Field of application
Foam is used for installation of doors and windows, creating soundproof screens, insulation and fixation of tubes, filling of holes and gaps, fixation of wall panels and roof stones, and for thermal insulation.
Expansible Foam
One-component polyurethane foam is an air humidity curing prepolymerized mixture in an aerosol can. Cured foam is a good temperature and sound insulator, and has strong adhesive properties. Great results at higher temperatures. Adheres well to most building materials, with the exception of Teflon, polyethylene and silicon surfaces. Cured foam is sensitive to UV-light and direct sunlight.
Safety Regulations
Can contains diphenylmethane 4,4-diisocyanate. Dangerous when inhaled. Irritates eyes, skin and respiratory organs. Inhalation of gas may cause allergy. In case of eye-contact rinse thoroughly with water and seek medical help. Do not smoke during work! Make sure that there is good ventilation, use protection means when necessary. Keep out of the reach of children. Detailed safety information is available on safety data sheet (SDS).
Application Instruction
Hold the foam can in upright position, turn the gun to the can by holding the gun handle with one hand, and turn the can with the other hand. Make sure that the gun is not pointed to other persons when turning it. The can must not be screwed to the gun with the valve upside down or by turning the gun on the can. After fixing the gun, shake the can well at least 20 times. The foam output can be adjusted by gun trigger. At low temperatures foam can must be warmed before work in warm room or water. Temperature of room or water must not exceed +30 °C.
Application Conditions
Air temperature during application between +5 °C and +40 °C, best results at +20 °C. Can temperature during application between +5 °C and +35 °C, best results at +20 °C. Surfaces must be clean from dust, loose particles and oil before foam is applied. Substrate should be moistened prior application as the foam cures due to the moisture. In case of multiple layer application repeat moistening after each layer. Cured foam can be painted.
Storage Conditions
Can must be stored and transported in vertical position. Store in a cool and dry place. Store at temperatures +5 °C - +30 °C. Aerosol can must not be stored at temperatures over +50 °C and in direct sun. Storage life 12 months.
Cleaning
Soft foam can be removed with acetone, cured foam only mechanically.
