(Three Bond ) is. Three Bond Series (curing agent for epoxy resin), and the. of aliphatic amine. The curing of epoxy resin by amine curing agents Resins that have been cured using aliphatic amines are strong, and .
The following structure shows a. Isophorone diamine (IPD, Structure ) is a unique type of curing agent in that its structure contains both a primary cycloaliphatic amine group and a primary.
Stoichiometry : The number relationship between reactive groups in a reaction.
For example, an article can comprise an amine-epoxy composition which comprises the contact product of an amine curing agent component and an epoxy component. Isocyanates are some of the leading occupational causes of respiratory disorders, predominantly asthma. Not yet available for Apple iPhone, but coming soon.
Epoxy Curing Agents BASF Intermediates
Adduction of hydrophilic polyetheramines has been used to create reactive surfactants, thus allowing reduction or elimination of un-bound surfactant additives, which may migrate over time and change performance Figure 3.
In yet another aspect, the M n is in a range from about to aboutabout to aboutabout to aboutor about to about

|The coatings of Examples exhibited very fast dry speeds, and outstanding impact flexibility.
For example, in formula Ithe fact that R 1 is bonded to two other groups is consistent with this description of an alkanediyl moiety. Processing Requirements Stoichiometry and Mix Ratios As a general rule, use of a stoichiometric ratio of amine hydrogen to epoxide groups will, when fully reacted, ensure maximum stability of the product. As indicated in Table 8, increasing the ratio of epoxy groups relative to amine hydrogens increased the dry time as measured by thin film set time, but yielded increased hardness and improved appearance as measured by gloss.
The reactor was cooled to room temperature and depressurized, and the reaction product was filtered to remove the catalyst. Additionally, advanced dihydric phenols of the following structure also are useful in the present invention:.
Aromatic amines were widely used as epoxy resin hardeners, due to the excellent end properties when mixed with a parent resin.
All amine functional curing agents, for example, aliphatic polyamines and their. Amine curing agent technology for curing polyisocyanate AliphAtic. Amines. Wide range of products with differing properties.

The curing agents sold under the Baxxodur® trademark, such as polyether amines, aliphatic and cycloaliphatic amines, differ in molecular structure, basicity and.
These resins typically display low viscosity at room temperature mPa.
When using latent hardeners, the epoxy resin and hardener may be mixed and stored for some time prior to use, which is advantageous for many industrial processes.
They are also sold in boat shops as repair resins for marine applications. In general, epoxies are known for their excellent adhesion, chemical and heat resistance, good-to-excellent mechanical properties and very good electrical insulating properties.
