Epoxy

 

Araldite® 2015  Germanischer Lloyd (GL) certified, Det Norske Veritas Approvals
Araldite® 2015 is a two component, room temperature curing paste adhesive, which gives resilient bonding and sealing on metals, composites and plastics.

Araldite 2015 is particularly suitable for SMC and GRP bonding and when formulated for specific applications it forms durable, elastomeric joints that are water tight andm weather resistant, making ideal for all types of marine applications.
Araldite® 2015 has been awarded the internationally recognised Germanisher Lloyd and Det Norske Veritas Type Approvals for the construction of commercial and military marine craft and aluminium fast ferries. This product can be now used for the appropriate bonding applications on any boat, ship or ferry without having to apply for individual appovals.

Araldite® 2031

  • Good moisture resistance
  • Extremly tough and resilient adhesive
  • Long pot life, ideal for large composite part assemblies

Araldite® AW4858/ Hardener HW4858 is a two-component, room temperature curing, black coloured epoxy adhesive paste of high strength and toughness. Performances can be enhanced by post-curing at elevated temperature. It is suitable for bonding a wide variety of metals, and especially designed for bonding composites.

Araldite® AW 4859/HW 4859
Two component epoxy adhesive system
Specific properties

  • Very high lap shear
  • Bonds a wide variety of materials (metal, composite and thermoplastics)
  • Temperature resistant up to 140°C
  • Extremly tough and resilient adhesive

Araldite® AW4859/ Hardener HW4859 is a two-component, epoxy adhesive paste of high strength and toughness.
Performances can be enhanced by post-curing at elevated temperature. It has been designed to perfectly bond onto composites , especially CFRP but it is suitable for bonding a wide variety of metals, ceramics and many other substrates in common use.

 

Methymethacrylate

 

Araldite® 2022
Toughened, two component methacrylate adhesive
Specific properties

  • Excellent adhesion to a wide variety of plastics, composites and metals
  • Excellent resistance to gasoline and oil
  • Tolerant to "not quite perfect" pre-treatment
  • Fast curing
  • Joint filling up to 4 mm

Araldite® 2022 is used to fix together different components of the yacht, which involves the bonding of dissimilar substrates, such as polystyrene, aluminium, steel and various engineering plastics. Araldite 2022 has a good resistance to the harsh environmental conditions encountered at sea, as well as its excellent bonding properties to the wide range of substrates involved in the construction of racing yachts. It requires only minimal pretreatment.

 

Other products

 

PUR

These two-component adhesive composed of the polyol component (A) and the isocyanate component (B) have to be mixed in a certain proportion and process. The adhesives can also be obtained as flame retardant systems. The adhesive layer of 2-component polyurethane adhesive is tough to elastic-flexible after curing, depending on the raw materials. Our systems are supplied with a pot life of 2-120 minutes, available in viscosities from thin to highly viscous. PUR 2-component adhesives are ideal for bonding surfaces for vehicle superstructures, facade elements, as well as in shipbuilding.
Other suitable applications include high-quality assembly bonding, plastic bonding, corner angle bonding, as well as its use as a potting compound or as adhesives for SMC components.

  • Betaforce™, semi-structure and high modulus
  • Betamate™, flexible and semi-structural
  • Betalink™ K2

Environmentally friendly spray adhesives

Northstar spray adhesives have a very low content of volatile organic compounds and are free of air pollutants. Through a user-friendly technology no spray mist comes up. The spray adhesive is mobile applicable and suitable for various materials such as wood materials, composites, many plastics including polystyrene and other materials. Applications are found in upholstered furniture and kitchen but also for automotive interior trim, as indeed in the whole automotive applications. Ship construction and marine applications are of particular interest because the adhesives have a very good water and moisture resistance. The process is quick and easy. Due to the low adhesive required, costs can be saved.

  • StarStuk™ Chlorine free spray adhesives
  • NauticGrip™ Adhesive for hybrid applications
 

Adhesive pastes

Multi-purpose adhesive pastes
These are suitable for non-structural fiberglass applications. The comprehensive range includes a number of adhesive pastes based on ortho and isophthalic acid for all application areas.
Benefits

  • Excellent handling characteristics
  • No addition of resin for a good flow necessary
  • Different densities, different gel times
  • Color indicator, indicating the addition of the catalyst
  • Low shrinkage
  • Variety of substrates - fiberglass, wood, steel or aluminum

High-performance adhesive pastes
These are formulated with the addition of the unique urethane acrylate technology to improve the fatigue resistance compared to standard adhesive pastes. This series of adhesive pastes can be used if a higher performance than with a standard adhesive paste is required, and if structural adhesives are too specified. The product series also represents an alternative to vinyl ester adhesive pastes.
Benefits

  • DNV approval
  • Low shrinkage
  • Shear strength of 9,8 MPa
  • Elongation at break of 2,8% - 3,3%
  • Density of 1,2
  • Colour indicator

Marine applications
Bonding of double-walled outer shells
Attachment of foam stringers on GRP boat hulls
Bonding wood parts on GRP laminates
Filling of oars

  • Crystic®

Structural adhesive for bonding of fiber-reinforced plastics
