Description
PHS Airtight Foam
PHS Airtight Foam is and airtight expanding foam, specially developed to form an airtight, thermal and sound insulating interface between construction components.
•Heat Insulating
•Sound Insulating
•Highly Elastic
•Airtight
Properties
•Adheres to all common building materials, with the exception of polyethylene, silicone, oils and greases, mould release agents, etc.
•Processed at temperatures from +5°C to +30°C.
•Hardened foam is elastic, predominantly closed-cell, rot-proof, moisture-proof, temperature-resistant from -50°C to +100°C.
•Resistant to aging, but not to UV radiation.
•Offers excellent thermal and sound insulation values.
Processing
•The adhesive surfaces must be free of dirt, dust and grease.
•Slightly moisten the building connection joint with a water spray.
•The optimal processing temperature is +20° C to +25°C.
•Shake the can thoroughly before use.
•Fill the joint no more than halfway, because the fresh foam expands to 2-3 times the initial volume.
•Foam layers thicker than 5cm in several steps and allow each layer to harden.
•Additional moisture in the substrates accelerates and supports the curing of the foam.
•After applying each layer of foam, it’s recommended to moisten all joints.
•Insufficient supply of moisture or excessive moisture can lead to unwanted shrinkage of the foam.
•Never press the partially hardened foam into the joint.
•Remove fresh foam stains immediately with foam cleaner. This can only be done in the tack-free period. You can only remove hardened foam using a special cleaner or by mechanical means.”
