IDH is the acronym for International Data Harmonization, it is used as the unique identifier for all Henkel products - think of it as a part number.
The IDH of each product can be found on the product label as well as all product documents.
A 5-digit part number is the old LOCTITE® part number (item number). An IDH number (International Data Harmonization) is the corresponding new Henkel part number associated with the LOCTITE® item numbers. It is a global numbering system, generally composed of 6-digits with some exceptions.
The information is not public. You need to call customer service to get the total shelf life of any product.
Refer to the technical data sheet (TDS) for any product storage information.
An adhesive has “fixtured” when the bond is strong enough that the assembly can be handled without compromising the longterm strength of the adhesive. On a lab scale, fixture time is equivalent to the time required for 1” wide lap shears bonded with a ½” overlap to support a 3 kg weight in shear mode for at least 5 seconds. For CA´s, this time is usually seconds. Full cure is achieved when the adhesive has reached its highest bond strength – for CA’s this is typically 24 hours.
If a substrate is dirty, your bond is only as strong as the adhesion of the contaminant to the part, not the adhesive to the part. Contaminants can come from machining, protecting, handling, manufacturing, facility surroundings, and even from cleaners used previously that have left a film. Just a slight oil film left behind on a substrate can reduce adhesive performance by as much as 60 percent.
What type of strengths is being desired? We have adhesives that have tensile strengths of 8,000 psi or higher. We also have adhesives that have superior impact and peel strength… make sure you know what type of force you are looking for.
The requirements need to be defined to determine the nature of flexibility required.
Henkel products are available in different viscosities, strength, and other qualities that fulfill most requirements. We would have to look at the requirements of the application to find the right fit.
Viscosity measures the ability of a fluid material to resist movement.
The ability of an adhesive to withstand planar stress, when the substrates are pulled in opposite directions.
