one gallon bottle, HF stands for Hazard Free. During its development over 100 formulations were tried before the current formula was achieved. HF-100 is not only safe but is also able to be shipped without any restrictions. HF-100 is nonflammable, non-toxic, non-ozone depleting, low VOC blend of surfactants, emollients, isoparaffins, and water. It is completely ODC free and proper use can reduce VOC emission by up to 70% and has a slower evaporation rate that minimizes ventilation requirements. When used as directed, HF-100 is a very economical solution, and requires 60% less volume than standard solvents to adequately activate the tape. It is also odorless and colorless and works with any double sided grip tape. Track Page Views WithAuctiva’s Counter
