Spray adhesive INFUTAC (Clear) 500 ml

High strength Diatex infusion moulding spray adhesive specifically designed to hold reinforcing fibres in place during resin infusion process without affecting the surface finish.

• Adjustable spray cap
• Transparent for visible carbon fibre parts
• The nozzle cannot get blocked with the adhesive
• Used for resin infusion, vacuum moulding and RTM
• Provides superior layer fixation
• Safely bonds reinforcements to structural core materials
• Doesn´t affect the resin´s mechanical properties
• Low shrinkage in curing
• Fast bond

For bonding and shear-bonding a wide range of materials including:

• Plastics
• Fabrics
• Breathers
• Foams
• Lightwood (e.g. balsa)

INFUTAC is used for resin infusion, vacuum moulding and RTM. It will not interfere with the curing process of vinyl ester, polyester or epoxy resins: the adhesive is designed to ultimately become part of the polymer matrix.

Consumption per tin: 8-12 m²

Important note
Polychloroprene-based spray adhesives, such as Infutac and Aerofix, are generally less suitable for fixing the first fibre layer in the mold directly over the release agent. Spray adhesives are contact adhesives that adhere very well even to surfaces treated with release agents. It does not matter whether they are carnauba and synthetic waxes or film release agent PVA. It is not solvents in the spray adhesive that are responsible for adhesion, but the viscoplastic adhesive bond.

Processing with epoxy resins
Polychloroprene dissolves completely only in combination with resins based on polyester, vinyl ester, methyl methacrylate, etc. When used with epoxy resins, it is assumed that the adhesive, provided it has not been overapplied and thus does not significantly impair the permeability of the dry fibre reinforcements, exerts only a relatively minor influence on the subsequent mechanical properties.
This is state of the art and means that used correctly, the products are also compatible with epoxy resins.

Vacuum infusion
In the case of vacuum infusion, a topcoat (e.g. UP-Vorgelat or suitable 2K coatings) is typically first applied to the mold, and the layer build-up is then started. This prevents adhesion of the spray adhesive to the surface of the mold.

Without a topcoat, not only is the molding of the components more difficult but there is also spray adhesive directly on the surface, which must be carefully removed before a further painting process.
