Technical Data Sheet
General Preparation:
The temperature of the working area should be between -5°C (23°F) and 35°C (95°F). The temperature of the product should be between 5°C
(41°F) and 30°C (86°F). When working in cold conditions, can should be stored at room temperature for at least 12 hours before use. Shake can
vigorously before use for 30 seconds (15-20 times minimum). Screw the foaming straw to the valve. Shake intermittently during use.
Application:
Holding can upside down, press the trigger which controls outflow rate of the foam. Dispense the foam sparingly, filling the joint initially by half to
avoid excessive overflows. Shake can regularly during use. Slight misting with water can speed cure. Foam can be trimmed with a knife after an
hour. Foam will be fully cured in approximately 24 hours. It is recommended foam be protected from UV radiation by a protective covering or
coating such as paint, plaster, mortar, etc.
Note: Ambient temperature and humidity can affect foam curing and maximal joint width. In dry conditions, to get the best foam structure and
properties, it is recommended to fill gaps and joints in several layers by the application of smaller foam strings (up to 3 inches thickness). At very
dry conditions, the foam may be brittle after hardening. This brittleness is a temporary effect.
Clean-up:
Clean tools and uncured foam residue immediately with acetone. Cured foam must be carefully cut away with a sharp-edged tool.
Product must be stored vertically, not horizontally on its side.
Note: When storing foam dispensing applicators with foam cans attached, be sure to store the tool with the can valve pointing downwards. Storing
the can upright may cause propellant to leak and the foam applicator to become inoperative.
Store in a cool, dry place. For maximum performance and shelf life, store between 5°C (41°F) and 25°C (77°F). The product can be stored for a
maximum of 1 week at -20°C (-4°F). Do not store below -20°C (-4°F), below this temperature product valve may spontaneously open resulting in
leakage.
Containers are under pressure. Do not expose to open flame or temperatures above 49°C (120°F). Do not store under direct sunlight. Excessive
heat can cause bursting and premature aging of components resulting in shorter shelf life. When containers are empty, vent off any excess
pressure. DO NOT discard empty can in garbage compactor. DO NOT incinerate. DO NOT puncture, cut or weld container.
Recommended method of disposal for unused product: Vent off excess pressure and dispose of in an appropriate waste receptacle. Dispose
of according to provincial and federal governmental regulations.
STORAGE & DISPOSAL
DANGER! EXTREMELY VAPOR MAY CAUSE FLASH FIRE. VAPOR AND SPRAY MIST HARMFUL, OVEREXPOSURE MAY CAUSE
LUNG DAMAGE. MAY CAUSE ALLERGIC RESPIRATORY AND SKN REACTION. CONTENTS UNDER PRESSURE.
DANGER! Contains polyurethane prepolymer, methylenediphenyldiisocyanate, dimethylether and hydrocarbon propellant mixture. Do not
use near sparks, heat, or open flame. Vapors will accumulate readily and may ignite explosively. Ventilate area during use and until all vapors
are gone. DO NOT SMOKE. Extinguish all ignition sources. If burned, dried foam may release hazardous decomposition products. Dried
foam may be combustible if exposed to flame or temperatures above 240°F. Avoid prolonged exposure to sunlight or heat from radiators,
stoves, hot water and other sources of heat that may cause bursting. Do not puncture, incinerate, burn, or store above 120°F. Do not discard
empty can in garbage compactor. Gives off harmful vapor of solvents and isocyanates. Do not use if you have chronic lung or breathing
problems, or if you have ever had a reaction to isocyanates. Use with adequate ventilation. Use appropriate respiratory protection when
potential to exceed exposure limits exists. If you have breathing problems during use, leave the area and get fresh air. If symptoms develop
or persist, call a doctor or obtain medical treatment; have this label with you. EYE AND SKIN IRRITANT. Avoid contact with eyes and skin.
Prolonged or repeated skin contact may lead to sensitization and dermatitis. Wash hands after using. Do not swallow. Intentional misuse
by deliberately concentrating and inhaling the contents may be harmful or fatal.
FIRST AID: For eye contact flush with water for 15 minutes. Call a physician if irritation develops and persists. For skin contact, wipe off
excess uncured foam with a clean rag or paper towel immediately. Get medical attention if irritation develops and persists. If affected by
inhalation, remove to fresh air and contact a physician. If swallowed, do not induce vomiting. Call a physician or Poison Control Center
immediately. KEEP OUT OF REACH OF CHILDREN.
