ARADUR® 115 X 70

In combination with solid epoxy resins or their solutions for cold-curing, solvent-containing lacquers presenting the following features:

• Extremely long working times
• Non-tacky films after the pre-reaction
• Very good adhesion and flexibility
• Very good anti-corrosion protection.

Reactivity increases throughout the Aradur 100, 115, 125, 140 hardeners. The degree of sensitivity to high atmospheric humidity increases in proportion with the amine content. For applications under cold-damp conditions, we recommend Aradur 422 XW 70, 423 XW 60 and 424 XW 50 hardeners (pre-adducted polyamidoamine).

Along with liquid or (preferably) solid epoxy resins or their solutions such as Araldite GZ 7071 X 75, Aradur 115 X 70 is suitable for the formulation of cold-curing, solvent- containing coatings for application on steel and mineral substrates. Main applications in ship-building, anti-corrosion protection and the construction industry. 70% ARADUR® 115 hardener solution in xylene.

The mix ratio of Araldite GZ 7071 X 75 to Aradur 115 X 70 should be selected as 100:53 parts by weight. Deviations from this of up to 20 % are acceptable. In such cases a higher proportion of Aradur provides increased flexibility and adhesion, while improved chemical resistance is achieved with a reduced proportion of Aradur.

Aradur 115 X 70 should be stored in a dry place, preferably in the sealed original container, at temperatures between 2 and 40°C. The product should not be stored exposed to direct sunlight. Sometimes it happens that the typical yellow to brownish color of the hardener Aradur 115 X 70 shows a somehow greenish effect. Shelf life (at storage temperature between 2 - 40°C) (see expiry date on original container) - several years
