Double sided foam tape is a permanent bonding solution as a cold glue alternative for a polyethylene tarp adhering to another polyethylene tarp. There is no solvent that has been specifically made as a cold glue for polyethylene but are solutions as alternatives.
Specialized adhesives designed for polyethylene, such as polyethylene adhesive or polyethylene repair tape, can be used to patch polyethylene materials. These products are formulated to bond effectively with polyethylene, providing a secure and durable patch. Additionally, heat welding or using a polyethylene welding kit can also be an effective method for patching polyethylene.
Hot welding with a polyethylene stick is the only way. No glue has yet been made that will effectively adhere to polyethylene.
Adhesives are used to bond (or stick) one surface to another, either temporarily or permanently.
Another name for the electrovalent bond is an ionic bond.
Another name for a dative covalent bond is 'coordinate covalent bond'.
Polyethylene glue is an 'urban myth'. Modern polyethlene materials are purposely so chemical resistant that no glue has yet been made that will bond them ! Polyethylene pipes are bonded by 'hot air' welding, not by any glues. They can be held together by contact adhesives, but the joint is very weak and will not hold even 30psi of water or air pressure.
A termination or maturity bond.
The monomer of polyethylene is ethylene - H2C=CH2. {eth=2 carbons, ene=a CC double bond} Two methane - H2CH2 or H3CH - molecules condense to form ethane: H3C-CH3 + 2 H+. Another 2 H+ removal, or condensation, gives the -ene H2C=CH2. Polymerization of the -enes is the next step. Via another condensation reaction, a poly-eth-ene appears thusly: H2C=CH|HC=CH|HC=CH|HC=CH|HC=CH|HC... & etcetera.
ionic bond
Adhesive glue sticks to many surfaces and as the carrier dries, it will bond to the surface more permanently
