Dive deeper into specific product variations

Neutral cure is safe for metals and mirrors. Acidic cure is stronger but releases acetic acid — not suitable for sensitive substrates.

PU offers higher strength but contains isocyanate. MS Polymer is eco-friendly, paintable, and odorless — ideal for interior use.

Silicone excels in weather resistance and temperature range. MS Polymer wins on paintability and eco-friendliness.
