The glue cures in 1 to 12 hours. Instant glues come in liquid form for plastic, metal and rubber, and gel form for porous materials such as wood and leather. ... White glue: Products such as Elmer's Glue-All are polyvinyl-chloride based. They are cheap and easy to use and clean up with soap and water.

There is no really a better one, they just work differently when making slime. White Glue is Water-Based, while Clear Glue is Solvent-Based. Just make sure you are using a type of glue that contains PVA!

That's: Homemade Mod Podge is PVA glue with water in it. But people are paying heaps for this crafting Must Have, to do things like decoupage and scrapbooking, that people have done for years with watered down PVA. PVA is also known as Elmer's glue or woodowrking glue or simply white crafting glue.

Simply put, PVC pipe glue does not work on all plastics. Much like wood glue is used mainly as a wood adhesive, PVC pipe glue -- more accurately known as solvent cement -- is meant to be used on the plastics in PVC pipes.

Synthetic "glues" or adhesives are generally made from a combination of polyvinyl acetate (PVA), water, ethanol, acetone and other substances. Water is used to modify the glue's consistency; other ingredients control the rate at which the glue dries out.

The chemical compounds in synthetic glue are isolated through chemical reactions. The base ingredient behind synthetic glue, vinyl acetate, is made through a chemical reaction of acetylene and acetic acid. In the presence of a catalyst, the molecular weight will increase, creating a polymer.

PVA (wood or white glue) won't work, but plastic cement will give you an almost unbreakable bond. When properly used, the plastic is often more likely to break elsewhere than along the glue seam.

What's the difference between PVA and SBR? SBR, or Styrene Butadiene Rubber, is a water resistant bonding and sealing agent, and shares many similar characteristics with PVA. One key difference is that, whereas PVA remains water soluble after drying, once dry SBR is not.
