IROSTIC® S 9827

Preparation
IROSTIC ® adhesive systems should be dissolved in closed dissolvers. The time required depends on the solvent used and on the construction features of the equipment. Straining the finished solution is recommended.If fillers have been added to the system, then additional straining may be essential.The adhesive solution may be applied to prepared (roughened, solvent wiped) surfaces:

• • Manually, via brush, roller or spatula
• • Mechanically, via roller, knife, spray gun or air gun

The adhesive should be applied to both surfaces.Surfaces must then be air dried until the solvent has evaporated. This takes between 30 and 60 minutes, depending on the quantity applied. Excellent adhesion can be achieved when the surfaces are thoroughly
dried. Dry surfaces should then be pressed together following the required activation procedure to create a stable bond.

Activation
IROSTIC ® adhesive systems require heat activation. If used as a two- component adhesive, activation must be carried out within a 6 to12-hour period. Activation can take place under infrared light or by using other sources of heat.

Pot Life
Where IROSTIC ® systems are used as a two-component adhesive, pot life must be considered. Even at room temperature, the crosslinking reaction starts the moment the crosslinking agent is added (ie: IRODUR®).The viscosity of the solution gradually increases over 8 to 12 hours.

All IROSTIC® products must be stored in a cool and dry place. If stored correctly, under adequate conditions, products can be expected to remain stable for a minimum of six months.
