Adhesive for Polypropylene

Adhesive for Polypropylene

Adhesive for Polypropylene

I am looking for a durable weather resistant glue to use on corrugated polypropylene, anyone have some good recommendations? (More info below)

I would need a glue that can withstand lap-shear and t-peel forces. I would also prefer an easy application and quick set time as these are assembled by hand.

I have tested a few hot glues(recommendation does not need to be a hot-melt) and some work very well at room temperature but fail in cold and hot temperatures, many of my products are used in the shipping industry where they will be subject to temperature extremes.

RE: Adhesive for Polypropylene

3M makes many adhesives for high energy plastics, that would be my first place to search.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

RE: Adhesive for Polypropylene

This 'low energy bonding' white paper from 3M might be worth a read. Link

RE: Adhesive for Polypropylene

Thank you epoxybot, I stand corrected. Low energy is the term to search. It's tough getting old!

Your welcome, I sometimes get intrigued by come new product while confusing surface energy with surface tension and upon making the realization of my error, discover I have been reading a snake oil pitch dressed up as a magazine article.

RE: Adhesive for Polypropylene

I recall plasma treatments can be used to damage just the surface of certain materials to allow adhesive bonding.

Found this link: http://www.pvateplaamerica.com/materials/polymers-... Not an endorsement; it just has an explanation.

RE: Adhesive for Polypropylene

Surface energy and surface tension are essentially the same thing. Surface energy is used for solids and surface tension is for liquids. A liquid with a surface tension of 40 dynes/centimeter has a surface energy of 40 ergs/square centimeter.

White Paper - Effects of AIA Quick Guide to UL 489 or UL 1077
The function of a circuit breaker is to provide overload (thermal) and short-circuit (magnetic) protection to a circuit and its downstream components. A circuit breaker functions like an airbag in a car, protecting circuit components and people by tripping the circuit to interrupt the current flow if it detects a fault condition in the control system.

White Paper - Guide to Integrate Large-Format Additive
As with any new technology, getting into large-format 3D printing begins with investigation. The first question may be a simple one: what does “large-format” mean? For 3D printers, “large” is a relative term. Many extrusion-based (FFF) 3D printers are referred to as desktop machines, because they fit on table space. Some of these have very respectable build volumes – but when it comes to “large-format,” the machines will need their own dedicated floor space. Large-format 3D printers have significant build volumes and are most often found in professional settings, like manufacturing facilities and R&D centers. Download Now
