Reactive one- and two-component systems are chemically curing adhesives and are liquid or pasty at room temperature.
The Jowapur® series of Jowat provides a wide range of 1-C PU prepolymers with specific processing parameters, developed to meet different requirements: short processing times for a fast and flexible production, or long assembly times for large batches and for manufacturing big parts.
The two-component Jowat® SE polymers based on silane-terminated epoxy resin have been developed especially for applications which require a bond with a high resistance to ageing, a permanent resilience, as well as an elastic bondline. In addition, adhesives from this product group are often used by our customers for joining surfaces which are difficult to bond.

Reactive 1-C and 2-C systems provide the following benefits:

  • easy processing
  • broad spectrum of adhesion to different materials
  • high resistance to heat and water
  • good resistance to plasticisers as well as to many solvents
  • joint-filling foaming of 1-C PU prepolymers

Product series, characteristics and applications

Jowapur® 单组份聚合物

Basis: Polyurethane
Properties: One-component, moisture-curing prepolymer adhesives based on polyurethane from the Jowapur® series cure by crosslinking in a reaction with water or humidity. They are free of formaldehyde, have a lower application amount compared to other systems due to a solids content of 100 %, and are hardening within a few minutes at room temperature.
Application: (Load-bearing) glulam, different assembly applications in workshops, applications outside, sandwich elements
Packaging types: Drums, IBC, cartridges (pasty), bottles, canister 

Jowapur® 单组份聚合物

One-component, moisture-curing prepolymer adhesives based on polyurethane for load-bearing timber constructions

Jowapur® 双组份聚合物

Basis: Polyurethane
Properties: Two-component polyurethane prepolymer adhesives.
Application: Sandwich elements, outdoor applications
Packaging types: Drums, IBC 

Jowat® 1-C S polymers

Basis: Silane-terminated polymers
Properties: One-component S polymers, also called silane-terminated polyurethanes/polyether (STP/STPE), MS polymers or hybrid polymers, are moisture-curing adhesives and sealants with a low to medium strength. A major characteristic of these products is their elastic property. Due to integrated adhesion promoters, it is usually not necessary to pretreat the substrates. The curing reaction is triggered by water or moisture, starting on the exterior and continuing towards the centre. 1-C S polymers provide a blister-free bondline, even in joint-filling applications, and are free of isocyanates, solvents and silicones.
Application: Sealing and assembly operations, furniture and equipment manufacturing, automotive industry
Packaging types: Cartridges, hobbocks, drums

Jowat® 双组份环氧硅烷树脂粘合剂

Basis: Silane-terminated polymers/epoxy resins
Properties: Two-component silane-epoxy resin adhesives are a unique hybrid system. They couple the benefits of elastic silane-terminated polymers (MS polymers) with the high strength of epoxy resins. Bondlines with these chemically-curing 2-C systems harden evenly without any blisters, independent of the available moisture and the layer thickness. The adhesive can be processed within the pot life, and a deviation of up to 15 % from the ideal mixing ratio does not have any negative impact on the bond properties. 2-C SE polymers are characterised by excellent adhesion to metal, plastics, wood, concrete and mineral substrates, have joint-filling properties, and are not foaming. Due to these properties, they are ideal assembly adhesives and are used in many applications. 2-C SE polymers are free of isocyanates, solvents, plasticisers and silicones.
Application: Manufacturing of cladding, windows and doors, shipbuilding and vehicle production, as well as applications in the automotive industry
Packaging types: Cartridges, hobbocks, drums

Jowat® 2-C SE polymers

Jowat® SE polymers are two-component adhesive systems, which build a bridge between the powerful epoxy resins and the MS polymers with excellent adhesion properties.
