Plexiglass Acrylic Glue
Plexiglass Glue - ePlasics stocks and sells the complete line of IPS Weld-On Industrial Plastic Adhesives - glue for plexiglas acrylic sheets.
IPS #3 is water-thin, quick drying and is mostly Methylene Chloride in composition. Good for gluing small parts where fast drying is required and bond strength not as critical.
IPS #4 is water-thin, and a bit slower drying. Most commonly used for 80% of Plexiglass fabrication tasks.
IPS #16 is syrupy or bodied and fast drying. Great where the parts don't fit exactly right, for putting a bead inside a box you are trying to make water-tight, or for bonding applications where a bubble-free bond is not required (bonding solid colors for instance).
IPS #40 is mostly acrylic monomer in composition and is a 2-part mix. This is the adhesive used by professionals for making aquariums and other bubble-free and highly structural bonds. It is the strongest of all the Plexiglass glues, and requires a bit of skill in its application. Excellent for bonding Plexiglass to other materials as well.
