SikaDamp®-110
Heat fusible bitumen foil with antiblocking agent
SikaDamp®-110 is a standard heavy layer, flexible bitumen foil for sound deadening and sound damping applications on steel substrate. The bitumen heavy foil is filled with mineral material and polymers. SikaDamp®-110 is covered with a water based antiblocking agent and equipped with a polyamid hot melt adhesive. The odor of SikaDamp®-110 is negligible in household appliances in operation up to 80 °C. At higher temperatures, a slight bitumen odor may be perceptible temporarily.

Areas of Application
SikaDamp®-110 was initially developed for the noise damping in the field of household appliances, such as dishwashers (steel tub), washing machine, tumble dryer and small appliances. It can as well be used in other industrial fields, where damping with high density bitumen foils is required.This product is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed ensuring adhesion and material compatibility.

Application
Surface preparation
Surfaces must be clean, dry and free from grease, oil, water and dust.
Application
During application, the hot melt adhesive must reach 115 °C for a period of at least 30 seconds.
It is common practice in the industry to heat the bitumen material from the bitumen side in order to soften the bitumen material first and to achieve a full surface contact of the mat before the hot melt adhesive is activated.
For information regarding typical loss factors, see diagram 1. The layer structure is shown in figure 1.

STORAGE CONDITIONS
SikaDamp®-110 has to be stored dry and protected from UV light. The storage temperature is between 0 °C and 35 °C. Consider, that at temperature below 15 °C the bitumen starts to get brittle and can break. Therefore, if products are sourced from a cold storage it must be handled with care.
Ensure that the product has reached the defined application temperature before it is applied. This might be realized by storing the parts for 24 to 48 hours prior application at the assembly line.
Note: Storage outside of standard conditions can affect the shelf life.
