Scott Bader Crestomer 1186PA (25kg)
Crestomer 1186PA is a multi-purpose gap filling structural adhesive for a wide range of FRP applications. It is based on Scott Bader?s unsaturated urethane acrylate technology and exhibits very good impact strength, toughness and resistance to crack propagation. Crestomer 1186PA also shows outstanding adhesion to a wide range of metals, ceramics and polymeric materials and provides structural adhesion even when bonding FRP laminates with a 30mm thick bondline.
Features and Benefits
Urethane acrylate base: Excellent adhesion and good elongation at break
Highly thixotropic: No sagging on vertical surfaces
Colour change system: Visual check for effective catalyst mix
Crestomer 1186PA has a Statement of Acceptance from Lloyd?s Register of Shipping for use in the construction of craft built under their survey.
Crestomer 1186PA has excellent adhesion to FRP material provided that the surface has been maintained free of dust and grease. This can be guaranteed by the use of proprietary strippable cloths such as peel ply (without lubricant contaminates). If the laminate surfaces are more than 3 days old, it is recommended that they are lightly abraded and wiped with acetone or styrene on a lint-free, clean cloth prior to bonding.
Crestomer 1186PA is supplied pre-accelerated. The required hardener is Butanox M50 (or other equivalent MEKP catalyst). The catalyst is added at 2% w/v. Once the catalyst is incorporated, the colour will begin to change from blue to pale grey. Crestomer 1186PA can be applied with a spatula or from a dispensing unit, taking care to keep air entrapment to a minimum. A time lapse of 1 hour from gelation should be allowed between layers. Application should always be carried out at temperatures above 15?C. Recommended temperature range for application is between 18?C and 25?C.
The use of additional pigments or fillers is not recommended as they can affect the performance of the adhesive.
