Sika Boom®-180

Polyurethane foam

15 months from date of production

Store properly in the original, unopened, undamaged, sealed packaging. Store in an upright position, in dry conditions, out of direct sunlight and at temperatures between 41 °F and 77 °F. 

R-value 4.0 per inch

Not permanently UV stable (for best results, the cured foam may be painted or coated for outdoor applications)

12 fl. oz. can yields 28.8 linear ft. of foam (1/4 in. x 1/4 in. bead)

The substrate must be clean, sound, firm, free from oils, grease, dust and loose or friable particles. Paint, cement laitance and other poorly adhering contaminants must be removed. Sika Boom®-180 will adhere without primers or activators to most building materials such as wood, concrete, brick, metal or aluminum. For non-conventional substrates a preliminary adhesion test is recommended.

1. Pre-dampen the substrate with clean water. This ensures that the foam cures properly and also prevents unwanted foam expansion.
2. Shake the can well for a minimum 20 times before use. Note: Repeat shaking after long interruptions of use.
3. Remove the cap from the can.
4. Screw the nozzle firmly onto the thread of the valve without pressing the trigger or the valve.
5. IMPORTANT: To ensure proper flow, hold the can upside down while dispensing. Dispense the foam by pressing the trigger. Note: The amount of foam extruded can be regulated by applying more or less pressure on the trigger.
6. IMPORTANT: Allow each layer to expand and harden sufficiently before pre-dampening with water again for next layer application. Fill deep joints in several layers. Note: Fill voids / cavities only partially as the foam expands during curing. Note: Small gaps can be filled using an extension tube, this will however reduce the foam flow rate.

Re-Usable Straw: To ensure that the straw can be re-used: 1) set the can upright and 2) while it is still full of foam, fold back the straw over itself and slide open end onto the plastic tip located above the trigger to a depth of a 1/4 in. This will keep the straw air-free. When you are ready to re-use the product, simply shake the can, unfold the straw, and proceed with spraying. 

Uncured foam can be immediately removed from tools and finished surfaces using an approved solvent (e.g. Acetone, MEK, or Xylene). Cured material can only be removed mechanically. For spillage, collect, absorb, and dispose of in accordance with current, applicable local, state, and federal regulations.
