PU-M2: Polyurethane Foam Sealant
Description: Polyurethane (PU) Foam
It is a one-component, moisture-curing, multi-purpose polyurethane foam filled elastic sealing material. Polyurethane foam sealant is a special polyurethane product in which a polyurethane prepolymer, a foaming agent, a catalyst and the like are filled in a pressure resistant aerosol can.During the construction, the aerosol-like colloid is sprayed to the part to be applied through a matching gun or a manual nozzle to complete the molding, foaming, bonding and sealing processes in a short period of time. The cured foamed elastomer has excellent properties such as bonding, waterproofing, heat expansion and contraction, heat insulation, sound insulation and even flame retardant (limited to flame retardant type), and is widely used for building door and window seams, component expansion joints and filling of holes, seal.
Brief Introduction
Application Instruction
1. Remove the dirt and grease on the surface of the substrate, and spray the area to be filled with a little water mist.
2. It is used in the temperature range of 0 °C ~ 40 °C. If it is used in the cold season, in order to ensure the use effect, it is recommended to preheat the tank in a 30 °C environment.3. Shake vigorously for up to one minute before and after construction. Keep the tank in an inverted state during construction.
4. After the construction of each tank is completed, please clean the threaded part of the glue gun with special cleaning agent. After each continuous construction, please clean the whole gun and tube with special cleaning agent, to avoid cured blockage.
5. Repair and cutting should be carried out after the foam is fully cured. Attention: to cut the foamed skin will reduce the foam strength and reduce the sealing and waterproofing effect of the foam.
6. This product is not resistant to UV rays. It is recommended to cover and coat further.
