Weicon RK-1300 Structural Structural Acrylic Adhesive, 10560330, 330GM

Weicon RK-1300 Structural Adhesive has high impact, peel, and shear strength.

The system consists of adhesive and activator which are used in the “no mix” procedure. This makes processing easier by eliminating mixing procedures. The product is particularly suitable for bonding large surfaces of many different materials such as metals, ferrites and rigid plastics.

Weicon RK-1300 can be used in mechanical and apparatus engineering, vehicle construction, tool and mould making, the building and furniture industry and in many other industrial applications.

To ensure perfect bonding, the surfaces to be joined must be clean and dry (to clean and degrease use Weicon Surface Cleaner). The highest strength values can be achieved through additional pre-treatment of the surfaces, such as roughening using blasting or abrasive agents. Several plastics, in particular polyamide, PTFE, polyolefin etc. can only be bonded after special surface treatment, for example using fluoridation, low-pressure plasma, corona, flame impingement etc.

The RK Activator is applied, depending on the size of the bonding gap, on either one side or both sides of the surfaces to be bonded (brush, spray, dip). In case of bond lines with a max. of 0.4 mm in width, the Activator only needs to be applied on one side, for bond lines of up to a max. of 0.8 mm in width and/or rough, porous or passive surfaces (chrome, nickel etc.) the Activator must be applied on both sides. For smooth plastic and metal surfaces, approx. 30 g/m² is necessary, for rough and porous surfaces up to 150 g/m² of Activator may be necessary. The evaporation time at room temperature (+20 Deg.C) is at least 5 minutes. A significant advantage to other adhesive systems is that the coated components can be stored up to 30 days at room temperature (+20 Deg.C) without loosing effectiveness.

The Adhesive is applied only on one side and normally on the surface which is not coated with Activator. The size of the bonding gap can be up to 0.80 mm (only if the Activator is applied on both sides). Bonding gaps of 0.15 mm to 0.25 mm in width always have the highest tensile shear strength. For smooth plastic and metal surfaces, approx. 180g/m² of the adhesive are needed, for rough and porous surfaces approx. 300g/m².

The processing should take place at room temperature (approx. +20 Deg.C). Higher temperatures, e.g. +40 Deg.C shorten the positioning and curing times by approx. 30%, lower temperatures of approx. +10 Deg.C increase the respective times by approx. 50% and at down +5 Deg.C almost no reaction occurs anymore.

Weicon RK Construction Adhesives have a shelf life of at least 12 months if stored in a dry room at a constant temperature of approx. +20 Deg.C. At temperatures between +1 Deg.C and +7 Deg.C the shelf life can be extended up to 24 months. This applies for closed original units which have not been directly or indirectly exposed to sunlight. In case of storage temperatures exceeding +40 Deg.C and high humidity, the shelf-life is shortened to 6 months.

Weicon RK-Activator has a shelf life of at least 6 months if stored in a dry room at a constant temperature of approx. +20 Deg.C. At temperatures between +1 Deg.C and +7 Deg.C the shelf life can be extended up to 24 months. This applies for closed original units which have not been directly or indirectly exposed to sunrays. In case of storage temperatures exceeding +40 Deg.C and high humidity, the shelf-life is considerably shortened.
