Latent single-component epoxy expansion: SikaRecent Research Landscape

Premature activation of expandable resins leads to shelf-life degradation and hazardous outgassing. This technology engineers the chemical latency of the curing and foaming agents to ensure stability until thermal triggering.

What technical problems is Sika addressing in Latent single-component epoxy expansion?

Insufficient structural gap filling

(7)evidences

Weak adhesion between electrical steel laminations leads to structural failure and reduced magnetic efficiency. Improving bond integrity ensures mechanical stability under operational stress.

Premature resin curing instability

(6)evidences

Inadequate shelf life due to early reaction and insufficient mechanical expansion limits. Improving stability and elongation prevents material failure and processing waste.
