The AggreBind polymer has been developed and amended for use in the Construction industry – AggreBind Test Reports
1) Adhesion; excellent to various stones; marble; cement; slate; tested using cross-hatch tape test. The coating is scored using a sharp knife or special tool; Scotch tape applied and pulled off. An estimation of the amount of coating remaining is made. This is a standard test for paint lacquers.
2) Longevity; this is a polymer and therefore will not degrade readily. Coatings have been exposed to air and light for many years without any signs of deterioration.
3) UV resistance: No observed deterioration has been observed. In addition when used in construction the underlying layers are protected by the surface minerals preventing UV damage.
AggreBind Test Reports: ASTM D4429 AggreBind road test Quito
4) Environmental: The polymeric content has a molecular weight of much greater than 1000 and is therefore deemed to be not bio available. It is therefore considered to have a minimal impact on the environment.
5) Surface abrasion: Good resistance as a film; this will be enhanced by the mineral content in construction.
6) Surface spills: 2 coats of polymer allowed 48 hrs to dry. 24 hr spot test
Petrol: film slightly dulled; no effect on film integrity
Light mineral oil: no effect
15W/50 Motor oil: no effect
Hydrochloric acid: film dulled and slightly swollen; adhesion to tile reduced
Phosphoric acid: film destroyed salt resistance: “Rock Salt” = sodium chloride (NaCl), this should have no effect on a dry film of AggreBind
In the AggreBind Test report – The only chemicals that would destroy a dry film of AggreBind are strong acids and bases (pH above 10), petrol and engine oil had no effect on a dry film of AggreBind (note: tests were carried out without tracer or carbon black, we are confident that the addition of the tracer and carbon black does not negatively impact on the chemical resistance of AggreBind).
*temperature resistance: dry film of AggreBind will start to burn at temperatures above 300C.
7) Compatibility: This is an anionic dispersion and therefore will be coagulated by cationic surfactants, acids and high ion concentrations; particularly of trivalent metal salts.
8) Various other water miscible chemicals can be added without causing undue problems especially if pre-diluted.
9) Cured film recovery and memory characteristics: This is a styrene-acrylate polymer and not an elastomer. The film is flexible.
