Xrunner question on how you used the "MEK", I can purchase it 100% pure does just MEK by itself weld?
According to the MSDS for PLASTRUCT PLASTIC WELD CEMENT
Methylene Chloride*# (Dichloromethane) 80-90%
Methyl Ethyl Ketone (MEK) 5-15%
I've used CHCl
3 (Chloroform) and CH
2Cl
2(Methylene Chloride) to plastic weld LOADS of plastics before. I have never tried using MEK though I have some in the lab. I'm not sure if the MEK works on different plastics than Chloroform but the Chloroform/Methylene Chloride works wonders. I have repaired broken parts on instruments before that were basically as strong as new. One piece in particular, was a stop on an instrument door. Someone slammed open the door on an instrument and broke the stop. Plastic weld it back in place, it hasn't broken off again in three years of daily use.
Just found a convenient list:
Plastics that both will do:
- Polymethyl methacrylate (Acrylic)
- Cellulose acetate butyrate (Butyrate)
- Low density polyethylene (LDPE)
- Polycarbonate
- Copolyester (Polyethylene terephthalate glycol - PETG)
- Polystyrene
- Polyvinyl chloride (PVC)
Plastics that only CHCl3/CH2Cl2 will do:
- Cross-linked low density polyethylene (PEX)
- Ultra high molecular weight polyethylene (UHMW)
- Polyester (Polyethylene terephthalate - PET)
- Polypropylene
Plastics that only MEK will do:
- Acrylonitrile butadiene styrene (ABS)
- Polyacetal (Delrin - POM)
- High density polyethylene (HDPE)
Plastics that NOTHING will weld:
Looks like I need to take home some MEK.
