Crosslinkers / Curing Agents / Hardeners. Crosslinking boosts the thermal stability and mechanical properties of the polymer. Substances/ mixture of substances that are added to a plastic composition to assist crosslinking and enhance the curing reaction are called crosslinking/curing/ polymerization additives.
FX-752 Epoxy Bonding Agent. FX-752 Epoxy Bonding Agent is a solids, two-component, moisture-tolerant epoxy system designed to increase the bond between freshly-placed repair mortars or concrete mixes and existing concrete. 03 01 00 Maintenance of Concrete.
HX-752 Dynamar™ Bonding Agent for Ammonium Perchlorate. A bonding agent is a substance used to improve the mechanical properties of a composite system by increasing the adhesion between the filler particles and the rubbery matrix. Effective with Ammonium Perchlorate in butadiene binders. HX-752 releases virtually no ammonia and can be used with a short mix cycle. Manufacturer: 3M
There are three types of curing agents, namely: curing ag ents that react with the surface upon which they are applied to facilitate hardening; catalytic ag ents that do not react with the material surface; and initiator ag ents that only beg in the necessary hardening reactions …
3. Uses: HX-752 is a good bonding agent, which has been used for over 20 kinds of military composite propellants. It has been also used widely as the bonding agent of polymer materials to improve the mechanical properties. 4. Safety instructions: Toxic by skin. Operation carefully must be installed with rubber gloves to avoid contacting with skin, eyes and clothing.
Properties: RICHEST RE is a highly active cross-linking agent, Used in the adhesives made by hydroxyl polyurethane, natural or synthetic rubber, it has excellent bonding strength in rubber and cab be used in resin, antioxidant, plasticizing agent, pressure-sensitive etc. It can be used as crosslinker instead of BAYER's Desmodur RE.
Storage The recommended storage temperature for HX-752 is -18 °C (0°F), and at this temperature the shelf life is at least one year. At higher temperatures HX-752 is generally found to slowly homopolymerize or rearrange to the oxazoline form. Shelf Life One year under recommended storage conditions. Packaging One-pound, eight-pound and 44-pound units.
Dec 18, 2017· Accelerated amidoamine. Acts as a moderately reactive room temperature curing agent. Possesses good mechanical and chemical properties. Compositions based on EPON™ Resin 828 and EPIKURE 3072 cure well in the presence of moisture and form a strong bond to damp concrete as well as other structural materials.
