Dear Sir
I need some tech info on HIPPO, more than on your tech sheet.
I need film build per coat and maximum
Answer: ---- 10 -15 mils. If a second coat is needed allow all the solvents to flash but do NOT allow the coating to set and apply a second coat. If additional coats are need allow to dry. Sand and apply the additional coat. Do not apply more that 2 coats without allowing the bedliner to dry overnight.
Question:Which solvents it resists and which ones it doesn't
Answer: most solvents for short periods. Long term exposure to solvents can cause the material to swell and start to breakdown.
Solvent resistance:
MEK - Passes 100 Rubs
MINERAL SPIRITS - Passes 100 Rubs
XYLOL - Passes 100 Rubs
LACQUER THINNER - Passes 100 Rubs
ACETONE - Passes 100 Rubs
GASOLINE - Passes solvent spot test
OIL - Passes solvent spot test
METHYLENE CHLORIDE - Passes solvent spot test
Question temperature resistance
Answer: Max. 180 - 190 degrees. Product will soften if exposed to excessive heat for a long period of time. These temps. are for short intervals of under 1 hour. Normal maximum temperature range is up to 140-150 degrees F.
Question: UV resistance
Answer: Good.
After 168 hours of accelerated weathering in accordance with SAE J1960 HIPPO showed very little to no change in gloss.
After 239.5 hours panels still maintained a high gloss.
NB Original gloss can change depending on application conditions.
High humidity or water in the air lines can produce a loss in gloss during application.
UV RESISTANCE - PASS
Question:impact ratings
Outstanding, Gravel Ometer:(SAE J400),
SMC - Passes
Sheet Metal - Passes
Did this answer your question?
