Glossary and Common Properties

About room temperature cure The most common cure type is one-part moisture cure. There are several types, depending on reactive by-products (e.g., deoxime type and dealcohol type). There also are two-part condensation cure types in which curing starts from the surface exposed to air towards the deep section, and its cure speed depends on the absolute moisture. There-fore, although it depends on the size of the substrate, this cure type is not appropriate for bonding larger surfaces.

Pattern diagram of condensation reaction (an example of dealcohol type)

Storage recommendations Storage requirements differ for each product.• Products to store in a cool, dark place: We recom-mend storing products in a cool, dark place, except forthose that require cold storage or refrigeration.

• Products requiring cold storage or refrigeration: As arule, for one-part addition-cure products requiring coldstorage, store between 0 and 5°C; for one-part addition- cure products requiring refrigeration, store between -25and -15°C.

About low-molecular-weight siloxaneWhen a micro-relay, micro-switch or similar micro-elementis in airtight or semi-airtight conditions, ingredients emitted from silicone materials can insulate contact points fromelectric energy, which may cause continuity or contactfailure. These emitted ingredients, called low-molecular- weight siloxane, are shown below. Low-molecular-weightsiloxane reduction grades contain reduced amounts oflow-molecular-weight siloxane.

Structure of low-molecular siloxane

About heat cure To cure addition-cure products by heating, place them in an oven or on a hot plate set at a specified temperature for a certain duration. The duration must be determined based on the heat capacity of the materials used.

Pattern diagram of addition reaction

About cure inhibition Certain materials, chemicals, curing agents and plasticizers can inhibit the cure of addition-cure adhesives. Most nota-ble of these include organotin and other organometallic compounds; silicone rubber containing organotin catalyst; sulfur, polysulfides, polysulfones or other sulfur-containing materials; unsaturated hydrocarbon plasticizers; and some solder flux residues (e.g., flux, amines, vinyl chloride and sulfur vulcanization rubber).
