Applications & Uses
- Applications
- Coating Type
- Field of Application
Polem A JS is designed to be used as a solid, elastic joint sealant and pore filler material for concrete elements, especially suited for aqueous environments like drainage and sewage joints.
- Typical Areas of Installation
- Wastewater pipes
- Flooding reservoirs
- Flooding channels
- Fish tanks
- Substrate Preparation
All substrate must be structurally sound, clean and dry and free from oil, grease and loose material and other contamination which might impair adhesion. The tensile cohesion of the substrate should exceed 1,5 MPa. Polem A JS should be applied when substrate temperatures are constant or falling. The curing reactions are influenced by the ambient, material and substrate temperatures. Low temperatures lengthen the pot life, open- and curing times. High temperatures shorten pot life, open- and curing times. The temperatures should not fall below the minimum stated until the material is fully cured.
- Application
The B-component is poured into the container with the A-component. Directly after pouring the two components together, they are mixed for several minutes until homogeneous with a suitable stirring devise. The reactive paste is then poured into the cavity.
