Composite Bonder RTP01

Composite Bonder RTP-01

Flexible, but TOUGH!


Impact resistant rubber toughened polymer will support almost anything you stick to it!


Composite Bonder RTP-01 is a premium grade, toughened methacrylate adhesive, used to create a fast curing, strong, flexible bond to a wide variety of substrates. It is used for room temperature bonding of Fiberglass Reinforced Products, Composites, Metals, and plastics (ABS, PVC). This adhesive is designed to produce tough, impact resistant, fast curing joints for applications in the Marine, Recreation, Construction and Transportation industries.

Can be used to attach many dissimilar materials to Solid Surface, Granite or Engineered Stone, such as Steel, Aluminum, and Fiberglass Composites, PVC, ABS, etc.
High shear, tensile, and impact strength allows for attaching bolts, sink fasteners, metal supports and stainless steel sinks. You have to try this to believe how strong and flexible it is.
Packaged in the same 250ml cartridges as our Surface Bonder adhesive, so there is no need to buy a separate dispenser. Also available in our 100ml cartridge which will fit in any standard caulking gun!
This is a great product for around the shop, with steel to steel bonds of approx. 3000PSI (Lap Shear strength) and the ability to attach dissimilar metals and plastics, its uses are unlimited.

Composite Bonder RTP-01 is the recommended adhesive for installing under mount fasteners to Solid Surfaces, Natural Stone and Quartz Surfacing materials, due to its high strength, flexibility and impact resistance. Composite Bonder RTP-01 requires little or no surface preparation in most applications and remains flexible at low temperatures with excellent impact resistance. It is 100% reactive (contains no solvents) and is shelf stable for up to one year.
