decomposition of Hylar 5000 HG to HF can also occur in a bake oven in the event that temperatures are not controlled properly. In the event of fire, use NIOSH approved self-contained breathing apparatus skin protection to protect against volatile decomposition products. Hylar 5000 HG can be disposed
