Is There An Air-curable Version of Liquid Polyethylene?

Hi,

no polyethylene is aircuring.

It is made by high pressure polymerisation of ethylene using catalysts to determine the molecular weight.

Chemically these PEs are long chain paraffines.

You can melt these unless mostly linear.

You can crosslink the molecules by pressure and catalysts or by radiation so the resulting material will no longer melt but decompose on being heated.

If you really want a room temperature curing plastic this can be epoxies, polyesters, silicones and polyamide (laurylamide)

RHABE, I didn't understand your comment: "You can melt these [long chain paraffines] unless mostly linear". Did you mean branched or cross-linked???

It doesn't matter.

Beware of heating polyethylene. Though chemically very similar to candle-wax, the presence of molecules with much longer chains means that with increasing temperatures by the time it gets fluid it may have already started to decompose, either in contact with the heating surface or with the air around it.

No, there are no fixed and fast rules. Field Trials are the only way forward!

Foster Products has a product called "spray poly":

It is sometimes used to seal and isolate asbestos abatement work areas from adjacent areas during the work.

About 20 years ago, I worked with a similar product with the same name, that was manufactured by a company by the name of "Isotek".

Be forewarned, (unless this Foster product is a markedly different formulation), after the spray application, during its drying/curing period, the product emanates a strong ammonia-like odor.
