ARADUR® 115-3 X 70

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

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

Reactivity increases throughout the Aradur 115-3, 125-3, 140-3 hardeners. The degree of sensitivity to high atmospheric humidity increases in proportion with the amine content.

In combination with liquid or (preferably) solid epoxy resins or their solutions, such as Araldite GZ 7071 X 75, Aradur 115-3 X70 is suitable for the formulation of cold-curing, solvent-containing coatings, for application to steel and mineral substrates. Its main areas of application are in ship- building, anti-corrosion protection and the construction industry.

The mix ratio of Araldite GZ 7071 X 75 to Aradur 115-3 X70 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 115-3 X70 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. Keep this product from heat or ignition sources. Sometimes it happens that the typical yellow to brownish color of the hardener Aradur 115-3 X70 shows a greenish effect. Shelf life (at storage temperature between 2 - 40°C) (see expiry date on original container) - several years
