Mapei Adesilex PG4 – Two component adhesive for structural bonding
Mapei Adesilex PG4 – Two component adhesive for structural bonding. Adesilex PG4 is a two-component adhesive based on epoxy resin, fine-grained selected aggregates and special additives blended according to a formula developed in Mapei’s own Research & Development Laboratories. Unlike Adesilex PG1 and Adesilex PG2, two-component thixotropic epoxy adhesives use for structural bonds, this product is characterised by its extended workability time. This property makes the product easier to use, even at high temperatures. Adesilex PG4 is also characterised by its low viscosity and, as a result, offers good wetting of the substrate. This makes it easy to apply with a spatula on horizontal surfaces, vertical surfaces and on ceilings without dripping, due to its high thixotropy. After preparation, Adesilex PG4 hardens in 5 hours (at +23°C) through chemical cross-linkage without shrinking. The composite obtained is characterised by its high bonding properties and by its considerable mechanical strength. Adesilex PG4 can be applied even on very damp surfaces as long as there is no standing water. Adesilex PG4 meets the requirements defined by EN 1504-9 (“Products and systems for the protection and repair of concrete structures – Definitions, requirements, quality control and evaluation of conformity – General principles for the use of products”) and the minimum requirements claimed by EN 1504-4 (“Structural bonding”).
Mapei Adesilex PG4 Uses
Adesilex PG4 is particularly recommended both for bonding synthetic braces used in waterproofing applications and for repairing, sealing and bonding elements in concrete, reinforced concrete, metal and natural stone.
- Waterproofing wide joints by bonding pre-formed straps (PVC, Hypalon, Mapeband and Mapeband TPE)to the concrete.
- Rigid structural bonding of prefabricated concrete elements.
- Sealing large cracks in industrial floors subject to traffic.
- Bonding slabs and pipes in concrete and fibre-reinforced concrete.
- Bonding steel to concrete.
- Bonding metal or TPE drains (Drain Front)
