Reaction adhesives

Reaction adhesives based on MMA/PMMA are polymerization adhesives consisting of one or more components.

They cure by chemical reaction (polymerization) upon exposure to light or UV radiation, or upon addition of catalysts.

They act by partial dissolution of the adherend surface by the monomer. This causes the polymer chains to swell and become interlocked. During curing, the monomer forms new polymer chains that promote bond strength by additional entanglement.

These adhesives are gap-filling and highly suitable for area bonding. They provide very strong bonds of attractive appearance that are generally weather-resistant, depending on the desired adhesive type.
