Rigidiser

500ml

An inorganic liquid hardening agent for ceramic fibre blanket and board. It produces a hard surface finish with increased resistance to mechanical abrasion and to gas flow erosion. Hardener can be applied by brushing, spraying or dipping.

Rigidiser will help the walls of the kiln made with blanket fibre from being too flaky.

APPLICATIONS PROCEDURE
Hardener is normally used diluted 50-50 with water and can be applied by brushing, spraying, or dipping. Spray operation should be carried out under well ventilated ,conditions, taking care to avoid breathing in the spray.
The amount needed varies with the type of application, and is dependent on variables such as Blanket density and the depth of treatment required. As a surface coating, 2.5 litres of diluted Hardener will cover 1m2, and 17 litres will saturate the same area of 25mm @ 128kg/m3 Blanket.
Drying procedure is not critical but 12 hours at 90 C is fairly typical. Natural drying is feasible but, in the case of through-hardened Blanket or Board, migration of Hardener to the material surface may occur.
