Product Description
SealBoss 2810 SilFoam is a fast-foaming, solvent-free, two-component urea-silicate expansion foam system with outstanding sealing and cavity filling properties. SealBoss 2810 SilFoam reacts with or without the presence of water.
The product offer predominantly closed cell foam cells and good chemical stability. To achieve most satisfying and permanent results, a combination of SealBoss 2810 SilFoam with other systems of our product line may be advised.
Ask your SealBoss ® technician for details. The product is for professional use.
Installation Guidelines
SealBoss 2810 SilFoam components are injected in the proportion of a 1:1 by volume ratio using a two component injection pump equipped with a static in-line mixer nozzle.
Component A must be stirred separately and thoroughly with a low-speed paddle mixer before use immediately before application. The prepared 1:1 ratio material is to be injected with the SealBoss IP2C Gel Injection Pump with a silicate mixing tube of 8mm diameter, and 500mm length.
A static mixer blends both components and injects them into the mountain side, rock or soil. The curing reaction time of the urea-silicate foam formulation is significantly depending on temperature.
It is recommended that component A be mixed separately with a low speed mechanical mixer at 300 rev/minute max.
Store the components before processing at a minimum temperature of 15-20°C for at least 12 hours in order to reach the recommended processing temperature of between 15°C and 30°C.
