two component methacrylate-based reaction adhesive, high strength adhesion, residual elasticity, utilized with the "no mix process" (no mixing!), transparent, colourless, temperature resistant from -40 °C to +130 °C (short term to +180 °C), hazard warnings: glue: F highly flammable, C caustic, activator: Xi irritant, F highly flammable, O oxidizing,
Attributes: Weicon RK-1500 is a fast curing (at room temperature) two component reactive adhesive which is based on methacrylate and is suitable for two-dimensional bonds. This adhesive has residual elasticity when cured. The curing process begins as soon as the adhesive is joined to a surface that has been moistened with the activator. Surfaces that have been coated with the activator can be glued for up to 30 days without having to worry that the reactivity of the activator will decline. This adhesive will fill gaps up to 0.8 mm (when both sides have the activator applied to them). After 5 minutes it is already strong enough to resist being pulled apart. After 24 hours the extremely high-strength final bond has been achieved.
Applications: The RK-1500 can be used to bond practically all metals (coated ones as well), most plastics (except PP, PE, and Teflon), wooden materials, ceramics, glass and stone. Note: this adhesive cannot be used on rubber!
Treatment: The prerequisite for flawless bonds is a clean and dry surface. Greater degrees of adhesive strength can be achieved by pre-treating a surface, e.g. roughing it up. The activator should be thinly applied with a brush on one of the adherends where it will evaporate after about 5 minutes. In the case of smooth plastic and metal surfaces, about 30 grams per sq. metre will be required; for porous surfaces up to 150 grams per sq. metre will be necessary. The honey-like adhesive glue component should be applied to the second adherend surface. After that, the pieces should be joined, positioned and affixed with a small amount of pressure (e.g. with a hand). The curing (polymerization) begins when the adhesive comes into contact with the activator (fairly secure after 5 minutes). In the case of bonds up to 0.4 mm, application of the activator to one side is sufficient; for larger bonds, up to a maximum of 0.8 mm, the applicator must be applied to both sides.
